Default Check

check_cpu
OK - CPU load is ok. |'total 5m'=13%;80;90 'total 1m'=13%;80;90 'total 5s'=13%;80;90

Checking each core by adding filter=none (disabling the filter):

check_cpu filter=none
OK - CPU load is ok. |'core1 5m'=13%;80;90 'core1 1m'=12%;80;90 'core1 5s'=9%;80;90...

Example using NRPE and Naemon

Naemon Config

define command{
    command_name         check_nrpe
    command_line         $USER1$/check_nrpe -H $HOSTADDRESS$ -n -c $ARG1$ -a $ARG2$
}

define service {
    host_name            testhost
    service_description  check_cpu
    use                  generic-service
    check_command        check_nrpe!check_cpu!'warn=load > 80' 'crit=load > 95'
}

Argument Defaults

Argument	Default Value
filter	core = ’total'
warning	load > 80
critical	load > 90
empty-state	3 (UNKNOWN)
empty-syntax	check_cpu failed to find anything with this filter.
top-syntax	%(status) - ${problem_list} on %{core_num} cores
ok-syntax	%(status) - CPU load is ok. %{total:fmt=%d}% on %{core_num} cores
detail-syntax	${time}: ${load}%

Check Specific Arguments

Argument	Description
time	The times to check, default: 5m,1m,5s
