Research direction
First, locate existing JMX beans in squbs (e.g., under org.squbs.metrics). Understand how client materialization is used and where to increment a counter. Implement a new MBean attribute exposing the count. No linked PRs or comments, so you need to design the solution. Consider adding a counter in the client materialization logic and register the MBean with the existing management context.
