Help with Nagios
 

Hello!
I have recently acquired a server that has Nagios running on it and i'm not sure what version, how can I find this out?

Also there was a nagios.log file that was located in /var/log that got deleted and now I can't seem to recreate that file. I assumed it would recreate itself when restarting Nagios, this was not the case.

Last question, does anyone know what version of linux they use in during the Red Hat certificate test.

Thank you and any help will be much appreciated.

check nagios web interface home page
OR
/path/nagios/bin/nagios -h
