 OSService checks if an OS service is running on the host. OSService checks support Windows services on Windows hosts or SystemD services on Unix hosts. The check logs the service as `healthy` if it is running. If the service is not running, the status is logged as `critical`. All other results are logged with `warning`. A `warning` status indicates that the check is not reliable because an issue is preventing it from determining the health of the service.
