perf-reporting

perf-reporting generates professional performance reports from raw JMeter, k6, and Gatling output — Apdex scores, SLA checks, percentile charts, and exportable HTML/PDF reports.

Installation

Desktop App (Windows / macOS / Linux)

Download from martkos-it.co.uk/store/perf-reporting-dashboard. Requires a free license key (emailed on registration) entered on first launch.

CLI

npm install -g @martkos-it/perf-reporting
perf-reporting --version

Web Dashboard

The web version runs at martkos-it.co.uk/tools/perf-reporting — upload a results file and get an interactive report in your browser.

Generating a Report

# From k6 JSON output
perf-reporting generate \
  --file results.json \
  --tool k6 \
  --output report.html

# From JMeter JTL
perf-reporting generate \
  --file results.jtl \
  --tool jmeter \
  --output report.html

# From Gatling simulation.log
perf-reporting generate \
  --file simulation.log \
  --tool gatling \
  --output report.html

SLA Thresholds

Define SLA thresholds inline or via perf-ecosystem.yml:

perf-reporting generate \
  --file results.json \
  --tool k6 \
  --sla-p95=1500 \
  --sla-p99=3000 \
  --sla-error-rate=1.0 \
  --sla-apdex=0.85 \
  --output report.html

The report shows pass/fail status per threshold with a summary section at the top.

perf-ecosystem.yml

When perf-ecosystem.yml is present, thresholds are picked up automatically:

thresholds:
  response_time:
    p95_max_ms: 1500
    p99_max_ms: 3000
  error_rate:
    max_percent: 1.0
  apdex:
    min_score: 0.85

Uploading to perf-results-db

perf-reporting generate \
  --file results.json \
  --tool k6 \
  --push-to-results-db \
  --results-db-url http://localhost:4000 \
  --results-db-api-key prdb_your_key \
  --project-id your-project-uuid \
  --output report.html

Report Contents

• Summary: Apdex score, pass/fail SLA status, test duration, total requests
• Response time distribution: p50, p75, p90, p95, p99, min, max
• Throughput: requests/second over time
• Error analysis: error rate, error types, failed samplers
• Per-endpoint breakdown: response times and error rates per URL/sampler
• Charts: timeline charts for response time and throughput

PDF Export

perf-reporting generate --file results.json --tool k6 --format pdf --output report.pdf

Requires Chromium (bundled with the Electron app; on CLI, uses puppeteer headless).

Apdex Score

Apdex is calculated using configurable satisfied (T) and frustrated (4T) thresholds:

perf-reporting generate --file results.json --tool k6 --apdex-t=500
# Satisfied: ≤500ms, Tolerating: 500ms–2000ms, Frustrated: >2000ms

Default T = 500ms. Apdex formula: (satisfied + tolerating/2) / total_requests
