mattx86LT, btw, I found another provider, one in the netherlands - liteserver.nl [01:26]
LTyou're really searching hard aren't you? I signed up for portfast a few days back... seems ok so far [01:26]
mattx86if you check WHT, they have a 128MB VPS for 6 EUR (not sure if they still accept it)
hehe yeah :)
good to hear
[01:26]
LTthe fact they are also a registrar that does v6 glue was a welcome plus [01:28]
mattx86I didn't know that.. that's pretty cool
they're a reseller tho right?
not that it matters really
[01:28]
LTnot for .uk as far as I can tell, but I think they resell tucows for some other tlds [01:31]
***schmir has joined #arpnetworks [01:31]
mattx86ah
fwiw, so far so good with goscomb here
I'm considering switching to liteserver tho because 1) they're offering 750GB bandwidth (not sure that I'll need it, but just in case) and 2) their routes are amazing from what I've seen here (and about 20ms less on pings than to goscomb)
for the same price or cheaper too
with exchange rates
not sure what their support is like though
well, coupon(s), exchange rates, and plans
[01:32]
LTcan't hurt to try it for a month I guess [01:40]
mattx86yeah, that's what I'm considering doing
I'll mull it over
[01:41]
LTmy only worry would be they're xen rather than kvm.. had odd experiences with xen in hvm mode before [01:42]
mattx86that's actually what goscomb uses (well, Citrix XenServer, the commercial version IINM)
but yeah, I'm using goscomb in HVM mode
no problems (yet) ;)
its not clear tho, whether you can install just whatever you like at liteserver
kinda sounds like a no ("Other OSes are available on request")
in other words, they're probably running in PVM mode.. but I'll check later I suppose
[01:44]
LTI suspect what it means is we have these OSes as PVM but if you want something else you can have HVM and install yourself [01:50]
mattx86true, it could mean that
that's what goscomb does
[01:51]
LTyisp do that as well [01:52]
mattx86have you used yisp btw?
their web design kinda scared me off for one thing
I mean, it's not bad.. it, I guess, lacks content more than anything
[01:52]
***killring has quit IRC (Ping timeout: 276 seconds) [01:55]
LTyeah... got it half price on wht some time back, their connectivity is ok, but having some issues with the system hanging
seems like sometimes the disks just drop out... think it's some xen hvm issue and as most of their customers are pvm they haven't really put that much time into working it out
[01:59]

glad I stayed away then
btw, are you using linux too, or say freebsd?
[02:05]
LTlinux... learning freebsd is on my list of things to do on a rainy day [02:08]

hedahow does arp share out cpu resources? does it guarantee a certain number of cycles with bursting when the rest of the cpu is idle or what? [06:05]
***nakano_ is now known as nakano [06:15]
toddfheda: not over-allocating means dividing the cpu power in a given system amongst kvm systems so that each kvm system can have its allotted cpu slices fully w/out degredation
aka if there is 8 3ghz cpus in a system, there could be 24 1ghz kvm instances ..
but that is just an example, I am honestly not sure how arpnetworks works that out but they are quite clear about not over-allocating memory and cpu
it is truly amazing but my physical hardware laptop is slower than my kvm instance at arpnetworks.. md5 speedtest results:
my laptop: Speed = 76614086.419157 bytes/second
arp kvm: Speed = 430477830.391735
there have been some benchmarks (unofficial of course) that show arp is much faster in general than other vps providers

ziyourenxiang has joined #arpnetworks
[06:45]
hedatoddf: thats cool, i know some providers equal split the cpu resources as a 'dedicated' cycles but then if there's a load from one vps and other vps's aren't using their cycles you can burst until the other vps needs them back [06:50]
toddf: i'd image also that the md5 test results are down to raid 10 throughput rather than anything else [06:56]

mattx86hm.. anyone know if nagios would allow you to run a traceroute if latency/packet loss flaps to and from certain thresholds during a specified period of time, and e-mail you the traceroute(s)?
I'm not running nagios (or anything at the moment), but I've been considering writing my own network monitor app
specified period of time = say, within a 20 second window
[16:33]
Leftyyou can write arbitrary nagios plugins in whatever language, it's just got a specified output format
so the email would have to be out-of-band, as nagios just gets pass/warn/fail I think
wouldn't be that difficult though
[16:42]
mattx86sounds doable [16:44]
RandalSchwartzyou can give exteneded output in the status
arbitrary text
you'll have to drill down in the interface though
or wait... you can have it be part of the email
might be by default
... http://nagios.sourceforge.net/docs/3_0/pluginapi.html
see the "long text line 1"
$LONGSERVICEOUTPU$ macro for the email
so yeah, you can do it... just gotta write your plugin to do what you want
[16:44]
mattx86I think I'm still leaning towards implementing it for my own network monitor app
I've got a lot of great ideas for one
[16:48]
RandalSchwartzyou and 50 others :) [16:49]
toothOnly 50? [16:49]
mattx86RandalSchwartz: what was the idea you had the other day, if you don't mind telling me? [16:49]
RandalSchwartzwhere 50 means "uncountable" :)
which idea?
[16:50]
toothAh, I sit corrected. [16:50]
mattx86something about when to send notifications, like queue them until the 9-5 period of the day, I believe [16:50]
Leftyyeah, researching network monitors always felt like a million monkeys on typewriters to me [16:50]
RandalSchwartzahh. lemme think [16:50]
mattx86there's another idea - allow the user to specify the timezone for notifications too [16:51]
RandalSchwartzthat's already there [16:51]
mattx86e.g., for international cooperation [16:51]
toothJust don't bring the pager home. :-) [16:51]
mattx86lol yeah [16:51]
RandalSchwartzmv pager /dev/toilet [16:51]
toothMine just stays at work. :D [16:52]
mattx86the flapping on the wireless network forced my last boss to stop using his pager until I adjusted the thresholds to something that 'worked' ;) [16:52]
toothflapping on wireless networks was worthy of a page? [16:53]
RandalSchwartznagios at least has that figured out
notify at first breakage
[16:53]
mattx86it was important to me anyways. we'd normally get 1 to 10ms on a good link [16:53]
RandalSchwartzthen don't notify "up again" until up again in a long enough ratio [16:53]
mattx86maybe 25ms [16:54]
LeftyI liked the idea of having a "flapping" status, too
we currently use ipMonitor 9, which is way too basic for what we do
I hate it
every other NMS sucks worse though
[16:54]
mattx86btw, does nagios properly do notifications in a network hierarchy? [16:55]
RandalSchwartzyes
you can tell it "this hides that"
[16:56]
mattx86last time I tried nagios, despite specifying parent nodes, it would notifying me of everything below the parent that was down [16:56]
RandalSchwartzso it will only complain about the nearest border [16:56]
Leftynagios is a bit of a whore to configure, true [16:56]
mattx86s/notifying/notify/
this was actually nagios 2.0b3 or something :P
[16:56]
bob^^i'm late to this discussion, but if you like nagios, take a look at Opsview
it's nagios (but with improvements) and a *very* useful/usable/stable frontend
also makes scaling nagios across multiple servers very simple indeed
[17:00]
mattx86interesting.. is the community version just as good? [17:03]
bob^^yup
we use the community version in work at the moment (i work for an ISP)
one master server, three slaves which run checks and a dedicated database
[17:04]
mattx86nice
I'll take a better look at it later
I'll bbl
[17:04]
bob^^there's #opsview if you need info :)
or just give me a shout
[17:05]
mattx86cool, thanks :) [17:06]
up_the_ironsbob^^: will it run on openbsd? :)
i've been meaning to migrate my old nagios setup to my new openbsd atom box
[17:17]
jdoeif nagios works but you hate how it looks, why not just look at the alternate frontends?
I mean I hate how nagios looks, but it's not like I have to look at it on a regular basis or anything.
[17:21]
toothif you do, you're doing something wrong [17:26]
jdoeor other people are ;)
I dunno, we have the dashboard thing up on a monitor here, but that's more just a convenient status board.

RandalSchwartz"will it run on openbsd" is related to "will it blend?" :)
