The links that
@gormank have shared are a good place to start, but I do need to mention that Nagios Logserver is a better tool for the job:
https://www.nagios.com/products/nagios-log-server/
We built it specifically to solve this problem, and monitoring logs with it is going to be much simpler in the long run.

rmank, you got help from 2 people already but I will post my reply anyway.
You can use the following two plugins:
https://github.com/pld-linux/monitoring ... _exists.sh
https://exchange.nagios.org/directory/P ... nt/details
Here's a couple of examples of plugins, run locally:
Code: Select all
./check_file_exists.sh /usr/local/nagios/var/nagios.log
OK: /usr/local/nagios/var/nagios.log EXISTS :: [1454392800] LOG ROTATION: DAILY
[1454392800] LOG VERSION: 2.0
Code: Select all
./check_file_content.pl -f /usr/local/nagios/etc/nagios.cfg -i "enable_notifications=0" -n 0
OK for /usr/local/nagios/etc/nagios.cfg (1 found)
You can call these scripts remotely via check_nrpe. Let us know if you are having any more questions/issues.

lmiltchev ..I tried locally it working well ,should I need to declare this a command for both the nrpe config ,on the nagios server and the clients ?

No problem! Glad to see you made it past the firewall.
I'll close this out now, but feel free to open a new thread if you ever need assistance in the future.
