Users say it's slow, average OK Response time scatter p99 ÷ median
Need release yes/no SLO gauges + Apdex SLO verdict, error %
Error rate > 0 Error sunburst errors by label + status
Flaky / inconsistent IQR outlier scatter CV, outliers beyond IQR
Capacity headroom RT vs throughput req/s at knee, p90 at plateau

Frequently Asked Questions

What is PerfSage Reveal?

An open-source JMeter JTL analysis tool. Upload any JTL file and get 29 expert charts, SLO verdicts, smart recommendations, and shareable HTML/PDF reports — one Docker command, no toolchain.

How is Reveal different from JMeter HTML reports?

JMeter HTML reports show what happened. Reveal explains what it means — tail latency ratios, error timelines, Apdex, and which chart to open first for your symptom.

What file formats does it accept?

Standard JMeter JTL/CSV result files from any test plan. Upload via the web UI or run the Docker container locally.

Can I define SLO thresholds?

Yes. Reveal evaluates p95/p99 latency, error rate, and throughput against your targets and surfaces pass/fail verdicts with Apdex gauges.

How do I run it?

docker pull aashu3201/reveal:latest, run the container on port 8000, upload your JTL. Full commands on this page and the launch Field Notes post.

Is it free?

Yes — open source on GitHub. For CI gates in pipelines, pair with PerfSage SLO Reporter. For prod RCA after deploy, see SignalPilot.
