Yes there is!

Check_SNMP. Fuck me though, working with the snmpwalk output isnt the most enjoyable task. Doco on common (and useful) MIBs seems a bit thin on the ground which makes things a bit difficult...

Wondering if anyone's ever used the Centreon (http://www.centreon.com/) frontend for nagios?

Seems to have most of what's necessary for managing configuration and certainly looks pretty, though either I'm going slowly insane, or there's nowhere in the interface to work with existing services - plenty of places you can create new ones, or work with templates, but unless a service is already assoicated with a host or hostgroup, there's no way to actually see it, which is sorta necessary to assoicate it with a host or group in the first place...

That does look awsome, i might give it a test. does any one know of a good vm appliance that takes care of setup and install?

While it doesn't come with Nagios, it's fairly easy to install once you've got nagios setup from source or package. Nagios runs happily in the background (meaning you can still use the default nagios interface, and configuration if you keep a seperate config dir for your handrolled stuff), centreon collects data via NDO, writes config out to a specified dir and reloads nagios as required.

The Centron installer seems to work OK - asks a lot of questions, but if you answer them right, you're good to go

Upgrade process from 2.0.2 to 2.1.2 was very painless, though bigger jumps may bring problems.

Just wondering if someone can help me figure out what is going on with my nagios install.

go the system up and going, now im trying to monitor one of our windows boxes.

I've installed NSClient++ on the client, and gone through and edited the ini file correctly (from what I could find its done right - but there could be something I've missed).

When I've added the host to Nagios, it sees the host but won't get any service information. All I get is the error 'Connection refused
could not fetch information from server'

Spingo · 12th October 2009, 9:41 AM

Sounds like a connectivity issue - check that the NSClient++ service is running, and ensure that the port that it's bound to (or the service) is not being blocked by Windows Firewall.

jsp1511 · 12th October 2009, 9:56 AM

NSClient++ service is running, windows firewall is disabled on the box im trying to monitor

no firewalls in between as they are hosts on the same lan and subnet

also disabled SEP incase that was causing any issues

SpudBoy · 12th October 2009, 9:58 AM

is it just me, or doesnt the NSClient open its ports up on the windows firewall when its installed/service is started?

edit:
it sounds to me that either the nsclient didnt install correctly, or the ini file is borked.
double check the ini file, and then do a complete removal on the client, and reinstall.

jsp1511 · 12th October 2009, 10:29 AM

ok did the un-install and reinstall of the nsclient++ and that doesn't seem to have done much

when i run the nsclient++.exe /test from a cmd i get the following:

looks like it *should* be running.

though (its a long shot, but might help) have you got the correct permissions of the nagios folder?

jsp1511 · 12th October 2009, 10:36 AM

I take it you are talking about the client?

Yeah logged in under an admin account so there is no issues there

SpudBoy · 12th October 2009, 10:39 AM

yeh i was.

hmm.. this one looks a bit wierd.

the only thing i can really think of at the moment that could cause this (after checking the others) is if the network settings have not been configured correctly.

(i.e. subnets / gateways / routing etc)

jsp1511 · 12th October 2009, 10:47 AM

hmm i don't think its a network issue

both hosts are on the same physical network/subnet (ones a VM in ESX and the other is a physical box)

both can ping through to each other without any problems

might try monitoring another host to see if its an issue with that one particular host

edit: also what port should I be using??? 1248 or 12489?

I think 1248 was originaly the default for NSClient, though I've also found it's sometimes already in use on windows servers. Solution might be to pick another port, and make sure the same port is specified in the check command.

jsp1511 · 12th October 2009, 7:10 PM

tried it with both ports and a second host but neither seemed to work

but while screwing around wtih configs i found where the port is set in Nagios and confrimed its right

im guessing I can just use SNMP if i wanted to? (would prefer to as we have snmp strings in place for other things)

the only other issue I have atm is monitoring routers. I've installed mrtg and recompiled the plugins, but nagios is telling me it can't write to the logs files to record bandwidth (can't get the exact error right now cause im home from work
)

any ideas?
