You can access key metrics for your Cloud Run serverless containerized workloads within the Cloud Run UI or Google's dedicated observability tool, Cloud Monitoring. Cloud Monitoring automatically collects metrics from different components of Google Cloud-hosted applications and services, separating them into monitored resource types with contextual labels to help identify specific issues. The two main monitored resource types in Cloud Run are Cloud Run Revision and Cloud Run Job, each with their own set of dimensions or labels that facilitate troubleshooting by pinpointing exactly where an issue is occurring. By viewing metrics within the Cloud Run UI or Cloud Monitoring, you can quickly see how your revisions and jobs are performing, view detailed logs and traces to identify bottlenecks and optimize performance, and roll back to a previous revision if needed. Additionally, you can collect and visualize metric types for Cloud Run monitored resources using Cloud Monitoring, and view service request traces to get an even deeper look at your application's performance.
