Which process was consuming most memory in the Past?
Hello
There are options / commands to check which process is consuming maximum memory
However is there any command/mechanism which will tell us which process was consuming maximum memory in specific time interval in the past?
I heard nmon report can help in this regard.
is there any other option available?
Thanks and Regards
