git-hyagi/proc-parser

ABOUT

Very simple program that parses the first line from /proc/stat file. This is a workaround for situations in which we need to get a better understanding about each CPU time and we don't have the output of "top" command (like, when we have only the data from sosreport available).

RUNNING

• without parameters it will read the /proc/stat from the current system

$ go run main.go
%Cpu(s): 9.1 us, 2.6 sy, 0.1 ni, 87.3 id, 0.0 wa, 0.6 hi, 0.3 si, 0.0 st
%cpu0: 6.9 us, 1.9 sy, 0.0 ni, 90.3 id, 0.1 wa, 0.4 hi, 0.4 si, 0.0 st
%cpu1: 9.7 us, 2.7 sy, 0.1 ni, 86.4 id, 0.0 wa, 0.7 hi, 0.4 si, 0.0 st
%cpu2: 9.8 us, 2.7 sy, 0.1 ni, 86.6 id, 0.0 wa, 0.6 hi, 0.2 si, 0.0 st
%cpu3: 9.7 us, 2.8 sy, 0.1 ni, 86.5 id, 0.1 wa, 0.6 hi, 0.3 si, 0.0 st
%cpu4: 9.6 us, 2.7 sy, 0.1 ni, 86.8 id, 0.0 wa, 0.6 hi, 0.2 si, 0.0 st
%cpu5: 9.6 us, 2.7 sy, 0.1 ni, 86.8 id, 0.0 wa, 0.6 hi, 0.2 si, 0.0 st
%cpu6: 9.1 us, 2.8 sy, 0.1 ni, 86.8 id, 0.0 wa, 0.9 hi, 0.3 si, 0.0 st
%cpu7: 9.6 us, 2.8 sy, 0.1 ni, 86.6 id, 0.0 wa, 0.6 hi, 0.2 si, 0.0 st

• it is also possible to pass a stat file gathered from another system (through sosreport, for example):

$ go run main sosreport-hostabc-12345/proc/stat
