Nagios Update

OK... Chris pointed out that I am a numpty... spotting that I hadn't installed a VRML plugin into my browser. Plugin installed, I can now view the 3D status map... not that it's very exciting!

I have also just found out why my icons were missing. For some reason they weren't in the website folder! This is very strange because I remember putting them there and I have even changed the permissions on them. :-S All fixed now though :-D

I spent an hour or two today splitting my config files into template-based versions. This was easy enough to do but it was very time consuming - I'm monitoring a lot of services and hosts! What this should mean, is that I can more easily add new hosts and service checks to existing hosts.

All that remains is to complete the NRPE_NT installation on the remaining servers and possibly passive SNMP trap checks for devices like the SAN and Citrix which don't respond to SNMP get commands.

Oh yeah... I need to fix the mail on that box so that it emails me properly ;-)

VPNs and Nagios

This last week, I have mostly been playing with the new VPN that CLEO have set up for me. After much argument, trying to tell them that the ACLs were wrong, they finally caved and admitted it!

Since then I have been playing with my Nagios box in the evenings - sad I know...

I have uninstalled the installation of Nagios that I installed using the package in Debian Unstable in favour of compiling it myself. I found that the installation structions documented this quite well and barring a couple of minor problems it went on painlessly. I only need to fix the icons for the hosts and the 3D status map now.

I have re-installed all my old config files successfully too and can now process 'external commands' successfully (the main reason for switching to the compiled version).

Tonight's forray into Nagios has involved the setup of NRPE_NT. This involves installing a service on my Windows Servers so that plugins can be run when the check_nrpe plugin on the Nagios box polls them. This has allowed me to monitor disk usage, memory usage and CPU utilisation... items that should prove quite handy!

My next task will involve the installation of NRPE_NT onto the remaining 11 boxes, fixing the problems with images and splitting my config files into neat little template-based ones ;-) Maybe a job for the weekend?

I'll also post something about my trip to Edinburgh soon :-D
