Hi David,
Thanks for your reply , It seems top command also uses
/proc/stat to do the magic .Reading a similar issue for top vs another monitor
tool on
https://medium.com/@yogita088/how-to-calculate-cpu-usage-proc-stat-vs-top-e74f99f02d08
, What is the duration for which getProcessCPUload reports CPU utilisation ,
is it from system start time or 1 sec or x seconds ? It is configurable in top
command as -d parameter. This might help to discover difference btw top vs
getprocesscpuload
regards
Nikhil

I've no idea how top calculates what it does. The VM reads the first line of
/proc/stat to get the various tick counters.
HTH.
