How can I retrieve the list of configured acceptors in ActiveMQ Artemis via Jolokia/JMX (and curl)? I need to reload the acceptors after a TLS certificate update but looks like passing the acceptor name is mandatory. Unfortunately, I cannot just pass a static name because we use different acceptors, all using TLS – and don’t want to change the reloading code just because the acceptor config changed.
curl -s -f -u username:password -H 'Origin: localhost' 'http://127.0.0.1:8161/console/jolokia/read/org.apache.activemq.artemis:broker="borker-primary-0"'
shows the connectors, but not the acceptors.
This question is related to a change introduced in v2.18.0, see question on TLS certificate reload.
There is a getConnectors method on the main ActiveMQServerControl MBean which is why Jolokia's read command returns those values. However, there is no corresponding getAcceptors method, but you can use Jolokia's list command to effectively get the same information. Use something like this:
curl -s -f -u username:password -H 'Origin: localhost' 'http://127.0.0.1:8161/console/jolokia/list/org.apache.activemq.artemis:broker="borker-primary-0"'
Then look through the results for component=acceptors and you'll be able to find all the acceptors with their respective names.
This is a bit of a hack but a necessary one at this point given the lack of a management method to get the acceptors. I've opened ARTEMIS-3601 and sent a PR to deal with this use-case so in future versions this won't be necessary. You'll just be able to invoke getAcceptors or inspect them from the output of Jolokia's read command.
