Run JMXFetch as a different user (to use AttachAPI for instance)

These instructions are known to work with version 5.10.1 of the packaged linux Datadog Agent

Using the AttachAPI can require running JMXFetch as the same user as the JVM you want to monitor.

To run JMXFetch as the jmv_user user (once you've identified which user your JVM is running as), please follow these steps:

  1. Make 2 changes on the /etc/dd-agent/supervisor.conf file: supervisord should be configured to run with user=root and jmxfetch with user=jvm_user. See lines 20 and 58 of the attached file below.
  2. Add jvm_user to the dd-agent group (on Debian distros: sudo usermod -G dd-agent jvm_user, on RHEL: sudo gpasswd -a jvm_user dd-agent)
  3. Grant the dd-agent group write access to the JMXFetch log file and the agent's run directory (/opt/datadog-agent/run/): sudo chmod -R g+w /var/log/datadog/jmxfetch.log /opt/datadog-agent/run/
