To troubleshoot issues with the
fail2ban module, run the
python.d.plugin with the debug option enabled. The
output will give you the output of the data collection job or error messages on why the collector isn't working.
First, navigate to your plugins directory, usually they are located under
/usr/libexec/netdata/plugins.d/. If that's
not the case on your system, open
netdata.conf and look for the setting
plugins directory. Once you're in the
plugin's directory, switch to the
sudo su -s /bin/bash netdata
Now you can manually run the
fail2ban module in debug mode:
./python.d.plugin fail2ban debug trace
