Thanks for your post. It looks like you are asking about retention in the CAS, so I am moving this to another Forum. You also have a ticket open, and we will respond to it and ensure it is in the correct location as well.
My apologies. Before I move this again, please qualify your question. ESM metric data is retained in the CAS. Are you talking about transaction metrics? Or perhaps Screenshots or Network Packet Analysis? Thanks!
If it is like Carol is guessing, you can tinker a bit with the dates and thresholds for the roll up.
This is done in the ATSCON panel, but be careful as you can cause a number of non reversable things in there.
@ Jaroslaw O. - where can we find ESM configuration details that you mentioned ? I do not see ESM under Storage Period Configuration in my CAS I can see AMD/ synthetic Backbone & lastmile/Synthetic/Rum Browser. Can you help ?
