The MessagePerformanceUtils utility class is used to retrieve various metrics about the sizing and timing of a message sent from a client to the server and its response message, as well as pushed messages from the server to the client. Metrics are gathered when corresponding properties on the channel used are enabled: <record-message-times> denotes capturing of timing information, <record-message-sizes> denotes capturing of sizing information.

You can then use methods of this utility class to retrieve various performance information about the message that you have just received.

When these metrics are enabled an instance of this class should be created from a response, acknowledgement, or message handler using code such as below:

          var mpiutil:MessagePerformanceUtils = new MessagePerformanceUtils(event.message);

	Eigenschap		Gedefinieerd door
		clientReceiveTime : Number [alleen-lezen] Timestamp in milliseconds since epoch of when the client received response message from the server.	MessagePerformanceUtils
		constructor : Object Verwijzing naar het klasseobject of de constructorfunctie van een bepaalde objectinstantie.	Object
		messageSize : int [alleen-lezen] The size of the original client message as measured during deserialization by the server endpoint.	MessagePerformanceUtils
		networkRTT : Number [alleen-lezen] The network round trip time for a client message and the server response to it, calculated by the difference between total time and server processing time.	MessagePerformanceUtils
		originatingMessageSentTime : Number [alleen-lezen] Only populated in the case of a pushed message, timestamp in milliseconds since epoch of when the client that caused a push message sent its message.	MessagePerformanceUtils
		originatingMessageSize : Number [alleen-lezen] Only populated in the case of a pushed message, size in Bytes of the message that originally caused this pushed message.	MessagePerformanceUtils
		pushedMessageFlag : Boolean [alleen-lezen] Returns true if message was pushed to the client and is not a response to a message that originated on the client.	MessagePerformanceUtils
		pushOneWayTime : Number [alleen-lezen] Only populated in the case of a pushed message, this is the network time between the server pushing the message and the client receiving it.	MessagePerformanceUtils
		responseMessageSize : int [alleen-lezen] The size of the response message sent to the client by the server as measured during serialization at the server endpoint.	MessagePerformanceUtils
		serverAdapterExternalTime : Number [alleen-lezen] Time spent in a module invoked from the adapter associated with the destination for this message but external to it, before either the response to the message was ready or the message had been prepared to be pushed to the receiving client.	MessagePerformanceUtils
		serverAdapterTime : Number [alleen-lezen] Time spent in the adapter associated with the destination for this message before either the response to the message was ready or the message had been prepared to be pushed to the receiving client.	MessagePerformanceUtils
		serverNonAdapterTime : Number [alleen-lezen] Server processing time spent outside of the adapter associated with the destination of this message.	MessagePerformanceUtils
		serverPollDelay : Number [alleen-lezen] Time that the message waited on the server after it was ready to be pushed to the client but had not yet been polled for.	MessagePerformanceUtils
		serverPrePushTime : Number [alleen-lezen] Time between server receiving the client message and the server beginning to push messages out to other clients as a result of the original message.	MessagePerformanceUtils
		serverProcessingTime : Number [alleen-lezen] Time between server receiving the client message and either the time the server responded to the received message or had the pushed message ready to be sent to the receiving client.	MessagePerformanceUtils
		serverSendTime : Number [alleen-lezen] Timestamp in milliseconds since epoch of when the server sent a response message back to the client.	MessagePerformanceUtils
		totalPushTime : Number [alleen-lezen] Only populated in the case of a pushed message, this is the time between the push causing client sending its message and the push receving client receiving it.	MessagePerformanceUtils
		totalTime : Number [alleen-lezen] Time between this client sending a message and receiving a response for it from the server	MessagePerformanceUtils
