/etc/init.d/stackdriver-agent status /etc/init.d/stackdriver-extractor statusWith both services running, you should now be able to see a "Processes" tab on your instance details page that lists information on the processes that are running on your instance.
You can also use this information to set up an alerting policy for a resource or group of resources to alert you when a process is not running. To do this, create an alerting policy with a condition type of process health. After selecting the instance or instances you wish to alert on, you can provide a process name, required number of processes and the user that should be running the process. If this condition is violated, you can choose to be notified via the same channels as for any other Stackdriver alerting policy.
