Yes, you can check this from the MySQL's inbuilt command called "mysqladmin processlist", which displays the exact amount of queries being fired/executed at that moment. You can check the exact user which is causing overloading issues (using most resources (CPU/MEM)) for MySQL from the WHM interface from Main >> System Health >> Show Current CPU Usage.
