Question

Your team runs a customer-facing service on Compute Engine behind an HTTP(S) load balancer. Customers complain about occasional slow responses, but the average latency shown on your existing dashboard looks fine. You need to investigate whether a small percentage of requests are experiencing high latency. In Cloud Monitoring Metrics Explorer, what should you do to surface this behavior?

Accepted Answer

Chart the load balancer total latency metric and apply a 95th percentile aligner/reducer to view tail latency

Answer

Chart the load balancer request count metric and apply a sum aggregation across all backends

Answer

Chart the load balancer latency metric and apply a mean aligner grouped by backend zone

Answer

Create an uptime check against the load balancer frontend and view its latency graph
