= Testing a workload health check script

[role="_abstract"]
You can look at the output of the greenboot workload health check script to see how it works. While the output varies with the host system type, the example outputs for {op-system-base-full} system types are included for reference only.


.Prerequisites

* You have root access.
* You installed a workload.
* You created a health check script for the workload.
* The {microshift-short} service is enabled.

.Procedure

. To test that greenboot is running a health check script file, reboot the host by running the following command:
+
[source,terminal]
----
$ sudo reboot
----

. Examine the output of greenboot health checks by running the following command:
+
[source,terminal]
----
$ sudo journalctl -o cat -u greenboot-healthcheck.service
----
+
[NOTE]
====
{microshift-short} core service health checks run before the workload health checks.
====
+
.Example output for an {op-system-image} system
