Fleet — App Overview

p99 request latency for the sample HTTP service across a label-selected fleet, from http_request_duration_seconds histogram buckets. Filter with the dashboard_instance variable. Part of the oyatrino-o11y-labs reference stack.

Fleet App Overview

A starter dashboard for a fleet of HTTP services. It expects the conventional http_request_duration_seconds histogram, so it works with any service instrumented via a standard Prometheus client library — no framework assumptions.

Panels

  • p99 request latency: histogram_quantile(0.99, sum by (le, instance)(rate(http_request_duration_seconds_bucket[5m])))

Requirements

  • Your service exposes a Prometheus /metrics endpoint with an http_request_duration_seconds histogram.

  • Prometheus scrapes it with a dashboard_instance label on the target.

Variables

  • datasource: Prometheus data source.
  • dashboard_instance : selects the fleet member(s). Extend with request-rate and error-rate panels (http_requests_total) as needed.
