Sum rate
Calculate the rate of successful HTTP requests by method and route.
`otel-demo-metrics`:`http.server.request.duration`
| where `axiom.histogram` == "count"
| where `http.response.status_code` < 400
| align to 5m using prom::rate
| group by `http.request.method`, `http.route` using sum
Histogram
Calculate the 90th and 99th percentile HTTP request durations by service.
`otel-demo-metrics`:`http.server.request.duration`
| where `http.response.status_code` < 400
| bucket by `service.name` to 5m using interpolate_delta_histogram(0.90, 0.99)
Cumulative histogram
interpolate_cumulative_histogram works on histogram metrics using cumulative temporality. interpolate_delta_histogram works on histogram metrics using delta temporality.
`otel-demo-metrics`:`http.server.request.duration`
| where `http.response.status_code` < 400
| bucket by `http.request.method`, `http.route` to 5m using interpolate_cumulative_histogram(rate, 0.90, 0.99)
Compute
Compute error rate
Calculate the fraction of HTTP requests returning 5xx errors.

Service Level Objectives (SLO)
SLO compliance over time
Calculate the fraction of time JVM CPU utilization across checkout and payment services stays below 80% over a 7-day window.

SLO histogram
Calculate the fraction of requests completing within the 400ms latency SLO target, measured weekly.
`otel-demo-metrics`:`http.server.request.duration`
| bucket to 5m using interpolate_delta_histogram(0.99)
| map is::lt(0.4)
