Description
This option must be included in cassandra.bat:
-javaagent:%CASSANDRA_HOME%\lib\jamm-0.2.2.jar
Otherwise you see the following warnings in cassandra log:
WARN 12:02:32,478 MemoryMeter uninitialized (jamm not specified as java agent); assuming liveRatio of 10.0. Usually this means cassandra-env.sh disabled jamm because you are using a buggy JRE; upgrade to the Sun JRE instead
