I am doing a CE activity for some servers and data is being collected for last 3 weeks.
While observing some performance parameters I found out that for some servers the RAM utilization is almost 100% of the configured RAM.
There are 3 columns that I have seen in the "View Systems Data" page of the dashboard where it says RAM used, RAM cache and RAM pages. the RAM used and RAM Cache are almost identical (with RAM cache being lesser than RAM used).
When I extracted the progress report the RAM utilization shows 99% utilization for these servers.
Can somebody help me understand how exactly the RAM utilization is calculated and shown in the dashboard and reports?
