You monitor GKE clusters in a Cloud Monitoring workspace and need to triage incidents quickly. What is the appropriate operational approach?

The correct approach leverages Cloud Monitoring's native capabilities for GKE. Predefined dashboards offer immediate visibility into common GKE metrics, allowing for quick incident triage. Once the issue is identified, you can add specific metrics to these dashboards for deeper analysis and create alert policies directly within Cloud Monitoring to be notified of future occurrences. The other options are less efficient or appropriate. Creating custom metrics and installing separate alerting software (option 2) introduces unnecessary complexity and management overhead when Cloud Monitoring already provides these features. Writing a shell script, publishing to Pub/Sub, exporting to BigQuery, and using Data Studio (option 3) is overly complex and introduces significant latency and maintenance for real-time incident triage. Creating a custom dashboard for each incident (option 4) is unsustainable and inefficient; predefined dashboards and targeted metric additions are more practical.
