Metrics Wizard is a Java agent for aggregating and reporting on metrics from any JVM process.
The agent will scan and automatically register metrics based on long/integer/float values in the JMX tree of the monitored JVM process.
We highly recommend using dropwizard-metrics for the reporting of metrics in various forms from within an existing application.
Metrics Wizard is built to scan the tree of attributes in JMX and monitor the metrics presented. For the most part plugging Metrics Wizard into an existing process, like Cassandra, should "just work."
