Understand exactly where time is spent.

P50/P95/P99 percentiles for every endpoint, span waterfall traces, and per-endpoint drill-downs. Know exactly what's slow and why.

Service facts

The dispatcher's sheet, per endpoint

How Traceway decides what counts as slow.

5signals, one score
An inverted apdex variant, error rate floor, P99 latency floor, client error floor, and volume error floor — combined into a 0-100 Impact Score.
3percentiles per endpoint
P50, P95, and P99 with throughput and error-rate breakdowns and historical trend comparison.
≤750 msapdex anchor
Good under 750 ms, tolerable to 1500 ms, bad above or on 5xx — override the slow threshold per endpoint.

Worst-first

If any signal is bad, the endpoint surfaces.

The Impact Score takes the max across all five indicators, so a single degraded signal can't hide inside an average. Performance dashboards are included in every plan — and in the MIT build on your own metal.

On this line

One score. Five signals. Zero guesswork.

Per-endpoint analytics at a glance, and the full trace behind any single request when you need it.

Endpoint introspection

Detailed request/response payloads and custom context tags — the exact state of your application for every trace, not just aggregates.

Percentile analytics

Quickly see which routes are fast and which need attention, with per-endpoint slow-threshold overrides.

Span waterfall

Break every request into its component operations with precise timing for each span.

Apdex on your terms

A deliberate knob, so /api/health and /api/checkout are judged on their own terms.

Housekeeping

Server metrics moved.

CPU, memory, goroutines, and GC live on the Metrics page now. Performance stays focused on latency, percentiles, and waterfall span analysis.
