Debugging max connection pool reached

Question

Our app is getting a max connection pool reached on pick times when we run large db actions.

I want to debug this situation, My idea is to check how many connections are open every couple of minuets and if i reach a trash-hold to print all the opened queries in the db.

Is that a good approach? Also, does anyone knows how can i check the how many open connection are there, googling didnt help so far.

I am using MySQL.

TY, Please tell me if any information is missing

Answer 1

Please verify: 1. Use connection pooling - enabled by default (it may turn off) 2. Do not create a globally accessible instance of MySqlConnection and then manually open and close it
