ActiveMQ Artemis Jolokia returns Status "404"

Question

I want to get the amount of messages I have in my ActiveMQ Artemis queue, but when I execute this command:

curl -v -H "Origin:http://IP:port" -u user:pass http://IP:Port/console/jolokia/read/org.apache.activemq.artemis:broker=0.0.0.0,component=addresses,address=123456,subcomponent=queues,routing-type=anycast,queue=123456/MessageCount

I get this error

"error":"javax.management.InstanceNotFoundException : org.apache.activemq.artemis:broker=0.0.0.0,component=addresses,address=123456,subcomponent=queues,routing-type=anycast,queue=123456","status":404

Do you know why? If I put this URL

http://IP:Port/console/jolokia/read/org.apache.activemq.artemis:broker=0.0.0.0,component=addresses,address=123456,subcomponent=queues,routing-type=anycast,queue=123456/MessageCount

in a browser like Chrome it works but with curl it doesn't work.

The browser may be providing additional headers that your `curl` call is not. — Robert Harvey, Oct 07 '22 at 23:05

The name of an queue's MBean follows this pattern:

org.apache.activemq.artemis:broker="brokerName",component=addresses,address="addressName",subcomponent=queues,routing-type="routingType",queue="queueName"

Note that the quotation marks are part of the MBean's name. Therefore you need to specify them in your curl command. Here's an example that works for me with the default broker:

curl -v -H "Origin: http://localhost" -u myUser:myPass http://localhost:8161/console/jolokia/read/org.apache.activemq.artemis:broker=\"0.0.0.0\",component=addresses,address=\"DLQ\",subcomponent=queues,routing-type=\"anycast\",queue=\"DLQ\"/MessageCount

Notice the quotation marks along with the proper escaping so it executes on the command-line. There is a similar (although simpler) example in the documentation.

Thanks a lot, that was the problem – Mauro Avila Oct 14 '22 at 13:35 — Mauro Avila, Oct 14 '22 at 13:35
