Monitoring Apache DBCP connection pool
Hi,
Does anyone have a good idea on how to monitor the connection pool usage (min/max/current sizes) for Apache DBCP? Our database dashlets shows the values, so the customer wanted to have them on a chart and use them for alerting (one of their apps sometimes leaves the connections open - so when the pool is 90% full they need to restart it)?
In the past I always suggested using JMX to get those stats - but Apache DBCP does not support JMX without installing additional extensions on the Tomcat instance.
Anything else? Is there a RFE already out there for making our connection pool stats available as a standard measure that I did not find?
Thanks, Roman
