Add custom counters #251

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It would be really useful to be able to have custom counters within an app that 
I can inform Java Melody about and Java Melody keeps the stats on and graphs 
and reports.

Sorry I mean this to be a feature request, not a defect.

This would be really useful in our production environment, we already use 
JavaMelody and this would allow us to periodically log some information (like 
number of objects in a specific queue etc.) that we could then analyze using 
the normal JavaMelody graphs etc.

Java Simon has this feature 
http://javasimon.googlecode.com/svn/javadoc/api-3.0/org/javasimon/Counter.html, 
i think we need only some API to set value

If your goal is to display stats in a table about durations of some operations, 
then look at Monitoring services/façades with EJB, Spring or Guice or withtout 
in the user guide:
https://code.google.com/p/javamelody/wiki/UserGuideAdvanced#Business_facades_%28
without_EJB3_and_without_Spring_and_without_Gu
https://code.google.com/p/javamelody/wiki/UserGuide#8._Business_facades_%28ejb-j
ar.xml_file_if_EJB3%29

Otherwise, if your goal is to display new graphs of some other values, then I 
think that the right enhancement for this is a said in issue 384. That is a 
parameter which lists names of JMX/MBean, and either these MBeans already 
exists from some tool (hibernate, connection pool, etc) or you create these 
MBeans. (javamelody may also provide an api to help creating MBeans). With this 
parameter javamelody will be able to read values periodically from MBeans and 
display the values in new graphs.

Yes, solving issue 384 would solve this issue as well, I think.
I will add a few comments to 384 about that would be nice about that feature.

I did implement the collect custom JMX bean statistics feature in a basic 
version that fits my needs.
