hey @srikanthccv I have some doubts related to semantic convention of db i am posting here feel free comment

1. Is db.client.connections.usage for metric tells how many connection are currenlty in state of used or idle which can be set in upDownCounter ?

   • If it is so then i have solution related to it in pymemcache where we can intercept the pymemcache.pool.ObjectPool class which contains all the attributes required for usage metric . ref:- https://github.com/pinterest/pymemcache/blob/master/pymemcache/pool.py

2. what do you mean by db.client.connections.idle.max is it the maximum_pool value that is passed during pool intialization?

3. db.client.connections.pending_requests can you please explain this pending request scenario?
