+### JMXMetric
+
+
+### Transformation
+
+Requirements:
+
+ * Must be able to transform the value
+ * Must be able to transform the name of the metric
+ * Must be configurable from the YAML configuration for a specific mbean name.
+   E.g.
+   `org.apache.ZookeeperService`ReplicatedServer_id1.QuorumSize=com.github.lookout.metricswizard.transforms..FancyIntTranform`
+ * Should be configurable from the YAML configuration for a regular expression
