Scanclass Rate vs Duration

Are there any examples for this? I mean, how to build the stats, I'd need at least the meaning of AggregateStats/RateStats items + concurrentRequests. Thanks

Can you tell me how a subscription performs the sampling part. That would help me understand the cpu load. Is it a kind of loop that performs a snapshoot of all ua tags in a tag group and compares that to a previous snapshoot to figure which tags changed and then returns the batch, that would explain the growth in cpu consumption ... or it has some mechanism to report and accumulate changes tag-wise between 2 sampling periods?

I'll have to look into this, not sure how to do this...
Start the wrapper with debug symbols then ...
What profiler do you advise?

It’s a loop in the server through all monitored items belonging to a subscription where it just asks the item for all values in its queue. Any comparison to previous value happens when the value is set on the item, not during the accumulation.
