ps calculates CPU usage in the following manner: uptime = total time system has been running. ps_time = process start time measured in seconds from boot. pu_time = total time process has been using the CPU. ;; Seconds process has been running: seconds = uptime – ps_time ;; Usage: cpu_usage = pu_time * 1000 / seconds print: cpu_usage / 10 “.”
How to understand PS elapsed time format for long?
I notice with short-running processes, the etime (elapsed time) value takes the format minutes:seconds and from this I can easily determine how long a process has been running.
