Check the status of greenboot health checks

You can check the status of greenboot health checks before making changes to the system or while troubleshooting. By using helpful commands to verify that greenboot scripts have finished running.

Procedure

Check the current greenboot health check status by running the following command:
```
$ systemctl show --property=SubState --value greenboot-healthcheck.service
```
where:

start

Greenboot checks are still running.

exited

Checks have passed and greenboot has exited. Greenboot runs the scripts in the green.d directory when the system is in a healthy state.

failed

Checks have not passed. Greenboot runs the scripts in the red.d directory when the system is in this state and restarts the system.
Check the numerical exit code of the greenboot health check service by running the following command:
```
$ systemctl show --property=ExecMainStatus --value greenboot-healthcheck.service
```
An exit code of 0 means the health check succeeded. A non-zero exit code means the health check failed.
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
```
Example output
```
Boot Status is GREEN - Health Check SUCCESS
```
