Is it possible to generate charts based on jmx values ?

it would automatically solve 
https://code.google.com/p/javamelody/issues/detail?id=224&colspec=ID%20Type%20St
atus%20Priority%20Owner%20Summary
and give more possibilities.

Is it hard or easy to implement ?

Do You consider implementing such functionality ?

Currently, it's not possible.
To implement this, configuration should be simple (properties file perhaps).

Evernat, do You find it usefull?
If it's simple, will You try to add it in next release ?

useful? yes.
next release? yes, if you contribute and test the code

"you contribute" means I implement and test it and send a patch,
or you do the implementation and I test it ?

You can implement, test and send a patch.

This sounds like a great idea. 
Ideally, it should support more than "one graph per method in the JMX bean".
It should support more dynamic data.

For example, if I make a JMX bean that exposes JBoss Infinispan cache 
statistics, I want to have statistics per cache (name). This is just one 
example of "dynamic" data, that cannot be known at application startup time.

But for the JBoss Infinispan cache case, it might be that Javamelody should get 
"native" support for that, like it has for ehcache. I might look into how much 
work that would be.

I did implement the collect custom JMX bean statistics feature in a basic 
version that fits my needs. It can only add new graphs by numeric attributes in 
JMX beans. 

See:
https://github.com/evernat/javamelody/pull/2 
https://groups.google.com/forum/#!topic/javamelody/hA8Z5EfFMTY

In my opinion the requested "statistics per cache" feature is not easy to 
implement and needs more time to create a proper concept. But my implementation 
is very extensible. I think the bigest problem is how to translate the value of 
the JMX bean into multiple different counters.

The easyiest solution for the enhanced JMX feature would be to implement a 
feature for Map<String, Numeric> attributes. The implementation could be 
changed to create a graph for every entry in the map.

But does this fit all of our needs or is it just a workaround? As soon as we 
need more flexibility we have to deal with some kind of scripting language. For 
example JavaScript or Beanshell could be integrated to transform the JMX bean 
values to the appropriate information that can be visualized.
