PINPOINT_CONTAINERfalseWhether to use docker or kubernetes. If the PINPOINT_CONTAINER environment variable is not set, the agent analyzes the'/.dockerenv' and'/proc/self/cgroup' files to determine whether to use the Docker container. If the KUBERNETES_SERVICE_HOST environment variable exists, it is determined that it is the kubernetes environment and changes it to the true value.
PINPOINT_TRACE_EXCLUSION_URL_PATTERNcomma-separated string. ex) /health_check,/admin/** or Unit tests
PINPOINT_TRACE_EXCLUSION_URL_CACHE_SIZEIf the app is designed so that the pathname of the URL is fixed, if the cache size is set, the pathname of the frequently used URL does not match with patterns. In case of using query for pathname like /user/1000, cache is unnecessarily. Unit tests

Agent ID

The agent ID is used as the identifier per the server or node. You need to set the hostname or node identifier(The maximum length is 24) on the server.

PINPOINT_AGENT_ID=${HOSTNAME} pm2 start ~/service/bin/pm2_start.json​

Sampling rate

If you use Performance tester for sampling rate, you can review while changing the sampling rate of the node agent of the Node application.

No support the JVM agent features

The Pinpoint Node agent does not support the following the JVM agent features. We plan to provide more detailed app information like the JVM agent.

  • Active Request
  • Some inspector information(Transactions Per Second, Active Request ...)
