Question

Your operations team manages hundreds of Compute Engine VMs across several environments. VMs are tagged with a label 'env' set to values like 'prod', 'staging', or 'dev'. You want a single Cloud Monitoring construct that automatically includes any new VM tagged 'env:prod' so dashboards and alerting policies always reflect the current production fleet without manual updates. What should you configure?

Accepted Answer

Create a Monitoring group with a membership criterion that matches the label 'env = prod'.

Answer

Create a static list of resource names in each alerting policy and update it whenever a VM is added.

Answer

Create a log-based metric filtered on the 'env' label and build the dashboard from that metric.

Answer

Create separate custom dashboards per VM and use dashboard folders to organize them.
