gce/High Vm Cpu Utilization

Evaluates the CPU of a VM for high utilization that might indicate performance issues.

Product: Compute Engine
Step Type: AUTOMATED STEP

Description

This step determines whether the CPU utilization of the VM exceeds a predefined threshold, indicating potential performance degradation. It utilizes metrics from the Ops Agent if installed, or hypervisor-visible metrics as a fallback, to accurately assess CPU performance and identify any issues requiring attention.

Failure Reason

CPU utilization on this VM has surpassed recommended operational levels, which may affect its performance and SSH connectivity.

Failure Remediation

Excessive CPU usage can lead to performance bottlenecks. Consider resizing the VM to a more powerful machine type with higher CPU capabilities. Detailed instructions for resizing and restarting VMs are available here:

Resizing a VM: https://cloud.google.com/compute/docs/instances/changing-machine-type-of-stopped-instance#gcloud Additionally, use the GCE observability metrics for an in-depth analysis to pinpoint high-usage processes: https://cloud.google.com/compute/docs/instances/observe-monitor-vms#access_vm_observability_metrics https://cloud.google.com/compute/docs/instances/observe-monitor-vms#process_utilization

Alternatively, you can connect via serial console if SSH is unvailable to stop offending processes https://cloud.google.com/compute/docs/troubleshooting/troubleshooting-using-serial-console.

Success Reason

This VM currently has CPU utilization within the optimal range, indicating healthy performance.
