我无法让OpenNMS将消息发送到AMQP端点。 我从来没有这样的工作，这是我第一次使用OpenNMS和AMQP，所以这可能是我缺乏经验。
我已经配置了RabbitMQ 3.5.7并按照question进行了测试。 它在使用外部QPID 0.32客户端时工作正常，并且在使用python或perl时也能正常工作。 工作的定义很好，即建立通信并将消息有效负载传输到交换机中，然后传送到后端队列。 然后可以在RabbitMQ Admin GUI中查看消息。
在OpenNMS中，我一直关注指示here 从EventForwarder开始，然后尝试使用AlarmNorthbounder，产生NullPointerException。
我按照以下方式设置了Karaf：使用这些语句设置属性： -
opennms> config:edit org.opennms.features.amqp.alarmnorthbounder
opennms> propset connectionUrl amqp://simon:simon@/test?brokerlist=\'localhost:5672\'
opennms> propset destination "amqp:onms3/Simon;{'create':'always','node':{'type':'topic'} }"
opennms> propset processorName default-alarm-northbounder-processor
opennms> config:update
opennms> config:list '(service.pid=org.opennms.features.amqp.alarmnorthbounder)'

我的假设是这是某些描述的AMQP服务器的连接问题。如果我从外部jar面临问题，在解决此问题时遇到了一些问题，从日志中可以清楚地看出问题是什么。 这是OpenNMS的问题吗？ 有没有人有这个成功的工作？ 有什么想法吗？
干杯

答案 0 :(得分：0)
根据OpenNMS列表的指导，我决定安装QPID Broker v6.0.3代替RabbitMQ，现在消息没有问题。
