Histogram metrics

Tracks request execution time and counts for applications, web services, and static files managed by GAS, using separate bucket sets to match each type’s typical latency profile.

Histograms are configured in the GAS configuration file (as.xcf) in the PROMETHEUS element.

The GAS uses different histogram buckets for applications, web services, and static-file requests. To learn why these buckets differ and how they help measure a range of response times, go to HISTOGRAM_BUCKETS
