Revision history [back]

Hello sailors,

i want to analyse actions of a specific process, and thought that i could maybe make it with the journalctl command.
Firstly, I wanted to represent myself what could give the command back, using different options.
Whatever I may use for an option, the command gives back "no journal files where found".

Is that normal that journalctl bring "no journal files where found" back?
Should i activate something first for having results?
Is that that specific to sfos ?
Would be nice if someone could help giving some small skills for this command please?

Thank you very much in advance for any information about it.
Have a nice sail

PS: For my process analyse, may the following command journalctl _SYSTEMD_UNIT=process_name _PID=nnn be interesting ?
