Bryce Alcock commented on POOL-98:
----------------------------------
Getting back to Phil's Question:
Other than the current counters numActive, numIdle, and the pool properties,
what would be most useful for management?
I would like to see the following (Grouped in order of importance):
Total Objects borrowed:
Total Objects Returned:
Total Objects created:
Total Objects removed for any Reason:
Total Objects removed by eviction thread:
Total Objects removed by testOnBorrow:
Avg Borrow Time:
max Borrow Time:
Some further stats that might help but would be much more difficult to track
would be:
Avg Lend Time.
Avg Idle Time.
I have given this some thought as to "Extending GenericObjectPool" to do this,
but I don't want to because It would be nice to use the "Once Stop Shop" of
BaseConnectionPool from DBCP, which rely's on GenericObjectPool.
In the above request the first 4 groups could be done with simple counters, and
minimum synchronization, item 5 could be done with a timer and counter, and the
Avg Lend Time, and Avg Idle Time are more difficult.
> Make GenericObjectPool better extensible
> ----------------------------------------

> Key: POOL-98
> URL: https://issues.apache.org/jira/browse/POOL-98
> Project: Commons Pool
> Issue Type: Improvement
> Affects Versions: 1.3
> Reporter: Henning Schmiedehausen
> Priority: Minor
> Fix For: 2.0
>
>
> The current implementation of GenericObjectPool encapsulates the _pool
> object and there is no way to get it directly, which makes some things
> like JMX pool monitoring a bit awkward.
> Would it be possible to either make _pool protected or add a method
> protected Collection getInternalPool() {
> return _pool;
> }
> or something like that to the GenericObjectPool implementation (and
> probably others, but that is the one that bites me most... :-) )
> This would make extending the GenericObjectPool much easier.
