Hi im struggling with metrics from jmx and jboss eap.

i would like to get the same metrics as we get from Prometheus:

- "jboss.as:deployment=_,subsystem=ejb3,_"
- "jboss.as:deployment=\*,subsystem=undertow"
- "jboss.as:deployment=_,subsystem=undertow,servlet=_"
- "jboss.as:deployment=_,subdeployment=_,subsystem=ejb3,\*"
- "jboss.as:deployment=_,subdeployment=_,subsystem=undertow"
- "jboss.as:deployment=_,subdeployment=_,subsystem=undertow,servlet=\*"
- "jboss.as:subsystem=datasources,data-source=\*,statistics=jdbc"
- "jboss.as:subsystem=datasources,data-source=\*,statistics=pool"
- "jboss.as:subsystem=datasources,xa-data-source=\*,statistics=jdbc"
- "jboss.as:subsystem=datasources,xa-data-source=\*,statistics=pool"
- "jboss.as:subsystem=messaging-activemq,server=_,jms-queue=_"
- "jboss.as:subsystem=messaging-activemq,server=_,jms-topic=_"
- "jboss.as:subsystem=transactions"
- "jboss.as:subsystem=undertow,server=_,http-listener=_"

i got datasources working but nothing else:  
object\_name[jboss.as:subsystem=datasources,data-source=\*,statistics=pool] attribute[AvailableCount] attribute[ActiveCount] attribute[InUseCount] attribute[TimedOut] attribute[WaitCount]

Do you have any examples for getting info about jms queue/topics and sessions???

Hi @johanostberg,

Are those all the JMX object names that you want to monitor (and that you might already capture through Prometheus) ?

From what I understand in your case

- all of the datasources (starting with `jboss.as:subsystem=datasources`) are properly captured as expected.
- all objects starting with the following prefixes are not captured
  - `jboss.as:subsystem=messaging`
  - `jboss.as:subsystem=transactions`
  - `jboss.as:subsystem=undertow`

We had a few issues with JBoss and JMX metrics in the past where JMX notifications are not consistent:

- For all of those attributes, can you tell us if are you able to read them using `jconsole` or `visualvm` tools from the JMX tree ?
- does the issue also happens when [using the runtime attach](https://www.elastic.co/guide/en/apm/agent/java/current/setup-attach-cli.html), thus without the `-javaagent` option and after JBoss server startup ?
