>                 Key: POOL-410
>                 URL: https://issues.apache.org/jira/browse/POOL-410
>             Project: Commons Pool
>          Issue Type: Improvement
>            Reporter: Thomas Freller
>            Priority: Major
>             Fix For: 2.13
>
>
> For tuning the Database the max concurrent used connections wold be relay 
> great.
>  
> So I could monitor the max concurrent connections of my pool and could see if 
> I have to size up/down the max database connections (that can me memory 
> intensive) or if I could downsize the Pool and also the Database i could save 
> Memory and costs.  At the Moment the only Indicator is 
> maxBorrowWaitDuration=PT3.016S,
>  
> But this can only tell me hat at the Moment the pool reached its max (because 
> I set maxTotal to 1) my normal Case is to have up to 20 Pools of different 
> Applications that connect to one instance of MariaDB and the output of 
> maxBorrowWaitDuration is 0. So I only know I would be able to downsize the 
> pool but I have no hint how to size the pool best.
> This Statistical Data should be also printed in the toString() Method.
