DataStax OpsCenter Documentation

Adding custom variables to agents

OpsCenter agents do not pick up the environment variables of the currently logged-in user by default. For example, if Java is not in the machine's PATH, you may notice errors in the agent log on start-up. For example:

nohup: cannot run command 'java': No such file or directory

To correct, on the Cassandra nodes where the agents are installed, create the file /etc/default/opscenter-agent and set the environment variables for JAVA_HOME and any other custom environment variables that the agent may need. For example:

JAVA_HOME=/usr/bin/java
