Apache Cassandra Startup Settings

The Java Agent bootstraps using the javaagent command line option. Add this option to the cassandra (Linux) or cassandra.bat (Windows) file.

Instrument Cassandra in a Windows Environment

1. Open the apache-cassandra-x.x.x\bin\cassandra.bat file.

2. Add the Java Agent javaagent path to the JAVA_OPTS variable. Make sure to include the drive in the full path to the Java Agent directory.

   -javaagent:<agent_home>\javaagent.jar
   

   CODE

   For example:

   set JAVA_OPTS=-ea
       -javaagent:C:\appdynamics\agent\javaagent.jar
       -javaagent:"%CASSANDRA_HOME%\lib\jamm-0.2.5.jar
       . . .
   

   CODE
3. Restart the Cassandra server for the changes to take effect.

Instrument Cassandra in a Linux Environment

1. Open the apache-cassandra-x.x.x/bin/cassandra.in.sh file.

2. Add the javaagent argument at the top of the file:

   JVM_OPTS=-javaagent:<agent_home>/javaagent.jar
   

   CODE

   For example:

   JVM_OPTS=-javaagent:/home/software/appdynamics/agent/javaagent.jar

   CODE
3. Restart the Cassandra server for the changes to take effect.
