Some operations are not changing frequently and are called multiple time during a nodetool execution. This patch adds the ability to cache results for a define period of time (typically it will be for a few seconds) so that during the same nodetool command call, the results will be retrieved from the cache. It is currently only implemented for string values, other commands will be added when needed. Signed-off-by: Amnon Heiman <amnon@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)
