Stats MBean for DBCP DataSources

2003-04-02 Thread Halstead, Chris 
Hello,

I was thinking of writing DBCP DataSource stats MBean for the purpose of exposing the 
metrics methods inherent in the DBCP BasicDataSource class (getNumIdle(), 
getMaxActive(), etc.).  Before I venture down that road, is this already on the 
drawing board anywhere?  Has anyone else done it already?  I sure don't want to 
reinvent the wheel, but being able to access these stats via JMX is something that we 
very much want to do.

Thanks,

-chris

I don't know of any plans, but think this would be a good idea.

You might also want to propose a patch to commons-dbcp (where
BasicDataSource comes from) to add some counters for things like how many
connections have been handed out, average time, or whatever else would be
interesting.

 Thanks,

Thanks Craig.  Adding those type of counters to BasicDataSource would be a great help. 
 I'll make a note to suggest them on the DBCP side.
