Hi,  
I use metricbeat (jolokia) to get jmx information in Websphere.

jmx.mappings:

- mbean: 'WebSphere:type=ThreadPool,name=WebContainer,\*'  
attributes:
  - attr: maximumSize  
field: threadpool.maximumSize

The error is:  
2020-01-20T17:00:57.768+0100 INFO module/wrapper.go:252 Error fetching data for metricset jolokia.jmx: mbean properties must be in the form key=value: WebSphere:type=ThreadPool,name=  
WebContainer,\*

But If you put this url:  
jolokia-war-1.6.2/read/WebSphere:type=ThreadPool,name=WebContainer,\*  
the result is:  
{"value":{"WebSphere:cell=Cell01,mbeanIdentifier=cells/Cell01/nodes/Node01/servers/server\_01\_01/server.xml#ThreadPool\_1527689262778,name=WebContainer,node=Node01,platform=dynamicproxy,process=Fortuny\_01\_01,spec=1.0,type=ThreadPool,version=8.0.0.4":{"maximumSize":50,"name":"WebContainer","inactivityTimeout":60000,"growable":true,"minimumSize":50,"stats":{"statistics":[{"lowWaterMark":1,"highWaterMark":4,"unit":"N/A","current":2,"name":"ActiveCount","upperBound":0,"wSImpl":{"enabled":true,"highWaterMark":4,"unit":"N/A","mean":1.245895201393063,"statisticType":7,"name":"ActiveCount","integral":2.6420724E7,"lastSampleTime":1579519581782,"startTime":1579498375565,"lowWaterMark":1,"dataInfo":{"aggregatable":true,"participation":null,"unit":"N/A","level":7,"updateOnRequest":false,"dependency":null,"name":"ActiveCount","statisticSet":"basic","platform":"all","submoduleName":null,"type":5,"id":3,"description":"The number of concurrently active threads.","zosAggregatable":true,"category":"all","comment":"The number of concurrently active threads","resettable":true},"current":2,"id":3,"upperBound":0,"description":"The number of concurrently active threads.","lowerBound":0},"description":"The number of concurrently active threads.","lowerBound":0,"lastSampleTime":1579519581782,"startTime":1579498375565},{"lowWaterMark":1,"highWaterMark":50,"unit":"N/A","current":7,"name":"PoolSize","upperBound":50,"wSImpl":

Hi @vmoragar and welcome to discuss 🙂

Yeah, I am afraid that mbean definitions with wildcards in this form are not supported by Metricbeat.

Could you compare the results with this configuration?

```auto
jmx.mappings:
    mbean: 'WebSphere:type=ThreadPool,name=WebContainer,node=*'
    attributes:
        attr: maximumSize
        field: threadpool.maximumSize

```

I have created an issue in any case because it'd be nice to support wildcards on this format: [https://github.com/elastic/beats/issues/15684](https://github.com/elastic/beats/issues/15684)

Thanks for reporting!

Hi @jsoriano,  
I put this configuration  
mbean: 'WebSphere:type=ThreadPool,name=WebContainer,node=\*'

And error is:  
":"javax.management.InstanceNotFoundException : No MBean with pattern WebSphere:cell=Cell01,name=WebContainer,node=\*,type=ThreadPool

I find a work around:  
I put

- mbean: 'WebSphere:cell=Cell01,name=WebContainer,node=Node01,platform=dynamicproxy,process=server\_01\_01,spec=1.0,type=ThreadPool,version=8.0.0.4,mbeanIdentifier=\*'  
with this configuration work fine.  
thanks for all

Good to see that you found a workaround, but I wonder if with this configuration you are finding all the mbeans that you expected.

In the example request you posted on the first comment there is an mbean with a property `process=Fortuny_01_01`. I guess this is not going to be collected if the configuration contains the fixed property `process=server_01_01`.

I wonder if this configuration with two wildcards would work for this case:

```auto
mbean: 'WebSphere:cell=Cell01,name=WebContainer,node=Node01,platform=dynamicproxy,process=*,spec=1.0,type=ThreadPool,version=8.0.0.4,mbeanIdentifier=*'

```

thanks,  
I put

And work fine.
