SoS report¶
SoS is an extensible, portable, support data collection tool primarily aimed at Linux distributions and other UNIX-like operating systems.
You can use the built-in version of SoS, or retrieve the latest version from GitHub.

Use built-in SoS (recommended)¶
Charmed PostgreSQL shipped with built-in SoS reporting tool. You can use it to collect logs on a specific unit or multiple units at once.
Collect logs on one unit¶
To generate the troubleshooting report archiving all logs simply call sos report inside the relevant Juju unit:
juju ssh postgresql/0
> sudo sos report -o system,systemd,snap,charmed_postgresql --low-priority
As a result, the archive will all logs will be generated and can be shared with your support representative:

...
Use juju scp to copy logs from Juju unit to localhost:
juju scp postgresql/0:/tmp/sosreport-juju-d4c067-1-2025-04-07-chdmwlz.tar.xz .
Example output
juju ssh postgresql/0

Collect logs from several units¶
The sos tool allows you to collect logs from several Juju units (replace <UNIT_A/B/…> labels with proper Juju unit like postgresql/0).
Run the following command from outside the Juju units:
sos collect --cluster-type juju --no-local -c "juju.units=<UNIT_A>,<UNIT_B>,<...>" --batch -o system,systemd,snap,charmed_postgresql --low-priority
Use the latest sos plugins from Git¶
The latest version of sos plugins can be retrieved from Git easily:
git clone https://github.com/sosreport/sos.git
cd sos
sudo ./bin/sos report -a
The output will be the same to the example above providing archive with all logs as above:
