mbeans as Arrays

[cyrille-leclerc]

Hi Geoff,

Could we:

• introduce a index attribute in the definition of a query to specify which element of an iterable value (collection or array) should be picked

  <query objectName="MyDomain:type=MyMBean,name=*" attribute="zeArrayAttribute" index="20"  
             resultAlias="zeArrayAttributeValueIWant"/>
  

• if query.index attribute is not defined and the value is an iterable, then we output 1 entry per element of the returned iterable value suffixing the resultAlias by _${index} (e.g. resultAlias="zeAttribute" would return zeAttribute_0=123, zeAttribute_1=456, ...)

That sounds perfect to me.

Hi Geoff,

I have implemented this feature in 1.0.3 (should be available in Maven Central in 2 or 3 hours).

I chose a slightly different name for the config param, it's position(instead of index).

 <query objectName="MyApp:type=MyMBean" attribute="MyMultiValuedAttribute" position="2"
    resultAlias="myMBean.myMultiValuedAttributeValue"/>

All the details at https://github.com/jmxtrans/jmxtrans-agent#multi-valued-attribute-iterable-or-array

Can you please check and tell us if it's ok?

Verified. Works perfectly.
