Question

Your team runs a fleet of Compute Engine VMs hosting a memory-intensive application. In Cloud Monitoring you can see CPU utilization for each VM, but you cannot find any memory usage metrics to build a dashboard chart. What must you do to collect and visualize per-VM memory utilization?

Accepted Answer

Install the Ops Agent on the VMs so that memory metrics are collected and reported to Cloud Monitoring.

Answer

Enable the Compute Engine API in the project to expose additional built-in memory metrics.

Answer

Create a log-based metric that parses memory values from the serial console output.

Answer

Grant the Monitoring Viewer role to the VM service account so it can publish memory data.
