Google Monitoring - How to retrieve VM name from instance ID

[tacoma50]

I have this metric selected for my apache monitor:  VM Instance - workload/apache.requests

When the alert is triggered, I receive this info in the email sent to me:
   metric : workload.googleapis.com/apache.requests
   instance_id : 2345xxxxxx2345
   instrumentation_source : agent.googleapis.com/apache
   server_name : 127.0.0.1
   zone : us-xxxxxx

While the instance-ID can identify which apache server was alerting, the VM-name is much more obvious to user than the instance-id.

When setting up the the monitor we are able to pass along notes in the alert email via the POLICY DOCUMENTATION text field.   How can I retrieve  the VM instance NAME from the instance-ID so I can display the VM name in the POLICY DOCUMENTATION text field emailed to the user? .
