If the KUBERNETES_SERVICE_HOST environment variable exists, it is determined that it is the kubernetes environment and changes it to the true value.

Agent ID

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.
