Access to java.lang.Object attributes

[jskyworker]

I hit the same issue as #118
No errors an no data:

$>bean org.springframework.boot:name=metricsEndpoint,type=Endpoint
#bean is set to org.springframework.boot:name=metricsEndpoint,type=Endpoint
$>info
#mbean = org.springframework.boot:name=metricsEndpoint,type=Endpoint
#class name = org.springframework.boot.actuate.endpoint.jmx.DataEndpointMBean

attributes

%0 - Data (java.lang.Object, r)
%1 - EndpointClass (java.lang.String, r)
%2 - Sensitive (boolean, r)

operations

%0 - java.lang.Object getData()
%1 - java.lang.String getEndpointClass()
%2 - boolean isSensitive()
#there's no notifications
$>get Data
#mbean = org.springframework.boot:name=metricsEndpoint,type=Endpoint:

};

$>get Data.mem

How can i get metrics inside Data structure? Any help are welcome.
Thanks.

I faced the same problem. The issue is that spring boot declares the type of the Data attribute as Object. This is considered a simple type by jmxfetch and thus the entries of the map are not resolved. I solved it by creating my own JMX endpoints in spring boot similar to the existing ones but with a Map return type.
