Configuring the DataStax agent JVM

Configure the JVM parameters for the DataStax agent JVM.

datastax-agent-env.sh

The default location of the DataStax agent environment shell script datastax-agent-env.sh depends on the type of installation:
  • Package installations: /etc/datastax-agent/datastax-agent-env.sh
  • Tarball installations: install_location/agent/conf/datastax-agent-env.sh

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 datastax-agent-env.sh.

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 datastax-agent-env.sh 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.
