Check GUI log

When you get error on the GUI:

We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.

or something else is not working (e.g Graphs), you need to check RoR log. It has info what is wrong. . It can be done accessing file /home/mor/log/production.log.

Starting from MOR v0.5.0.5 it is possible to do that online using address http://<YOUR IP>/mor/debug/show_log.php.

It shows last 100 lines (usually it is enough) to find the cause of the problem.

Errors

You can get:

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 48372783 bytes) in /home/mor/public/debug/show_log.php on line 8

That means file is too huge. Login to server over SSH and do:

cp /home/mor/log/test.log /home/mor/log/production.log
