Configuring the DataStax Agent JVM

The DataStax Agent JVM is designed to have a minimal footprint on your nodes and simply work without extra configuration for most environments.

JVM properties for the agent are configured in The default location of this DataStax agent environment shell script depends on the type of installation:

  • Package installations: /etc/datastax-agent/

  • Tarball installations: install_location/agent/conf/

Agent Heap Size

For most environments, the DataStax agent will require 1GB of heap. If an agent is experiencing OutOfMemory issues, try changing the -Xmx property in to 2048M (-Xmx2048M). If issues still persist, please contact DataStax Support so DataStax can determine whether your environment requires even more heap or if there is an issue in the agent.
