Interpreting k6 Metrics
Understand k6's detailed metrics, custom tags, and how to visualize them for insights.
What are k6 Metrics?
When you run a k6 performance test, it generates various metrics. These are numerical values that describe your system's behavior under load.
Understanding these metrics is crucial for identifying performance bottlenecks, verifying service level agreements (SLAs), and ensuring your application can handle expected traffic.
Key Metric: Request Duration
One of the most important built-in k6 metrics is http_req_duration. This measures the total time it takes for an HTTP request to complete.
- It starts when the request is sent.
- It ends when the full response is received.
- It directly reflects the response time users experience.
