Scylla JMX proxy
d67e6e60fc
In origin an undocumented feature (bug?) is that passing null as a host name for getRack and getDatacenter returns the rack or datacenter according to the loopbck address. This follow the same behaviour, so when the host is null, the function will not fail but will call the API with the local loopback address Signed-off-by: Amnon Heiman <amnon@cloudius-systems.com> Signed-off-by: Pekka Enberg <penberg@cloudius-systems.com> |

Urchin JMX Interface
This is the JMX interface for urchin.
Compile
To compile do:
mvn install
Run
The maven will create an uber-jar with all dependency under the target directory. You should run it with the remote jmx enable so the nodetool will be able to connect to it.
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7199 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -jar target/urchin-mbean-1.0.jar
Setting IP and Port
By default the the JMX would connect to a node on the localhost on port 10000.
The jmx API uses the system properties to set the IP address and Port. To change the ip address use the apiaddress property (e.g. -Dapiaddress=1.1.1.1) To change the port use the apiport (e.g. -Dapiport=10001)
