#cpuload "% cpu load (raw)"1 numerical MeanOverTime 100 % awk '/cpu / {printf"%d\n",$2+$3+$4}' /proc/stat
#- Collectl
cpuload "% cpu load (normalized)" 1 numerical Instantaneous 100 % COLLECTL (cputotals.user) + (cputotals.nice)
+ (cputotals.sys)
The command field must start with the string “COLLECTL” in capital letters. The line continues with
a series of collectl variables included in parenthesis and connected with arithmetical operators.
For this example, the cpuload metric reports the sum of cputotals.user, cputotals.nice, and
cputotals.sys.
For a full list of available collectl variables, run the collectl command interactively, as
follows:
# collectl –c 1 -s+C --export lexpr
The -c 1 option runs one shot only. The command output is the list of collectl variables and
the current value:
