System Logging
|
|
==============
|
|
|
|
When troubleshooting problems with your firewall, it is very likely you have to check
|
|
the logs available on your system. In the UI of OPNsense, the log files are generally grouped
|
|
with the settings of the component they belong to. The log files can be found here:

Circular Log
|
|
------------
|
|
|
|
Most of the core features log to circular log files so they will not grow bigger
|
|
than a predefined size. You can tune this value via **System->Settings->Logging**.
|
|
There, you can also disable the writing of logs to disk or reset them all.
|
|
|
|
You can view the contents via CLI with:
|
|
|
|
.. code-block:: sh
|
|
|
|
clog /path/to/log
|
|
|
|
or follow the contents via:
|
|
|
|
.. code-block:: sh
|
|
|
|
clog -f /path/to/log
|
|
|
|

|
|
Syslog
|
|
------
|
|
|
|
In **System->Settings->Logging** you can also set a remote log server to send
|
|
your log files to. Choose a **Source Address** if needed and fill in the **Remote Syslog Server** field.
|
|
Via **Remote Syslog Contents** you can choose which kind of logs to send.

Plugin Logs
|
|
-----------
|
|
|
|
Many plugins have their own logs. In the UI, they are grouped with the settings of that plugin.
|
|
They mostly log to /var/log/ in text format, so you can view or follow them with *tail*.
