> Removal of the JMX interface removes the ability of the user to conveniently monitor key JVM statistics such as heap utilisation, garbage collection statistics.
> The Broker model should be enhanced to include such information as below:
> || Name || Type || Description ||
> |lastOpenedTime|Derived Attribute|Last opening time for CO |
> |numberOfLiveThreads|Statistic|Number of live threads|
> |maximumHeapMemorySize|Derived Attribute|Maximum heap size|
> |usedHeapMemorySize|Statistic|Size of used memory|
> |maximumDirectMemorySize|Derived Attribute|Maximum direct memory size which can be consumed by broker|
> |usedDirectMemorySize|Statistic|Size of used direct memory|
> |totalDirectMemoryCapacity|Statistic|Total capacity of direct memory allocated for the Broker process|
> |jvmMemoryUsed<pool name>|Statistic|Usage of memory by particular memory pool|
> |jvmMemoryMaximum<pool name>|Derived Attribute|Maximum size of memory pool|
> |jvmGCCollectionTime<GC name>|Statistic |Aggregated time taken (ms) by GC to perform collections|
> |jvmGCCollectionCount<GC name>|Statistic|Aggregated number of GC collections|
> |numberOfObjectPendingFinalization|Statistic|Number of objects pending finalization|
> |jvmArguments|Derived Attribute|JVM arguments specified on startup|
> |performCG|Operation|Initiates garbage collection|
> |String getStackTraces(boolean appendToLog) | Operation| Collects thread stack traces for all threads and dump them into logs if requested|
> |String findStackTraces(String threadNameMatchExpression) |Operation |Collects thread stack traces for threads with name matching fiven RegExp|
> |setJVMOptions(Map<String,String> options)|Operation|Sets given key-value pairs as JVM options|
> |dumpHeap(String, boolean)|Operation|Collects heap dump|
