ActiveMQ JMX monitoring fails with invalid username/pass

[muelli]

Hello forum,

I have trouble monitoring an ActiveMQ 5.15.12 DB.
JMX is activated and the generic JMX template is collecting data, so this part is working.
However the Zabbix 6.0.7 template "Apache ActiveMQ via JMX" does not work, in the server log I can see errors like this:

1463827:20230201:090433.123 discovery rule "myserver:jmx.discovery[beans,"org.apache.activemq:type=Broker,brokerName= *"]" became not supported: Invalid username or password

I checked the user/pass/port data for the Host Macros, they are correct and match with the user/pass/port I have in my generic JMX template.
Any ideas? What could I check?
Thanks!

I'm using https://docs.cyclopsgroup.org/jmxterm to verify such jmx connections (from host, where java gw runs). Kind of eliminate possibility that Zabbix is to blame. If it succeeds, then also Zabbix is happy.. If not, then you should look on the other side, why it does not allow connections...

Tried this, I can log in from my Zabbix Server and use the activeMQ domain and I can get a list of the beans. So JMX is working...

Zabbix is failing at
1463827:20230201:090433.123 discovery rule "myserver:jmx.discovery[beans,"org.apache.activemq:type=Broker,brokerName= *"]" became not supported: Invalid username or password
but using this tool I can get all the brokerNames by hand:

org.apache.activemq:brokerName=myserver,connector= clientConnectors,connectorName=openwire,type=Broke r
org.apache.activemq:brokerName=myserver,connector= clientConnectors,connectorName=ssl,type=Broker

Guess something is wrong with the template?

[muelli]

Problem is solved!
The documentation for the template ist WRONG:

quote:
Set values in host macros {$ACTIVEMQ.USERNAME}, {$ACTIVEMQ.PASSWORD} and {$ACTIVEMQ.PORT}.

That is wrong and misinformation, in reality the macro for the username is called "{$ACTIVEMQ.USER}".
