Reading OTRS logs on CentOS

[davidbann]

Hi there,

I am very new to the Linux world - we recently migrated from a Windows environment to CentOS 7. I am researched what I can about the logs in CentOS and the best I have found is to use the journalctl command to read the system logs, although it shows a lot more than I would like to see...

Are there any tips for a noob on CentOS on what logs to look at and tricks to show only what is relevant to OTRS, including logs for cron jobs, and email logs?

Thanks

You can watch the syslog with

Code: Select all

less +F /var/log/messages

Thanks reneeb - very useful

Also use the system logs under the admin tab in the webinterface. I'm not getting everything in /var/log/messages, only mention of new sessions.

That's weird. Do you use Syslog for logging or your own file? If you use your own logfile, you should "less +F" this file... There is one problem with the system log in the admin area of OTRS: For each log entry it shows only the first line. If a log entry has several lines (e.g. a "dump" of a Perl datastructure) you get no information about the issue.

Thanks for the hints, I was using my own file, but I changed to because I was not getting anything in the syslog.
At least I now know the webinterface has less info than the console.
