HOWTO - Total memory and CPU usage ... without top?
Hi all,
Is it possible to get total memory usage and free memory usage without top? By Googling I found for total memory usage, use vmstat, for CPU, use mpstat, for disk I/O use iostat, is this correct? Will using sar gives the same result as ALL of these three (3) commands?
What about if I want to get CPU and memory usage information for a particular process, use ps?
Any advise will be much appreciated. Thanks in advance.
