And also is there a way to report alert (via nrpe again) if there are some keyword ,eg if there is something like 'error 'the return should be critical ,like that

It'll probably be quicker to search: https://www.google.com/search?q=nagios+ ... 8&oe=utf-8

A few examples:

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.

thanks a lot all...
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 ?

[rmank]

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.
