通过 TCP 连接使用 Jolokia 检查 AMQ Artemis 代理是否健康

Question

We have an Openshift project ( project1 ) in which we setup an AMQ Artemis broker using the image : amq- amq-broker-7-tech-preview/amq-broker-71-openshif . Being the basic image we don't have any configuration such as SSL or TLS. In order to do the setup we used as example : https://github.com/jboss-container-images/jboss-amq-7-broker-openshift-image/blob/amq71-dev/templates/amq-broker-71-basic.yaml

After the deployment of the image on Openshift we have the following:

• broker-amq-amqp (5672/TCP 5672) No route
• broker-amq-jolokia (8161/TCP 8161) No Route
• broker-amq-mqtt ( 1883/TCP 1883 ) No route
• broker-amq-stomp ( 61613/TCP 61613 ) No route
• broker-amq-tcp ( 61616/TCP 61616 ) No route

My question is : how we can check if the broker is healthy using the TCP connection to broker-amq-jolokia ? So far we connected using TCP Sockets in Java to broker-amq-jolokia but we don't know what message in order for Jolokia to respond with the health status of the broker

Answer 1

ActiveMQ Artemis has a lot of beans exposed by jolokia and they can be used to perform the required health checks.

For a standalone broker could be useful to check:

• the broker is started console/jolokia/read/org.apache.activemq.artemis:broker=\\"$BROKER_NAME\\"/Started
• the disk store usage console/jolokia/read/org.apache.activemq.artemis:broker=\\"$BROKER_NAME\\"/DiskStoreUsage
• the address memory usage console/jolokia/read/org.apache.activemq.artemis:broker=\\"$BROKER_NAME\\"/AddressMemoryUsagePercentage

For a cluster of brokers could be useful to check the topology: console/jolokia/exec/org.apache.activemq.artemis:broker=\\"$BROKER_NAME\\"/listNetworkTopology

All this checks and others can be executed using the tool artemis check , ie:

./bin/artemis check queue --name TEST --produce 1000 --browse 1000 --consume 1000 --url tcp://$BROKER_IP:61616
