Fix GCP Cloud Run Run Monitoring Errors
When working with GCP Cloud Run, you may encounter a configuration error that prevents your deployment from working. This guide explains the most common mistake with run monitoring and shows the exact fix.
A Common Mistake
Deploying a Cloud Run service without setting up monitoring dashboards or alerts, so service degradation goes unnoticed until users report it.
The incorrect command:
gcloud run deploy my-service --image=gcr.io/my-project/my-image
Error output:
Deployed.
No dashboards, no alerts.
The service starts returning 500 errors due to a database connection leak. Nobody notices for 6 hours. Users report the issue via email. Customer confidence is damaged.
The Correct Approach
The right way to configure run monitoring in GCP Cloud Run:
gcloud run deploy my-service --image=gcr.io/my-project/my-image && gcloud monitoring dashboards create --config-from-file=dashboard.json
# dashboard.json: latency, error rate, CPU, memory, instances, billings
# Also set up alerts:
gcloud alpha monitoring policies create --policy-from-file=alert.json
Successful result:
Deployed with monitoring.
When error rate exceeds 1%:
Alert fires, sends email/SMS/PagerDuty notification.
Team responds within 5 minutes. Issue is resolved in 15 minutes.
How to Prevent This
Create dashboards for latency, error rate, CPU, memory, instance count, and concurrency. Set up alerting policies for error rate > 1%, latency > p99 threshold, instance count > 80% max. Use Cloud Monitoring's Cloud Run dashboard template. Set up budget alerts for cost monitoring.
