Question

我目前正在尝试从ActiveMQ中检索统计信息。我使用ActiveMQ 5.11.1并将statisticsBrokerPlugin添加到配置文件中。正如在此处指定的那样：http://activemq.apache.org/statisticsplugin.html，我向ActiveMQ.Statistics.Subscription发送空消息以检索所有队列和主题订阅。

运行时，大多数情况下发送邮件时会出错。类似的东西：

Caused by: javax.management.InstanceNotFoundException: org.apache.activemq:type=Broker,brokerName=localhost,destinationType=Queue,destinationName=prod.import.csv,endpoint=Consumer,clientId=ID_tadpole-import-5-38631-1438235942638-2_17,consumerId=ID_tadpole-import-5-38631-1438235942638-3_17_1_14503

以下是代码的有用部分：

val factory = new ActiveMQConnectionFactory(activeMQConn)
factory.setWatchTopicAdvisories(false)
val connection = factory.createConnection()
connection.start()

val session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE)
val replyTo = session.createTemporaryQueue()
val consumer = session.createConsumer(replyTo)
val queueName = "ActiveMQ.Statistics.Subscription"
val testQueue = session.createQueue(queueName)
val producer = session.createProducer(testQueue)
val msg = session.createMessage()
msg.setJMSReplyTo(replyTo)
producer.send(msg) // this will trigger the error

知道如何解决这个问题吗？

由于

PS：

我们的系统正在处理数百个列表和数千条消息
它不会一直失败，可能是90％。
目的地名称＆amp; consumerId似乎经常变化。
我没有在activemq的日志中看到任何错误。

使用statistics插件时，ActiveMq引发了javax.management.InstanceNotFoundException
