PCDOE Implementing service monitoring strategies Practice Question
A DevOps engineer needs to verify if a load balancer's health check is behaving normally by examining historical trends. Where should they look?
⚠ Common exam trap
It's easy for candidates to confuse Cloud Logging (which shows raw events) with Cloud Monitoring Metrics (which shows aggregated trends), leading them to choose Cloud Logging or the health check page when the question explicitly asks for historical trends.

Correct answer & explanation
✓
Cloud Monitoring Metrics Explorer
Cloud Monitoring Metrics Explorer is the correct place to examine historical trends of a load balancer's health check because it provides time-series metrics such as `https/backend_request_count`, `https/backend_latencies`, and health check probe success/failure counts. These metrics can be queried over custom time ranges and aggregated to detect anomalies or degradation patterns, which is exactly what the question asks for — verifying historical trends of health check behavior.
