[2009-02-19 10::01:08] mrayzenoss: Good morning all, Ian will be here shortly.
[2009-02-19 10::02:23] teletype: ahh nevermind, found it
[2009-02-19 10::03:23] ** __ian__ joined the chat room.
[2009-02-19 10::04:18] ** kells joined the chat room.
[2009-02-19 10::04:30] mrayzenoss: Kells is here as well
[2009-02-19 10::08:26] ** csayers joined the chat room.
[2009-02-19 10::09:28] cgibbons: crickets
[2009-02-19 10::10:01] mrayzenoss: I guess everything is working great for everybody
[2009-02-19 10::10:39] ** winston joined the chat room.
[2009-02-19 10::11:06] ** winston is now known as Guest23384.
[2009-02-19 10::11:08] teletype: oh I've only just started rolling it out. I'll break plenty of stuff soon
[2009-02-19 10::11:09] cgibbons: i got some bugs i need help with, matt
[2009-02-19 10::11:22] mrayzenoss: cgibbons: lemme guess... WMI?
[2009-02-19 10::12:15] ** nyeates joined the chat room.
[2009-02-19 10::12:24] mrayzenoss: Zenoss Community Day is at SCALE tomorrow, looks like we have 2 slots left
[2009-02-19 10::14:38] malbon: 2 slots? does that include flights and luxury accomodation?
[2009-02-19 10::15:30] mrayzenoss: malbon: nope, it's strictly get there and get free training.
[2009-02-19 10::16:03] malbon: dang nabbit. I was hoping for a freebie
[2009-02-19 10::16:20] mrayzenoss: I think we'll be doing another free training day at LISA in November, in Baltimore
[2009-02-19 10::16:39] ** Guest23384 left the chat room.
[2009-02-19 10::18:00] ** winston joined the chat room.
[2009-02-19 10::18:31] ** winston is now known as Guest48163.
[2009-02-19 10::18:52] ** Guest48163 left the chat room.
[2009-02-19 10::19:38] teletype: is there a way i can have a device push data to zenoss, rather than have zenoss collect the data? in particular i am looking to collect info from laptops that won't always be connected
[2009-02-19 10::20:10] kells: events or things like device performance?
[2009-02-19 10::20:28] teletype: performance, software/hardware inventory etc
[2009-02-19 10::21:12] mrayzenoss: so you want your laptops to push data for when Zenoss can't reach them?
[2009-02-19 10::21:59] kells: What you seem to be asking for might be easier if Zenoss had an agent to install on the device. For performance data, there would need to be something that already collected the data and then could pump it to zenoss
[2009-02-19 10::22:57] teletype: yeah, i'm guessing i'll have to run a script on the laptop to collect whatever data i need and submit that to an externally visible server, and then make a collector for zenoss to go pick that up
[2009-02-19 10::23:20] ** winston_ joined the chat room.
[2009-02-19 10::23:22] teletype: was just wondering if it had already been done so i didn't get to work on reinventing the wheel
[2009-02-19 10::24:44] mrayzenoss: I haven't seen anything like that
[2009-02-19 10::25:15] ** kells left the chat room.
[2009-02-19 10::25:26] ** kells joined the chat room.
[2009-02-19 10::25:34] ** thibaud joined the chat room.
[2009-02-19 10::26:27] csayers: Hi, I have a problem with Zenplugin on Centos - on some of our servers the Used blocks and Available blocks are getting transposed - it appears to be when the filesystem path is long
[2009-02-19 10::26:28] mrayzenoss: do you really need offline monitoring like that?
[2009-02-19 10::26:51] teletype: our windows guys want it
[2009-02-19 10::27:32] mrayzenoss: teletype: I wonder if the nrpe agent from Nagios would work...
[2009-02-19 10::29:21] teletype: nsca is more the functionality i'm thinking of
[2009-02-19 10::29:26] ** int left the chat room.
[2009-02-19 10::29:54] mrayzenoss: teletype: might be worth starting a conversation on the forums, perhaps some other users have tried something similar
[2009-02-19 10::30:25] csayers: yup
[2009-02-19 10::30:42] teletype: will do, when my idea of what i'm trying to do is more solidified
[2009-02-19 10::30:50] ** commarla joined the chat room.
[2009-02-19 10::30:52] csayers: Filesystem 1K-blocks Used Available Use% Mounted on
[2009-02-19 10::31:15] ** nyeates left the chat room.
[2009-02-19 10::31:38] teletype: looks like it's being confused by the output extending to 2 lines
[2009-02-19 10::31:45] csayers: thats what I thought
[2009-02-19 10::33:56] teletype: if you add a -P to your df command it should stop doing that
[2009-02-19 10::35:31] drtns: quick question... when I did training it was mentioned that for Linux etc that the recommended snmp ver was 2c but in the zProp's for Devices it's set to v1 I assume I just change it there and go up to 2c as recommened?
[2009-02-19 10::36:39] kells: BTW, there's an open ticket for the df -P thing
[2009-02-19 10::36:59] csayers: oh.. ok sorry
[2009-02-19 10::39:05] kells: Yeah, the v2c is good for larger values etc
[2009-02-19 10::47:43] malbon: so what's new in 2.3.3 ?
[2009-02-19 10::47:55] kells: Mostly just maintenance fixes
[2009-02-19 10::48:56] ** samo joined the chat room.
[2009-02-19 10::49:33] kells: Hmmm.... Oh yeah! We think (fingers crossed) that we may have finally fixed the numeric OID to name mapping issue that has been driving people crazy since 2.2.4
[2009-02-19 10::49:55] malbon: haha cool.
[2009-02-19 10::50:50] kells: There are zenhubworker fixes (VERY highly recommended) and then adding zenhubworkers should improve that situation muchly
[2009-02-19 10::52:50] malbon: we are running with 4 zenhubworkers right now, seems to be much better for responsiveness for us.
[2009-02-19 10::54:05] kells: There are some pretty important zenhubworkers fixes in 2.3.3
[2009-02-19 10::54:33] ** csayers left the chat room.
[2009-02-19 10::54:44] kells: There's an important fix for zencommand that with the zenhubworkers will make life much better.
[2009-02-19 10::55:11] malbon: kells: nope, no commands hardly at all.
[2009-02-19 10::55:57] kells: YMMV with the number of zenhubworkers. I've just had people ask "How far does that crank go?" and there are definitely diminishing returns with it.
[2009-02-19 10::56:49] cgibbons: is the crank gold plated?
[2009-02-19 10::56:58] malbon: I think in our case having 4 real CPU cores helps a lot. But indeed I agree with the YMMV, but it'd be nice if there was a standard test suite for sizing and performance. Maybe with version 3 or 4.
[2009-02-19 10::56:58] kells: Hmmm... Well, at least the zenhubworker fixes should make life a little better. There's a priority queue for dealing with lots of activity
[2009-02-19 10::57:14] malbon: is that patch 11791?
[2009-02-19 10::57:42] kells: Scalability testing is a biiig can of worms, and it will take a while for us to get that type of platform to be stable, reliable and etc etc
[2009-02-19 10::58:01] malbon: oh ok.
[2009-02-19 10::59:00] ** commarla left the chat room.
[2009-02-19 10::59:17] ** __ian__ left the chat room.
[2009-02-19 10::59:17] kells: Ummm.... Soon? Probably early next week
[2009-02-19 10::59:49] mrayzenoss: we're on RC2
[2009-02-19 11::00:17] malbon: ah, ok.
[2009-02-19 11::00:32] mrayzenoss: we've been trying to fix the stack installer on OpenSUSE 11
[2009-02-19 11::00:39] malbon: sounds good, I'll be applying that one pretty quickly.
[2009-02-19 11::00:53] mrayzenoss: yeah, it should hold everyone over until Blue Crab drops
[2009-02-19 11::01:19] malbon: Has anyone used Zenoss on Unbreakable? We looking at alternate OS support options.
[2009-02-19 11::03:11] mrayzenoss: I imagine it would work, I haven't heard of anyone using it, but I don't think it's very different from RHEL
[2009-02-19 11::03:53] malbon: indeed, it's a cheaper knock-off
[2009-02-19 11::06:03] mrayzenoss: well, we probably won't test it unless an Enterprise customer asks for it (wink wink)
[2009-02-19 11::06:18] kells: Oh dear....
[2009-02-19 11::06:22] mrayzenoss: heh
[2009-02-19 11::07:34] malbon: haha, well indeed. We may not go down that route, we are doing costings.
[2009-02-19 11::08:13] mrayzenoss: I know Novell is offering big discounts for RHEL->SLES converts, including support for RHEL while you transition
[2009-02-19 11::08:49] malbon: ah I didn't know that, but it does make perfect sense.
[2009-02-19 11::09:03] ** samo left the chat room.
[2009-02-19 11::10:02] mrayzenoss: I am curious about Unbreakable, if it's really any different from RHEL. I imagine it's a CentOS-like conversion with some tweaks for Oracle performance
[2009-02-19 11::10:31] ** x-spec-t joined the chat room.
[2009-02-19 11::10:32] malbon: yes, it is basically RHEL but with sueability provided by Oracle rather than Redhat
[2009-02-19 11::11:06] mrayzenoss: I guess you're a big Oracle shop?
[2009-02-19 11::11:50] ** Spec left the chat room.
[2009-02-19 11::12:02] ** mikl left the chat room.
[2009-02-19 11::12:05] malbon: none at all.
[2009-02-19 11::12:46] mrayzenoss: oh sure, I just figured most Unbreakable users would already be Oracle DB users
[2009-02-19 11::13:18] malbon: they sell it as a generic OS luckily.
[2009-02-19 11::14:01] mrayzenoss: it's picking up traction, the Barracuda author checked in some fixes last night
[2009-02-19 11::14:31] malbon: cool, can I add in a feature request?
[2009-02-19 11::14:33] mrayzenoss: I've seen people start bookmarking the pages in there
[2009-02-19 11::14:40] kells: In my experience, the Unbreakable (this is the Oracle rebranded RHEL, right?) was waaay behind the times in patches and in fixes. It's probably improved by now...
[2009-02-19 11::16:08] malbon: a 'click to build' system to build specific revs of zenpacks.
[2009-02-19 11::17:05] ** __ian__ joined the chat room.
[2009-02-19 11::17:42] mrayzenoss: Duly noted
[2009-02-19 11::18:09] ** snowgod left the chat room.
[2009-02-19 11::18:24] malbon: yeah, used that feature... liked it.
[2009-02-19 11::23:35] mrayzenoss: Anyone want to test OpenSUSE 11.1?
[2009-02-19 11::25:40] ** thibaud left the chat room.
[2009-02-19 11::26:15] ** thibaud joined the chat room.
[2009-02-19 11::27:20] malbon: gotta go, thanks folks.
[2009-02-19 11::28:53] mrayzenoss: thanks to everyone who showed up, this'll be posted on the IRC page soon
