atop -r atop-raw-file -b 12:00 -e 13:00

atopsar
-O Report about top-3 processes consuming most processor capacity.
-G Report about top-3 processes consuming most resident memory.
-D Report about top-3 processes issueing most disk transfers.
-N Report about top-3 processes issueing most IPv4/IPv6 socket
