Я не могу заставить OpenNMS отправлять сообщения в конечную точку AMQP. У меня никогда не было этой работы, и это первый раз, когда я использовал OpenNMS и AMQP, так что это могло бы свести мою неопытность.OpenNMS v18 AMQP Сообщение Отправка сообщения
Я настроил RabbitMQ 3.5.7 и протестировал его согласно этому question. Он отлично работает при использовании внешнего клиента QPID 0.32, а также отлично работает при использовании python или perl. Определение прекрасных работ заключается в том, что связь установлена, и полезная нагрузка сообщения передается в обмен, а затем передается в бэкэнд-очередь. Сообщение можно просмотреть в графическом интерфейсе администратора RabbitMQ.
В OpenNMS я следил за инструкциями here Начал с EventForwarder, а затем попробовал AlarmNorthbounder и получил исключение NullPointerException.
настроить Karaf следующим образом настройка свойств с помощью этих операторов: -
opennms> config:edit org.opennms.features.amqp.alarmnorthbounder
opennms> propset connectionUrl amqp://simon:[email protected]/test?brokerlist=\'localhost:5672\'
opennms> propset destination "amqp:onms3/Simon;{'create':'always','node':{'type':'topic'} }"
opennms> propset processorName default-alarm-northbounder-processor

Мое предположение состояло в том, что это была проблема подключения к серверу AMQP некоторого описания. Столкнувшись с рядом проблем во время устранения неполадок, если я столкнулся с проблемой из внешней банки, из журналов было ясно, в чем проблема. Это проблема с OpenNMS? У кого-нибудь это работает успешно? Любые идеи?
Приветствия

Извините, как я могу просмотреть журнал OpenNMS org.opennms.features.amqp.alarmnorthbounder? – sintetico82
