Testing using K6 Grafana

Typical Setup

1. k6 — Runs the test scripts and generates metrics.

2. InfluxDB — Collects and stores time-series data generated by k6.

3. Grafana — Visualizes the metrics in customizable dashboards.

🔧 How It Works

• k6 sends real-time metrics to InfluxDB.

• Grafana queries InfluxDB and displays test data like:

  • Request rates

  • Response times

  • Error rates

  • System throughput

  • Thresholds and SLA compliance

🧪 Example Use Case

You’re testing a login API under load:

• Write a k6 script to simulate 100 virtual users logging in.

• Run the test and send metrics to InfluxDB.

• View charts in Grafana showing average response time, failures, and system bottlenecks in real-time.

Benefits

• Developer-friendly (JS scripting).

• Scalable and CI-friendly.

• Real-time visibility with Grafana.

• Helps identify performance regressions early.
