5.3. Checking the status of greenboot health checks

Procedure

• To see a report of health check status, use the following command:

  $ systemctl show --property=SubState --value greenboot-healthcheck.service

  • An output of start means that greenboot checks are still running.
  • An output of exited means that checks have passed and greenboot has exited. Greenboot runs the scripts in the green.d directory when the system is a healthy state.
  • An output of failed means that checks have not passed. Greenboot runs the scripts in red.d directory when the system is in this state and might restart the system.

• To see a report showing the numerical exit code of the service where 0 means success and non-zero values mean a failure occurred, use the following command:

  $ systemctl show --property=ExecMainStatus --value greenboot-healthcheck.service

• To see a report showing a message about boot status, such as Boot Status is GREEN - Health Check SUCCESS, use the following command:

  $ cat /run/motd.d/boot-status
