How to check memory trend or CPU utilization trend in HANA?

I want to check memory trend or CPU utilization trend in HANA. Is there any script to check the same.

If we click on Dashboard monitoring in HANA studio & click on CPU usage, it shows current data only. I want to check memory trend for a particular period(for example 3 days). Some queries are going to be run tomorrow & we need to collect the CPU/memory stats during that time.

What is the best way to do this?Is there any script to check the same.
