bashas has joined #arpnetworks bashas: hello everyone
i'm asking for a good windows vps provider
any suggestions? mnathani: bashas: budget? bashas: no limits
but i need a good reviewed one
with a good spec mnathani: check VPS offers at: http://www.webhostingtalk.com/forumdisplay.php?s=1c5bb91bee9812bf871e252e57078dda&f=104
'good' can mean different things to different people :-) bashas: yes :) i know
but anyway, tnx dude for ur help
checking the forum mnathani: you are better off asking stuff like: so much RAM, managed vs Un managed etc ? Disk Space, Location bashas: what's managed an unmanaged? a new term to me? btw i'm a web developer
and i need to host a project, it has few hits daily, but do some processing every few mins using C# threads mnathani: if you have to ask, you probably need managed
unmanaged is like no software support from the hohst
you need to take care of all software install and config bashas: the project aim is to download some html pages and parse them, and extract data from it and put into a sql db mnathani: host will only support underlying network and virtualization, power etc bashas: unmanaged is a shared windows u mean, right?
but managed is a full windows machine with total control, am i right mnathani: the box will be shared, you will have total control on your own instance
admin / root access
https://www.liquidweb.com/storm/vps.html
those guys are pretty good bashas: i know they are shared, one server hosts few Virtual Machines mnathani: right
anyway got to go bashas: ok np bro.
thanks very much
i'll try to google and understand the deep details of manage and unmanaged brycec: Managed: The host/provider "manages" the system, installing updates, changing settings, all the server admin stuff for you.
Unmanaged: You're responsible for maintaining the server, keeping software up to date, etc.
ie. your home computer is unmanaged.
Whereas in a corporate environment with corporate IT, your work computer is "managed"
Hope that clears things up BryceBot: That's what she said!! bashas: brycec: very useful
thanks dude :) ***: bashas has quit IRC (Quit: http://www.kiwiirc.com/ - A hand crafted IRC client) mercutio: is someone trying to get rid of windows users? :)
i suppose if someone asks if they need manager or unmanaged they need managed.
oh mnathani said that :) brycec: lol
I dare say that a whole VPS for a small site is overkill too
but I'm not too experienced in the windows hosting arena... maybe there are providers that won't allow you to run your own program periodically?
(Regardless - sounds like something that a LAMP stack could easily do)
Man - when a SAN runs out of disk space, servers really don't handle that well
(for loose definitions of SAN and server)
(KVM machines with NFS-backed storage, to be exact) m0unds: if it's just for a site, azure sites works well enough
there's other stuff that can run asp in a similar containerized env too brycec: Azure has a free tier too, as I recall m0unds: yeah, that's how i played with it
supports code repo autodeployment too (ala heroku) mercutio: i think background stuff could be annoying on shared windows hosting
i'm paranoid about shared web hosting myself m0unds: background stuff?
i finished building my "less complicated" fermenter controller today mercutio: he said about c# threads in background or something? m0unds: oh, probably similar to background php processes or whatever brycec: I figure it's roughly equivalent to a cron job m0unds: yeah
just executing at some interval mercutio: does shared hosting normally let you do that? -: hazardous waves hazardous: shared windows hosting is infuriating to deal with m0unds: no idea, haven't ever used windows shared stuff hazardous: i really really dislike shared anything with asp.net
because of trust level/privs
and most shared hosts don't like to give full trust
and for a lot of things, you have to contact the host
tend to kind of just run it in a vm because effort m0unds: probably similar cost-wise as vm stuff keeps getting cheaper hazardous: the problem is that it tends to restrict your choice of hosts
because windows licencing is opening schrodinger's dvd case brycec: (Every shared lunix host I've had lets me schedule cron jobs, fwiw) hazardous: that being said.. i do have a shared hosting account on a linux place i like, because they let me run my own apache/nginx/rails/python server like flask or something, and just let me use a port to reverse proxy it from frontend loadbalancer
and allow compilers/installing binaries/etc
but that's literally the only 1 single linux shared host i know that does that, everything else is terrible
i hate cpanel/plesk/etc with a passion
cpanel still claims to support python and ruby on rails, which is a massive, hilarious lie
tbh i feel like the adoption of non-php web languages is partially because of control panels (and a bit on the languages themselves)
php is drag and drop, and visit url
that has never been, nor will it in the near future be the case for nodejs, python, ruby, [...]
and without ssh access, in general, it's borderline impossible to run on shared hosting staticsafe: yeah
PHP apps are stupid easy to deploy hazardous: as dumb as it is, being able to simply upload index.php and be able to visit index.php
if you try to explain the concept of routes to someone that "just wants a forum"
many people don't seem to be able to parse the concept of "upload index.php, and you can visit /login"
so not supporting apache's single-file .htaccess rewrite thing (which is kind of inefficient since it seems to recurse every subdirectory and whatnot)
as far as most of the people i deal with know, .htaccess is black magic BryceBot: That's what she said!! hazardous: the thing that pisses me off the most is that really shitty shared hosting providers are not helping
like cpanel hosts that lie about having python support
and then someone tries to "install a python webapp" and it fails miserably -: hazardous hugs BryceBot m0unds: by python support, they mean the host has python installed
not that you can use it
bahaha mercutio: cpanel is "the standard"
it's pretty disgusting yes. hazardous: Posted 1 year ago
Why does CPanel continue ignoring requests for supporting Python/Django
laugh mercutio: i was surprised by how long it took me to get smokeping working with nginx
nginx with fastcgi is a bit confusing. hazardous: at least for php, nginx + fcgi is 4 lines
not so much actual cgi-bin applications mercutio: but i like the idea of micro vps with nginx/php/etc all seperate.
this is perl
you need to use fcgiwrap hazardous: not so much actual cgi-bin applications <- i've never actually had to run something cgi/perl
like for web
i think that was common maybe before i was born but idk m0unds: there's a few ways to plug that support into nginx hazardous: it's just really foreign to me as a concept mercutio: it was easier on ubuntu than arch linux tbh
mod_perl sucks hazardous: reminds me
what happened to gentoo m0unds: i used thttpd as a cgi-proxy years ago hazardous: wasn't it all the nerd-rage a decade ago m0unds: behind nginx hazardous: everyone seems to have moved to arch or something from what i can gather mercutio: i think it's still around
m0unds: i've been using lighttpd for ages, but thought i'd try nginx because nginx is adding spdy support and fastopen support
fastopen is really easy to enable in nginx. in lighttpd i have a source hack. hazardous: nginx pisses me off with their commercial product offering mercutio: hazardous: why? m0unds: they have a commercial product offering?
haha hazardous: i need the ability to kick out unresponsive backends for reverse proxying mercutio: m0unds: yeah. hazardous: this is commercial product only
minimum few thousand a year
required support contract m0unds: ah mercutio: they're still putting mroe effort into their open source offering than anyone else. hazardous: there is no way i can buy like "just want this module"
i don't want support
i just literally want one config option enabled
i don't need SLA, i don't need tickets
but that's totally not available to me
i would happily pay like 50-100/yr just for the ability to use a few extra config options
but a few thousand i can't afford
defining backends to reverse proxy is free - doing anything else with them, like checking if they are online, setting randomization, removing or adding backends
is a $$$$ feature only mercutio: so backends can hang and it can't fix it?
isn't that spawnfcgi's job? hazardous: i have this problem in that my backends are closed-source binaries that i don't have access to, and occasionally they die
i would like to run a script if one doesn't return or sends a 5xx
i would also like to check periodically if they respond
so now.. i use chinese nginx mercutio: are you in china hazardous ? hazardous: no
i'm in freedom-land mercutio: canada? hazardous: wow
close enough brycec: Obviously kicking the backend can be scripted (kill $pid), so you're just missing the ability to query a specific backend directly? mercutio: brycec: yeh how would he know which one to kill hazardous: brycec: http://tengine.taobao.org/document/http_upstream_check.html mercutio: i wonder what happened to dtrace coming to linux hazardous: http://tengine.taobao.org/document/http_upstream_consistent_hash.html mercutio: i kind of like the idea of tracing normal programs hazardous: these are all bsaically nonexistent in free nginx mercutio: and some kind of autodetection of weird behaviour brycec: So it kicks it out of the nginx pool -: mercutio doesn't trust people to not screw up
brycec trusts people to screw up
hazardous greps mercutio mercutio: heh brycec hazardous: screwing up is normal human behaviour mercutio: error handling is often terrible on unix
actualyl with software in general hazardous: brycec: even manually removing a backend temporarily in nginx is paid, iirc
without editing configs
much less having proactive health checks that let you define "after x failures, drop this out, but readd it if it starts responding later on" mercutio: relayd can do that btw hazardous
if you have multiple servers brycec: Yeah - I ran across a "need" (want, really) to do that and found it only came with money hazardous: if you want a laugh, my primary web frontend has 9 VPNs running on top of each other mercutio: but if one out of 4 backends is doing it or something, and it returns 5xx on one of them i dunno how it'd handle that brycec: One could easily kick/restart the backend with your own script though, but it does nothing for nginx mercutio: if someone wrote a backend handler that also did performance monitoring etc
they could probably sell it hazardous: capturing the 5xx and identifying where it came from is the thing for me, because i just want to drop it out of my uplinks for a while until my watchdog processes notice and restart it
tengine's upstream_check thing lets you set things like timeout msec, expecting 200 OK or 302 or something, and checks ssl handshakes
by default all backends are offline until they pass their first check
i really wish i could just use stock nginx, i'd be happy to support their efforts and whatnot, but it's just not feasible for anything not business mercutio: what about sticking a wrapper program around your binarys hazardous: define wrapper program
[they are windows binaries that listen on a port, running on remote hosts] mercutio: runs your cgi script, sees that it behaves
has an abort if it takes too long, or if it does 5xx. hazardous: i have 1,539 backends mercutio: oh hazardous: lol; mercutio: relayd should handle that then BryceBot: That's what she said!! hazardous: the thing is.. it also returns HTTP 200 for failed requests mercutio: which is bsd hmm. hazardous: with error text in the body mercutio: oh
that's annoying :) hazardous: so i also check if it returns a XML response that contains 'failed_err' mercutio: you could do your own monitoring script and take them out hazardous: there's a few failure states, one of them is named "SHOULD_NEVER_HAPPEN_RACE_CONDITION_TRAP"
i've encountered that af ew times mercutio: are all the backends the same, you're just load balancing to them? hazardous: load balancing to them across vpn, every 150 or so is a different country, some are domestic-internet-only, some are only accessible from one isp
tl;dr asia mercutio: i think your situation is complex enough that it warrants coding for it. hazardous: fun thing of the day, i was told that in south korea, reverse dns is illegal unless i have a south korean business licence, and it can take up to 6 months to complete the application process for a single PTR record, and that delegation of NS/PTR/CNAME is not allowed mercutio: wow. hazardous: all PTR requests have to go through KRNIC
if you've ever wondered why almost no south korean ip has a PTR, well, that might explain it maybe mercutio: china doesn't have PTR either ? hazardous: china occasionally has isps that have applied for PTR for their whole netblock
none of which have forward dns, most of them completely invalid
lol
this is basically standard for all of asia
my upstream in vietnam assigns datacenter colo, dynamic adsl, dialup, voip, and iptv out of the same subnet
i can pull a dynamic adsl ip from colo, from standard dhcp pool
all static IPs have the reverse dns 'dynamic.vdc.vn', and this isn't editable
they have several /16's that consist entirely of 'dynamic.vdc.vn' exactly, not unique ptr per ip
theres also the whole "having to bribe customs and shipping officials or else your hardware gets stolen" thing mercutio: wow.
has anyone tried the new apache httpd?
err new openbsd httpd brycec: lol way to goof that :P mercutio: i'm not exactly sure why openbsd is doing their own httpd
back in thttpd/boa/lighttpd/etc days there were heaps of them
i jumped from boa to lighttpd myself BryceBot: That's what she said!! brycec: Same reason they do their own everything - to keep full control over it hazardous: openbsd made a httpd? mercutio: yeh based on relayd it seems. brycec: So more pf.conf-style syntax! mercutio: looks like it's pretty basic
they also made their own smtpd
i like relayd. brycec: httpd is extremely basic at this point hazardous: all i want/need is static file serving from a dir brycec: OpenSMTPD is pretty great mercutio: sendmailis prettty bad staticsafe: opensmtpd is awesome, i wish there debian/ubuntu packages for it
its in sid but thats about it mercutio: there needs to be linux kernel with openbsd userland :) hazardous: that exists
it's called windows
:)
what's the "in" orchestration tool nowadays
puppet? ansible?
it seems to change weekly brycec: puppet and chef are the big "in" ones from what I can see
But there's still a lot to be said about using the right tool for the job
such as ansible in my case staticsafe: ansible <3 twobithacker: ansible++ brycec: ansible++ RandalSchwartz: ansible has some interesting advantages
we interviewed them for floss
along with puppet, chef, cfengine, saltstack... :) brycec: I needed something to do some basic script-able tasks, without reinventing the wheel myself. Ansible gives me that and a bit more. I was up and running in ~minutes, rather than the overhead of chef or puppet. hazardous: so the nerd portion is ansible
i don't want massive overhead, custom daemons, etc ***: erratic has quit IRC (Ping timeout: 258 seconds)
erratic has joined #arpnetworks
mus1cb0x has joined #arpnetworks
mus1cb0x has left "WeeChat 0.4.2" mnathani: hazardous: reading the scrollback, what was that shared linux host you found that let you run your own web server?
This looks like a really cool position: https://ams-ix.net/about/careers--2/project-stagiair-noc mercutio: you going to apply mnathani ? mnathani: mercutio: if only I met the requirements
:-) mercutio: i don't think it had many requirements?
it sounded like it'd be a bit boring though
Following this project, the internee will follow/collaborate with
AMS-IX network engineers to work on
it's bsaically just a testing/scripting job from what i can see mnathani: I suppose they would have some basic on the job training mercutio: it's also probably in amsterdam
but yeah what they're doing sounds interesting
i'm trying to add high dpi support to smokeping
i got the overview looking better..
but smokeping isn't saying the size for normal images when you go to the page :( so i can't just half it. acf_: > isn't saying the size for normal images
isn't saying it where? mercutio: in the html acf_: oh mercutio: it's just referencing the made image
apparently the way to make high dpi work easiest, is you just define the size as half of the actual image size.
and high dpi displays will show all the detial. acf_: got it
you could mess with the image generation I guess BryceBot: That's what she said!! acf_: is it really? mnathani: BryceBot: no BryceBot: Oh, okay... I'm sorry. 'you could mess with the image generation I guess' mercutio: i am doubling the rrdtool created image size
and want to touch smokeping as little as possible. BryceBot: That's what she said!! mercutio: BryceBot: no BryceBot: Oh, okay... I'm sorry. 'and want to touch smokeping as little as possible.' acf_: does smokeping just invoke the rrdtool command with some args? mercutio: i think so
# HIGH DPI
$xs=$xs/2;
$ys=$ys/2;
that in the right place fixes the overview. BryceBot: That's what she said!! mercutio: with just doubling the size in the config. mnathani: BryceBot: no BryceBot: Oh, okay... I'm sorry. 'that in the right place fixes the overview.' acf_: because the overview defines the size explicitly in the html? mercutio: it's perl generated html
and overview does yes.
but detail doesn't.
i could try and understand the code more.. ***: sga0 has quit IRC (Ping timeout: 245 seconds) acf_: mercutio: I'm editing .pm files in /usr/share/perl5/Smokeping
but nothing seems to happen mercutio: got it acf_: what did you do? mercutio: you have to restart fcgiwrap
i found that $xs{''} is used somewhere else
and added in width and height with that
i haven't done much perl acf_: cool mercutio: what's the difference between $xs and $xs{''}
i think the smokeping code is messy :)
http://pastebin.com/tPWXf0an acf_: curly braces are used to access hash tables? -: acf_ doesn't know perl either mercutio: http://202.49.71.24:24/smokeping/smokeping.fcgi?target=Wider.google
that's got it running on it
now i just need the text size bigger... BryceBot: That's what she said!! acf_: looks super tiny on my monitor :P
it would be cool if rrdtool rendered svg instead of raster mercutio: the text or graph?
i think rrdtool can
i just wanted to start with something acf_: well, all of it mercutio: you mean the graph is small or the text is small? acf_: the text mostly mercutio: yeah the text is small for me too acf_: on my monitor, it's a bit blurry mercutio: the text on the left is a little small, the text in the image is tiny acf_: probably because of the scaling mercutio: i'm at 1440p
but yeah the text size needs to be bumped up BryceBot: That's what she said!! acf_: I'm at 1024x768 atm mercutio: do you use 100% zoom?
oh acf_: yea mnathani: ouch at 1024x768 acf_ mercutio: so yeah high dpi won't help you at all BryceBot: That's what she said!! acf_: nope :P mercutio: still it should work without high dpi too :)
it'll still be blurry a little probably mnathani: I just moved down to 1 1080p display, from 2x 1280x1024 + 1x 1080p mercutio: i have 4k+1440p mnathani: Windows or *Nix? mercutio: 1440p on windows and 4k on linux
chrome sucks on linux at 4k though
text looks amazing though :)
consoles are so ... nice... :) mnathani: white banners on right and left? mercutio: huh? mnathani: how many inches on the 4k display? mercutio: 28"
vs 27" for 1440p
it hardly looks any bigger tbh
they came down in cost a lot mnathani: the white regions when you make the browser full screen mercutio: i'm using radeon 7750 for video
oh i mean scrolling is slow
and i haven't been able to make url bar big yet
actually scrolling was slow on 1440p too
it just got worse
the video card should be fine...
i think it's sucky open source drivers. acf_: I wonder if I just change all the .png s to .svg in smokeping...
arrg
so it seems like certain edits to Graphs.pm aren't applying
I change .png to .svg everywhere, but the page still renders with .png
but if I put some garbage at the top of the file, it correctly fails to load
it worked!
changing all png and PNG to svg and SVG in my Smokeping.pl works
it displays a bit big though...
adding width="$xs{''}" height="$ys{''} in the right place fixes the size...
example: http://kremvax.acfsys.net/smokeping.cgi?target=Remote.googledns
mercutio: how does that look on your high-dpi monitor? mercutio: the text looks a bit funny
i think the font is just crap
umm rrdtool needs a parameter to generate svg
oh it is svg
does it autodetect?
i should try on my 4k
erk
can this font be changed, it's really annoying mnathani: mercutio: you try the proprietary driver? mercutio: it looks fine
mnathani: nope
i really don't want to use binary video driver.
i suppose svg is probably better in general hazardous: mnathani: just read scrollback; webfaction.com mercutio: my pngs are smaller than your svg
by 40k vs 137k
i wonder what it's like if making the size even bigger acf_: > < mercutio> does it autodetect?
'--imgformat','SVG', mercutio: heh i can't read the text now mnathani: hazardous: looks really good so far. I am surprised I have never heard of them before acf_: yea, can't figure out how to change the font
tried adding --font to the options, didn't work afaict mercutio: http://202.49.71.24:24/smokeping/smokeping.fcgi?displaymode=n;start=2014-11-20%2014:28;end=now;target=Curl.garlic
this to me looks kind of how i want it BryceBot: That's what she said!! mercutio: now sure how it looks for other people
but yeah need to ramp up text size BryceBot: That's what she said!! mercutio: i want to change fonts too, i have this annoying 0
it looks like there's a little eye poking out in the middle to the right slightly acf_: yea
where does it get the fonts?
I'm guessing not X11... mercutio: i have no idea acf_: ok so --font does work
at least for changing the size
but I don't know what other typefaces to give it besides monospace mercutio: what's eps? acf_: enhanced post script
it's a vector format mercutio: do browsers support it? acf_: I think chromium does
*encapsulated post script mercutio: i hate it how they double all these things up
well more than double
so there's more than one place to set font acf_: only two? BryceBot: That's what she said!! acf_: that I could find
look for --imageformat
* --imgformat
I added
'--font','DEFAULT:0:monospace', m0unds: mercutio: this is how it looks for me: http://i.imgur.com/YG5DTMX.png mercutio: i'm looking for --rigid
oh it is only double for that one
wow the text on the left looks terrible m0unds: that's on osx in chrome mercutio: ERROR: unknown option '--font DEFAULT:28:Times'
oh acf_: "RRDtool uses Pango for its font handling"... cool m0unds: font rendering is better in safari but i don't really use safari ever
don't ever use safari* mercutio: damnit now it doesn't fit acf_: oh nice Times worked mercutio: yeah it wokred
http://202.49.71.24:24/smokeping/smokeping.fcgi?target=Wider.gmail
but it all wraps !
and it's all blurry
not even blurry it's low res acf_: blur probably from dithering? mercutio: maybe i should stop halving the size acf_: that's probably causing it mercutio: can't the text scale?
http://202.49.71.24:24/smokeping/images/Wider/sip99_last_10800.svg
even that looks terrible acf_: woah mercutio: it's uhh yeah acf_: I think you're using a raster font.. mercutio: that's what i meant
are you not? acf_: let me check... mercutio: i should install the microsoft fonts? acf_: with Times: http://kremvax.acfsys.net/smokeping/images/Remote/googledns_last_10800.svg
Helvetica works too
this is with Debian
I don't think I installed anything special.. mercutio: oh yours is way better
this is on server rather than desktop
so probably has less fonts installed acf_: same here
no X11 on that box mercutio: oh
i'm downloading the microsoft ones
your one looks fine
does everything support svg these days? acf_: I think so
find /usr/ | grep -i times
turns up nothing
http://en.wikipedia.org/wiki/Scalable_Vector_Graphics#Native_browser_support BryceBot: Scalable Vector Graphics :: Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created a acf_: IE9 + suppors SVG mercutio: i don't care about ie i suppose :) acf_: everything else has supported svg for a long time mercutio: ok
what version of windows did ie9 come in with? acf_: released March 14, 2011 mercutio: /usr/share/fonts/TTF/times.ttf acf_: supported on Vista and above mercutio: gah it still looks terrible m0unds: haha
try sans serif?
or serif? mercutio: maybe i have to do something to register it? RandalSchwartz: o/~ I shot the serif ... o/~ m0unds: RandalSchwartz: aarrrggghhhh
hahahaha acf_: fontconfig?
I can't find Times or Helvetica anywhere...
fc-list | grep -i times
shows nothing
maybe it's using DejaVuSerif instead? mercutio: # fc-list | grep -i times | wc -l
52
# fc-list | grep -i dejavuserif | wc -l
8
how do i tell what it's calling rrdgraph with hmm acf_: DEFAULT:0:DejaVuSerif
appears to show the same output as DEFAULT:0:Times
so it's probably just using the DejaVu fonts mercutio: oh it's calling the module
it definitely changes something
http://202.49.71.24:24/smokeping/images/__navcache/141645903735734_1416459037_1416448200.svg
i'm only setting title
and only the title is ugly :) m0unds: yeah it is
lol
the rest looks ok though acf_: the other stuff looks like it's still monospace (Courier or whatever) m0unds: yeah mercutio: oh consolas looks better m0unds: looks like the default smokeping typeface
consolas is my fav fixed width font
i use it in putty on windows acf_: ah nice mercutio: http://202.49.71.24:24/smokeping/images/__navcache/141645913735819_1416459137_1416448320.svg m0unds: too big but looks clean mercutio: a bit big, but it looks more sane
http://202.49.71.24:24/smokeping/smokeping.fcgi?displaymode=n;start=2014-11-20%2014:53;end=now;target=meh.sydmeh
ok that's starting to look better m0unds: yeah, that looks good
little big still but much better all around mercutio: i want the text for overview a bit smaller though acf_: some things broke :P
http://oss.oetiker.ch/smokeping/counter.cgi/2.006010 mercutio: i put it down a step, now it looks too small acf_: http://202.49.71.24:24/smokeping/images/smokeping.svg
rather
it still looks super big on my screen mercutio: oh? acf_: (the 1024x768 one) m0unds: yeah, the last time you linked it the text at the bottom was bigger than the title
it wasn't overlapping like it was before though, just big mercutio: http://202.49.71.24:24/myscreen.png
i suppose it is kind of big acf_: ah. looks nice on that screen m0unds: yeah
my macbook is pre-retina, so it's got a pretty low res display mercutio: i'm using cheap korean monitor
qnix m0unds: so it's really big for me but would look fine on my workstation display i'm sure (since it's the same res as yours) mercutio: 1440p is actually quite a nice resolution
it works ok in winodws too
4k is screwy in windows acf_: are the Windows icons vector or at least available in many sizes? mercutio: but yeah the cool thing about svg is that it can scale i suppose
what windows icons?
i don't think they've vector acf_: like the taskbar ones, etc.. mercutio: they look rpetty blocky acf_: I can see it would be difficult to support 1024x768 and 4k at the same time
if you're just using a single scale of raster images
it would be cool if they had a system where you could change the dpi without changing the visible size mercutio: well 1280x720 and 2560x1440 is just x2
but smokeping isn't really good for 1024 across
as with 1024 you don't want to show a side bar
i should try on my phone acf_: Android? mercutio: yeah
choosing the site on the left sucks
gah
it keeps crashing
my phone is 720p acf_: crashing.. by trying to render SVG? mercutio: the image itself is fine
it's the other page it seems it screw up on m0unds: worked okay for me in chrome on android mercutio: when there's heaps of them
the overview page with heaps of them
even just going to the curl page is slow acf_: it takes a long time to render the svg on the server? mercutio: gah it crashed again acf_: the browser is the thing crashing? mercutio: chrome 39
the browser is crashing on android
chrome 39 is what i'm using on desktop too
svg on the server is fine speed wise
it's the phone that's slow
that server is in new zealand, so may be a bit slower for you guys m0unds: took 10 seconds or so to display the curl page on my phone
didn't crash or anything mercutio: curl page showed ok
it was other that crashed m0unds: oh, let me try that mercutio: then i clicked on the top curl one and it crashed again
my phone only has 1gb of ram
i dunno if that's why
but no other chrome windows open m0unds: it's taking a while to show m all the graphs - i have a few missing mercutio: and yeh 10 seconds kind of sucks
some are blank in other
i haven't cleaned up this server yet :)
i cleaned some of the others up abit m0unds: 4 seconds on my macbook
10 on the phone acf_: which specific page? m0unds: "other" mercutio: oh it does load a little slow m0unds: just got the "aw snap" on my phone for "other"
haha mercutio: m0unds: yeh that's what was happening to me
and it's what the completion jumped to first m0unds: it loaded most of them the first time, with 3 or so missing
then when i reloaded, i got "aw snap" mercutio: android is so stable m0unds: sometimes
haha mercutio: there's only one fcgiwrap socket
and it's i3 cpu m0unds: ah, gotcha mercutio: so it should have more than one
well if it's going to be slow
it does seem svg does generate slower than ping
png acf_: or it's just bigger, so there is more transfer time?
my phone is swapping to flash on "other" :P mercutio: mind you it's also bigger file size
heh m0unds: hahaha mercutio: i wonder if it's just svg needs tuning in rrdtool
it does look nicer, but i want to change my step time down now :) acf_: mercutio: do you have gzip compression enabled on your http?
that would probably help a lot mercutio: i tried on and off before
a diff day
so maybe it's off acf_: png is binary, svg is xml mercutio: it was always on for /smokeping
it's smokeping.fcgi i was turnig it off/on
oh acf_: ah, ok mercutio: then it's not working for some reason
cos i tried curl -O before
grr
it's huge
wow
it's 240k to 40k just running gzip on it
why it's nginx compressing it
oh i need to define it for that mime type i tink
done
50k rather than 40k
but so be it
and yeah mime type acf_: see any performance difference? mercutio: no
curl --compressed -v -O 0.00s user 0.00s system 5% cpu 0.058 total
curl --compressed -v -O 0.00s user 0.00s system 17% cpu 0.019 total acf_: loads in ~2 sec for me mercutio: that was non compressed first one
curl --compressed -v -O 0.00s user 0.00s system 2% cpu 0.133 total
oh
the 133 msec vs 58 msec
the 19 msec was cached acf_: that would make sense mercutio: it still seems slow :/ acf_: yea mercutio: i have 1 minute expiry set
cos it updates every minute
i think it is a little faster
but yeah if i setup the cgi to run multiple at once it'd make it seem smoother i imagine
actually i don't think it'd make any difference
i think the cgi creates the images acf_: it does mercutio: so the server would have to do it in parallel
i wonder if there's an easy way to do that ... ***: sga0 has joined #arpnetworks mercutio: like async create graphs on various threads, wait for completion acf_: probably not without changing lots of code mercutio: yeah i don't want to touch lots of code :)
the code looked scary
i'm thankful for getting this far! acf_: yea. it's been going rather well mercutio: i wonder if bryce is around
he's running smokeping too acf_: brycec: ^
I think RandalSchwartz is really big on perl.. mercutio: oh you're bryce? acf_: just calling him mercutio: oh right
i think the mobile layout could be improved too
actually i'm going to try on my tablet
err on my crap tablet acf_: there is a mobile layout? mercutio: no
that's the problem
it's really annoying to select hosts on the left m0unds: "other" still ends up hanging on my phone acf_: lol yea mercutio: yeah i think phones have to switch back to png :) acf_: the smokeping web interface could really do with some improvements..
I wonder how hard it would be to rewrite that part in golang or something mercutio: yeah i was thinking of writing my own web frotn end
but it seems that the web front end is tied heavy into the backend acf_: that's what it looks like mercutio: it was one of those things that was coming to me today
the other thing i want to do is quick snmp monitoring of network interfaces with ultra-quick updates
like show on a web page bandwidth per second or such acf_: Cacti?
oh without graphs you mean? mercutio: cacti is per minute
and similar with ping too
something you can go to real time to measure performance
as well as doing it on command line
so it'd do the actual checks with backend acf_: it would be cool to aggregate all that information (SNMP, SmokePing, etc...) m0unds: yeah acf_: also, this: http://stats.sunet.se/stat-q/load-map/optosunet-core,,traffic,peak
super cool imo mercutio: chrome is spastic on my tablet m0unds: i use cacti for local stuff (snmp on my juniper srx and managed switch) mercutio: and it's not full screen acf_: m0unds: you have a juniper srx? m0unds: yeah acf_: I was thinking about getting one of those
what model? m0unds: i have a SRX210HE acf_: what kind of forwarding performance do you get? mercutio: it's a nexus 7 maybe they tihnk i'm meant to be running android 5 or something m0unds: i haven't tested it
it's rated for 800mbit/sec imix iirc acf_: not bad for the price tag m0unds: cpu utilization is a whopping 8% maxing out my 50mbit cable connection, haha
yup
great for learning junos too
has all the features of the big units as well as layer 3 switching and stuff
junos for all occasions
i graph cpu utilization, flow sessions, memory usage, cf storage, temperature and my WAN bits/sec acf_: is there a good way to get the amount of data transferred over a given interval with Cacti?
(on a specific interface)
my "Total In" and "Total Out" numbers are always off.. m0unds: ah mercutio: nexus 7 2012 is being very slow sohwing other in "browser" m0unds: mine's pretty close, it matches what i get when i query via ssh acf_: with svg or png? mercutio: svg acf_: hm, yea mercutio: oh it loaded finally acf_: :P m0unds: haha acf_: m0unds: the thing that disturbed me mercutio: it distorts the graphs heaps when scrolling too
looks a bit funky acf_: is that the "Total In" and "Total Out" numbers for 1 week were larger than the numbers for 1 month mercutio: i bet it's a lot faster on my other tablet acf_: I guess svg s are cpu-intensive to render
especially on mobile platforms.. mercutio: yeah
nexus 7 has a crap cpu m0unds: ...whaaaat? mercutio: actually i don't know if it's /that/ bad m0unds: that's weird mercutio: it's 2012 model m0unds: is the time right on the host and everything? mercutio: what do you mean?
catci doesn't care about time
it cares about uptime acf_: I saw that when I first started using Cacti
I had a lot of data transferred in the last week or so
and none for the rest of the month mercutio: did you reboot the router? acf_: don't think so.. BryceBot: That's what she said!! mercutio: did it wrap around? acf_: wrap around? mercutio: for snmp counters acf_: maybe, I'm not sure
just found another example
"Total In: 184.35 GB" for weekly
"Total In: 184.3 GB" for monthly
this one wasn't that bad
the volume of the other one was in MB
and the numbers were off by at least several MB m0unds: is this a new install? acf_: new as of a long time ago m0unds: ah acf_: Version 0.8.8b
(shipped with Debian) m0unds: was just curious if maybe it was averaging over a month w/only a months' worth of data or something goofy
i don't even know what version i'm on acf_: probably it is doing something like that
it says in the console when you log in
in the top right m0unds: yeah, logging now
logging in
same version here, ubuntu 14.04 acf_: added any new graphs / data sources recently? m0unds: nope, deleted some lately (ipv6 tunnel)
haven't added any though acf_: http://unixcube.org/who/acf/tmp/graph_image-0.png
http://unixcube.org/who/acf/tmp/graph_image-1.png
(had to censor these)
note the "Total In
*way* bigger on the weekly one m0unds: huh
weird
oh cool, spotify got rights to some of the boards of canada b-side stuff they lost a while back mercutio: it does seem weird
can you use sflow acf?
i was distracting getting rid of the stupid borders with smokeping
well rrdtool
you have the silly borders too :)
so is it actually spiking like that? acf_: yea, the spikes are real
which silly borders? mercutio: the gray
light gray and dark gray
there's a line on left hand side and top and bottom and right
and the background colour
of the text etc
i set all of them to FFFFFF
BACK, CANVAS, SHADEA, SHADEB
http://202.49.71.24:24/smokeping/smokeping.fcgi?target=Curl
so it shows like that now
i kind of want to take the rrdtool text out as well acf_: oh those grey borders mercutio: and fix the logo acf_: yea for that you just need to substitute png back in mercutio: what? acf_: > and fix the logo mercutio: oh right yeh acf_: the logo is a png mercutio: apparently you have to hack the source te romev the TOBI thingy
apparently the author is cool with people doing that acf_: I wonder if you can reference it specifically with --font
and set the font size to zero
or the color to transparent
or something mercutio: i'm just going to hack the source
there's a new version that just came out
but hadn't been a new version in two years
doesn't seem to have changed mcuh though
hmm other works fine on my good tablet
and it seems fast too acf_: any svg generation performance change with the new version per chance? mercutio: didn't look like it
was hoping to be haha
http://oss.oetiker.ch/rrdtool/pub/CHANGES
but it may mean there's a new version again soon
i didn't realise rrdtool and smokeping were written by the same guy
