Subject Regarding advisory messages
Date Wed, 17 Sep 2008 20:13:18 GMT

Hi

In Active MQ 5.2, I saw advisory messages to the slow consumer.

I just subscribed to this advisory topic & printed the message below.

ActiveMQMessage {commandId = 0, responseRequired = false, messageId =
ID:DEV-1522-1221673922243-1:0:0:0:44, originalDestination = null,
originalTransactionId = null, producerId =
ID:DEV-1522-1221673922243-1:0:0:0, destination =
topic://ActiveMQ.Advisory.SlowConsumer.Topic.topictest.messages,
transactionId = null, expiration = 0, timestamp = 0, arrival = 0,
brokerInTime = 1221677995879, brokerOutTime = 1221677995879, correlationId =
null, replyTo = null, persistent = false, type = Advisory, priority = 0,
groupID = null, groupSequence = 0, targetConsumerId = null, compressed =
false, userID = null, content = null, marshalledProperties =
org.apache.activemq.util.ByteSequence@2fe8bc, dataStructure = ConsumerInfo
{commandId = 4, responseRequired = true, consumerId =
ID:DEV-1545-1221674019279-0:0:1:1, destination = topic://topictest.messages,
prefetchSize = 10000, maximumPendingMessageLimit = 0, browser = false,
dispatchAsync = true, selector = null, subscriptionName = null, noLocal =
false, exclusive = false, retroactive = false, priority = 0, brokerPath =
null, optimizedAcknowledge = false, noRangeAcks = false, additionalPredicate
= null}, redeliveryCounter = 0, size = 0, properties = null,
readOnlyProperties = true, readOnlyBody = true, droppable = false}

 I don't see certain statistics like how many messages are still pending in
the topic. Is there any additional statistics like PendingQueueSize, counter
sizes which indicates number of messages still pending that can be obtained
through this message? 

Or is this message just indicating that this particular consumer is slow for
this topic?

Thanks.
