Here you will see the available log files. For more information please see the Developer article on logs. To change where, when and how logs can be stored and monitored, please see the Debugging tab in Site configuration.
You will see here a list of any available log files, broken into two categories.
The first are the system logs. These are automatically made by Jomres and allow you to closely analyse many of the things that Jomres is doing.
The second are the individual Error logs that might have been triggered due to a problem or mis-configuration. Note, only the last two week's worth of these files are shown.
Assuming that you've done as recommended and moved the logging location above the root directory, you will not be able to access these log files directly. Instead you will need to click the name of the log in this page.
