Howto avoid journald entry for one program?

  • 772

On my Ubuntu-MATE Clevo laptop there is the program N151ZU-fan-controller that logging a message 2 times by second.

I filtered it in rsyslog configuration in /etc/rsyslog.d/10-N151ZU-fan-controller.conf with line :programname, contains, "N151ZU-fan-controller" stop

But I could not find howto filter it's logs in journald (systemd-journald) ? 2 lines by second take much volume on disk ...

Thanks

log systemd-journald

    I found how to redirect stdout to null with option StandardOutput in service configuration file.

    Like 

    # /etc/systemd/system/N151ZU-fan-controller.service
...
[Service]
...
StandardOutput=null
...
