Without this, gauges starting at 0 that never change (e.g. `jobq_job_count`) would be invisible in Prometheus. +- **I/O latency fix**: `io_latency_sampler` emits unconditionally on first sample, then applies the 10 ms threshold.

This can cause two problems in the validation environment: + +1. **Initial-zero gauges** — if a gauge value is 0 from startup and never changes, the gauge would never emit. To address this, `StatsDGaugeImpl` initializes `m_dirty = true`, ensuring the first flush always emits the initial value. +2. **Stale gauges** — once a gauge stabilizes (e.g., peer count stays at 1), it stops emitting new data points. Prometheus marks it stale after ~5 minutes. The validation script uses the Prometheus `/api/v1/series` endpoint instead of instant queries to catch such gauges. diff --git a/docker/telemetry/workload/benchmark-results/.gitkeep b/docker/telemetry/workload/benchmark-results/.gitkeep new file mode 100644 index 0000000000..e69de29bb2 diff --git a/docker/telemetry/workload/benchmark.sh b/docker/telemetry/workload/benchmark.sh new file mode 100755 index 0000000000..6be60e6428 --- /dev/null +++ b/docker/telemetry/workload/benchmark.sh @@ -0,0 +1,379 @@ +#!/usr/bin/env bash +# benchmark.sh — Performance benchmark for rippled telemetry overhead. +# +# Runs two identical workloads against a rippled cluster: +# 1.
