Question on configuration variable passing

See original GitHub issue

I think its possibly a bug or my configuration mistake

I tried setting host as remote ip address

$ head -1 /app/config.yml
host: 10.42.10.34:7199

On starting it still tries to connect to localhost, here are the logs:

$ java -Dorg.slf4j.simpleLogger.defaultLogLevel=trace -jar cassandra_exporter-1.0.1-all.jar /app/config.yml

You need to enable remote access, you only have local access configured

-Dcassandra.jmx.local.port=7199
-Dcom.sun.management.jmxremote.authenticate=false

Notice the jmx.local.port

You can try out with those JMX options when starting cassandra (in cassandra-env.sh file in the config directory)

-Dcom.sun.management.jmxremote.port=7199
-Dcom.sun.management.jmxremote.rmi.port=7199 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.authenticate=false

Let me know it change anything
