scylla-jmx [$PARAM_HELP] [$PARAM_API_PORT port] [$PARAM_ADDR address] [$PARAM_JMX_PORT port] [$PARAM_FILE file]

This script is used to run the jmx proxy

By default it would connect to the local API ($API_ADDR) and will listen on the JMX port ($JMX_PORT)

This script receives the following command line arguments:

    $PARAM_HELP - print this help screen and exit
    $PARAM_JMX_PORT <port> - The jmx port to open
    $PARAM_API_PORT <port> - The API port to connect to
    $PARAM_ADDR <address> - The API address to connect to
    $PARAM_FILE <file> - A configuration file to use
    $PARAM_LOCATION <location> - The location of the jmx proxy jar file
    $ALLOW_REMOTE - When set allow remote jmx connectivity
HLPEND
}
