linuxsystemdsystemctl

getting uptime or downtime of systemd process using systemctl?

like using systemctl is-active <servicename> gives is if service is active or failed then is it possible to get the uptime or downtime of the systemd service all using systemctl ?

time systemctl status kdm|cat
* kdm.service - LSB: X display manager for KDE
   Loaded: loaded (/etc/init.d/kdm; generated; vendor preset: enabled)
   Active: active (exited) since Wed 2017-06-21 12:03:26 CEST; 1h 42min ago
     Docs: man:systemd-sysv-generator(8)
    Tasks: 0 (limit: 4915)
   CGroup: /system.slice/kdm.service

is it possible to get the 1h 42min using systemctl

Solution

  • Using systemctl's property WatchdogTimestamp
