Hi Pedro:
Well, you can certainly change the change detection rate from the monitoring profile window. You will first have to make a copy of the monitoring profile before changing the rate. Be mindful of the following note "Note: When configuring the change detection rate, consider how many devices this monitoring profile is applied to, and how frequent the metric family configuration is likely to change. Avoid setting change detection rates that are more frequent than necessary."
That is the only place I am aware of where change detection rate can be updated that would be supported
Are you looking to build some kind of custom report with device id and cmp id?
