Nagios Support Forum

What do these load balancers use for their health checks? Might we just be able to have Nagios monitor those health check targets instead? We have an "internal" home grown monitoring tool that checks the health of the service, completely, but not an individual node like a global site sele...

They're virtual IP's for load balancing. But regardless of that fact, no we can't reach within our subnet, at all. So anything we can't get NRPE installed on, such as a VIP, we can't do any checks on. Which all they are is ping checks anyways, since they are just load balancing IPs.

I don't think your post requires a TL;DR - not that bad! To clarify, why are the host/services reporting down? Do you have a firewall / ACL's applied? Nagios will need a route directly to each host you'd like to check. An alternative, is using check_nrpe at a remote site, and having your checks run...

So we're running into an issue that isn't likely going to be fixed soon....or ever that limits us to reach certain hosts within our subnet. This happens in multiple sites that we have. So basically what that means is we have services/hosts reporting down when in reality they aren't. However, I can r...

so the host I was working on ended up having a WHOLE host of issues due to one our guys setting it up wrong. UGH! Fortunately he's no longer with us. It was setup under the wrong group in spacewalk and had all kinds of conflicting packages that it shouldn't have had. Set it up under the right group ...

To install NRPE from source: NRPE dependencies: openssl openssl-devel gcc xinetd install NRPE on remote host: yum install openssl openssl-devel gcc xinetd useradd nagios && passwd nagios cd /tmp wget http://sourceforge.net/projects/nagios/files/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz tar zxvf n...

says I'm missing a bunch of other stuff( gcc, glc.exe....think that's it). I went in to spacewalk and tried to find the previous version and there's no x86 packages for the previous glibc version available in spacewalk anymore.....ugh. I found a way around doing a yum install of the plugins and nrpe...

So I commented out the prereqs portion and it made it a little further then errored out. Don't think that's the best way to go about it.

Can you delete the glibc-common portion out that yum command in that script? Otherwise you could 'touch installed.prereqs' , but if there are dependencies you're missing after that, the deleting option may be better. hmmm opened up the script and removed the glibc and gcc in the 1-preqs file. Same ...

Should have added this is using the install script from nagios. So not using yum as our repos are centrally managed via spacewalk and since there are no nagios repos in there it'll say "none available". So I didn't put together this script.
