Hi Philippe,

Dynatrace have no metric for the count of used connections.

dynatrace use the apache jdbc connection pool.The initial size is by default 10.
The maximum size is 50(can be changed with debugflag).
The pool closes connections that are older than 15 minutes and are not in use.

Is the count of the open connection growing over time? Or there are special times where the count is high?

Hi

Do you mean that they see DB Connections being opened from the Dynatrace Server to the Performance Warehouse Database? Or do you mean you see lots of DB Connections being opened by the application they are monitoring?
