Unisphere seemingly flooded with too many users/REST API calls

Hi All.  It seems our UniSphere for PowerMAX 11.2.X.X is being flooded with too many REST API calls. We know one person who does that at times is Dell EMC (ViPR) SRM, and another Monitoring Tools also does that at times during the day. However, we want to know the total usage. And, need a way to find how many such calls are being made from all over the map. Is there any way to determine that. Any command or some tool to do that.  We do know that - A maximum of 5 REST API clients can connect to the Unisphere server concurrently. A maximum of 50 GET calls can be made to the Unisphere server per second. But we want to know the total usage being carried out here. As,  we keep getting thrown out of the UniSphere GUI the moment we start working on it. Weird.  Not sure if we are starving it and it can no longer serve us.   Please advise.   Best
