If there is no compelling reason - use the latest - centos 6.

I used the Fedora instructions to install Nagios on CentOS myself. It has been a while since I did it, though. The only snag I remember having was forgetting to install some packages like openssl-devel and net-snmp-devel before compiling the plug-ins.

The problem is that there's a limited way of configuring Nagios for a particular setup, so it's always entirely possible that whoever you *think* is stealing configuration from you has actually read the nagios docs for 15-30 minutes and then figured out how to do it themselves. It's not exactly rocket science, and a nagios config isn't a super-fast cryptographically secure hash algorithm that you (sometimes) need to jealously protect.

[Nagios-users] Dependencies
Hi,
I am trying to get some of the dependency stuff working in Nagios.
I have a very simple system:
Machine A Router B . Internet machine C
I use the following to show the relationship:
define host{
use linux-server
host_name A
parents B
}
1) The 'status map' shows nagios as being somehow between A B, whereas it is
on A (ie it runs on A).
Is there a way that I can tell nagios that it is on A ?
2) I check that DNS is still working thus:
define service{
use local-service
host_name A
service_description DNS Access
check_command check_dns
}
How do I say that this depends on B ? ... I don't want warnings just because
the router is dead.
I also check (twice/day) that the clock on A is accurate, that will only
work if NTP works, ie
also depends on B, but is very much tied to A.
TIA

Re: [Nagios-users] execute command as root user

To be specific: Tomcat is giving up work now and then on this machine, I can trap it, and need to restart it. Normally I do this by /etc/init.d/tomcat restart -- but I need to be root for this, so nagios cannot do this automatically for me, because it runs as nagios user. What is the best way to approach this ? Changing the owner of the tomcat-related startup files so that nagios can do it ? Writing a file on-critical-error and restarting tomcat (as a cron-job), whenever that file exists ? Something else ? Use the 'sudo' command. Alternately: write a short program in C, that is setuid root, that execs the init script.

[Nagios-users] Sharing local/remote machine .cfg
I am relatively new to Nagios, I am setting up a group of Linux machines that all send reports to a central monitoring one with nsca. I have a separate .cfg file for each machine, I would like to share this file between remote and central machines - so that if I change anything I just copy it over. One change that *is* needed is the value of active_checks_enabled - which is zero on the central box and one on the remote. I tried something like this in a 'define service': active_checks_enabled $USER11$ and elsewhere had: $USER11$=1 or $USER11$=0 as appropriate for the machine. This does not work. Why ? and is there a way of achieving what I want to do ?
