Monitor Log file of unix server using Nagios core

Postby Srinija544 » Tue Jul 02, 2019 12:05 am

Hi All,

We have a new requirement to monitor a log file named: server.log and previous file: server.log.2019.07.01 in unix server.

Here we have two complications:

Monitor a running file: server.log(present day - 2019.0.02)
Monitor the previous day's file: server.log.2019.07.01

We have to monitor for a pattern like "ERRORS" in both the present and previous log files.
Please find the attached plugin script which we are using for this log file monitoring.
Please check the below command which we have in our commands.cfg:

define command{
command_name check_log_dc1uat163_oldone
command_line $USER2$/check_log $ARG1$ $ARG2$ $ARG3$
we have configured this by using this check command:

check_command check_log_dc1uat163_oldone!-F /apps/wildfly-11.0.0/standalone/log/server.log -O /apps/wildfly-11.0.0/standalone/log/server.log.2019-05-20 -q "ERROR"

But we got an error like this:

Log check error: Log file /apps/wildfly-11.0.0/standalone/log/server.log does not exist!


Please help me how this error can be resolved.

Thanks & Regards,

Does the nagios user have permissions to read this file?

Code: Select all
su nagios -c "tail /apps/wildfly-11.0.0/standalone/log/server.log"
