Cloud tests can export their metrics in near real-time to application performance monitoring (APM) platforms. By combining k6 Cloud with an APM, you can correlate and query testing metrics with other system metrics.
⭐️ Cloud APM integrations are available on Pro and Enterprise plans, as well as the annual Team plan and Trial.
Each test has to set up its APM settings to export the metrics of its run. Some ways you can customize export to your use case:
- Configure a test to export to multiple different APM providers.
- Configure the APM settings using the k6 Cloud app and test builder or scripting the k6 test.
For details, refer to the instructions on integrating different APM platforms:
By default, the APM integrations export only the default APM metrics, a subset of all k6 metrics.
The includeDefaultMetrics option in the k6 script controls whether to export the default APM metrics or not. The default APM metrics are:
|vus||Gauge||Current number of active virtual users|
|iterations||Counter||The aggregate number of times the VUs in the test have executed the JS script.|
|data_received||Counter||The amount of received data.|
|data_sent||Counter||The amount of data sent.|
|http_reqs||Counter||How many HTTP requests has k6 generated, in total.|
|http_req_duration||Trend||HTTP request execution time.|
If you're unfamiliar with the different types of k6 metrics, refer to the Metrics reference.
By default, k6 limits export to only these metrics to avoid unexpected costs with your APM provider. APM providers charge based on the number of stored metrics, and a load test can generate a massive volume of metrics.
To select the metrics to export, use the metrics option. In the k6 script, you can set both options - includeDefaultMetrics and metrics - as follows:
