To analyze various failures, freezes or simply incorrect behavior of the controller, a detailed archive of system logs and configuration files is needed.

A convenient tool for collecting such an archive is the sosreport package.

To use it:

* install sosreport and sysstat in advance:

sudo apt-get install sosreport sysstat

* after a failure, as soon as possible, we collect the archive:

sudo sosreport -a

We transfer the collected archive for analysis, for example, via tech support forum.
