How to monitor a dynamically changing Log file

[deek]

Hi ,
I have got to monitor a Log file and search for a string . But the problem is that the Log file is dynamic in nature . I tried using regular expression , but its not working .
Ill attach the command line I have used .

Command View :
$USER1$/check_nrpe -H $HOSTADDRESS$ -u -t 60 -c $ARG1$ $ARG2$

$ARG1$ : check_logfile_WinTerm

Screenshot of the Log file path -

Hi @deek,

I'm not too familiar with this plugin, check_logfile_WinTerm. Can you provide a link to the plugin page?

That said, Nagios XI is not really designed for log file monitoring, we have a separate product for that called Nagios Log Server. We even offer a free version for small environments.

https://www.nagios.com/products/nagios-log-server/

Let me know if that would be an option for you.

Hi ,
Actually check_logfile_WinTerm is not a plugin . I had defined this term in the nsclient++ file under [/settings/external scripts/scripts] . So I mentioned in the $ARG1$ .

Ill check the Nagios log server capabilities . Thank you

Hi ,
Actually we wont be using Nagios Log server because we already using Splunk to monitor the logs .

But I wanted to know if there is a way to monitor dynamically changing log files in Nagios XI .

If you change your logfile line to this, does it work?

Code: Select all

logfile => 'I:\log\cot\cot.$CL_DATE_MM$.$CL_DATE_DD$'

You may want to create a I:\temp folder and change your $protocolsdir and $seekfilesdir to it and see if that resolves the permissions issue.
