hotspot/svc-agent is for issues concerning the serviceability agent (code in src/jdk.hotspot.agent/* and vmStructs.cpp). JMX issues goes into core-svc/ Both of these components are considered part of the M&M area. (They also have core-svc/

As for the serviceability area there are components like: hotspot/jvmti, hotspot/svc, core-svc/debugger, core-svc/tools, core-svc/java.lang.instrument, and tools/hprof. Some of these have fairly descriptive names, the rest I leave for the serviceability folks to sort out :-)
