Nagios Core Help

[chuck112]

Long story short, which I know Ill get a lot of questions which I need. I have nagios up and going I have many servers on my service tab and see a lot of SSL handshakes not working... so im just going out on a limb and saying its cause the plugins and the NRPE are all old from the core i just installed.... I have just resurected this project so they started then stopped so I am getting some greens and some fails...

So i went in and reinstalled the plugin and nrpe cause I could not find an easy button to update all the servers. now still getting the same handshake issue.

Ideas?

Thanks in advance.

Have you set the "allowed_hosts" directive on each of the clients nrpe.cfg to the ip of your nagios server? You can try sunning a check against one of the broken remote hosts and then check that host's system messages for nrpe errors/output:

Code: Select all

tail -50 /var/log/messages

Additionally, please look at the following document, it will be a bit more verbose than this post:

Okay found a new issue


Error: Could not stat() command file '/usr/local/nagios/var/rw/nagios.cmd'!

The external command file may be missing, Nagios may not be running, and/or Nagios may not be checking external commands.

An error occurred while attempting to commit your command for processing.

I get this when I try to put a service on hold. any ideas on how to fix this?

Is nagios running?

Code: Select all

service nagios status

What is the output of the following commands?

Code: Select all

ls -lad /usr/local/nagios/var/rw
ls -la /usr/local/nagios/var/rw
grep nag /etc/group

Note: Modify the paths if they are different on your system.
