The following metrics are provided through the Petals CDK, and are common to all components:
|| Metrics, as MBean attribute || Description || Detail of the value || Configurable ||
| MessageExchangeAcceptorThreadPoolMaxSize | The maximum number of threads of the message exchange acceptor thread pool | integer value, since the last startup of the component | yes, through {{acceptor-pool-size}} |
| MessageExchangeAcceptorThreadPoolCurrentSize | The current number of threads of the message exchange acceptor thread pool. *Should be always equals to* {{{*}MessageExchangeAcceptorThreadPoolMaxSize{*}{}}}*.* | instant integer value | no |
| MessageExchangeProcessorObjectPoolBorrowedObjectsCurrent | The current number of borrowed object of the message exchange processor object pool | instant integer value | no |
| MessageExchangeProcessorObjectPoolBorrowedObjectsMax | The maximum number of object of the message exchange processor object pool that was borrowed | integer value, since the last startup of the component | no |
| MessageExchangeProcessorObjectPoolIdleObjectsCurrent | The current number of idel object of the message exchange processor object pool | instant integer value | no |
| MessageExchangeProcessorObjectPoolIdleObjectsMax | The maximum number of object of the message exchange processor object pool that was idle | integer value, since the last startup of the component | no |

| MessageExchangeProcessorThreadPoolIdleThreadsCurrent | The current number of idle threads of the message exchange processor thread pool | instant integer value | no |
| MessageExchangeProcessorThreadPoolIdleThreadsMax | The maximum number of threads of the message exchange processor thread pool that was idle | integer value, since the last startup of the component | no |
| MessageExchangeProcessorThreadPoolMaxSize | The maximum size, in threads, of the message exchange processor thread pool | instant integer value | yes, through {{http-thread-pool-size-max}} |
| MessageExchangeProcessorThreadPoolMinSize | The minimum size, in threads, of the message exchange processor thread pool | instant integer value | yes, through {{http-thread-pool-size-min}} |
| MessageExchangeProcessorThreadPoolQueuedRequestsCurrent | The current number of enqueued requests waiting to be processed by the message exchange processor thread pool | instant integer value | no |
