# Logs

This section will explain how to check the XOA logs, and use them to detect issues.

# From the web interface

Go into Settings/Logs view.


All XOA logs are stored in /var/log/syslog (on the XO Appliance).

To filter only what you need, you can use journalctl. Below is an example to filter only logs for xo-server:

$ journalctl -u xo-server -f -n 50

This will return the 50 last lines and tail the file. If you have an error message in your application, start this command and try to reproduce the issue. You'll see clearly what the problem is.

You can also filter for the updater program:

$ journalctl -u xoa-updater -f -n 50
