UNIX/LINUX SNMP CPU IDLE with STATs

Description

This plugin monitors CPU Idle of UNIX/LINUX OS and gets a lot of additional Info from SNMPD. Plugin checks are made via SNMP v2c/3 and returns CPU Idle percent in Output and Perfdata and other stats in Performance data. REQUIRE include .1.3.6.1.4.1.2021 in snmpd.conf STATS, that are getting by this plugin: user_cpu_time_percent = .1.3.6.1.4.1.2021.11.9.0 system_cpu_time_percent = .1.3.6.1.4.1.2021.11.10.0 idle_cpu_time_percent = .1.3.6.1.4.1.2021.11.11.0 raw_user_cpu_time = .1.3.6.1.4.1.2021.11.50.0 raw_nice_cpu_time = .1.3.6.1.4.1.2021.11.51.0 raw_system_cpu_time = .1.3.6.1.4.1.2021.11.52.0 raw_idle_cpu_time = .1.3.6.1.4.1.2021.11.53.0 raw_wait_cpu_time = .1.3.6.1.4.1.2021.11.54.0 raw_kernel_cpu_time = .1.3.6.1.4.1.2021.11.55.0 raw_interrupt_cpu_time_oid = .1.3.6.1.4.1.2021.11.56.0 Plugin Requires this perl modules: Net::SNMP, Getopt::Long Example of plugin usage and results: $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 40 -c 30 SNMP OK - OS: CPU_Idle 91 | 'OS: CPU_Idle'=91;40;30;0;0; user_cpu_time_percent=7 system_cpu_time_percent=1 raw_user_cpu_time=2430124993 raw_nice_cpu_time=1254974 raw_system_cpu_time=431663749 raw_idle_cpu_time=382079558 raw_wait_cpu_time=7422831 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95 -c 80 SNMP WARNING - OS: CPU_Idle 92 | 'OS: CPU_Idle'=92;95;80;0;0; user_cpu_time_percent=6 system_cpu_time_percent=1 raw_user_cpu_time=2430127289 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664080 raw_idle_cpu_time=382100867 raw_wait_cpu_time=7422838 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95 -c 92 SNMP CRITICAL - OS: CPU_Idle 92 | 'OS: CPU_Idle'=92;95;92;0;0; user_cpu_time_percent=6 system_cpu_time_percent=0 raw_user_cpu_time=2430127382 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664097 raw_idle_cpu_time=382112743 raw_wait_cpu_time=7422840 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95:94 -c 92:91 SNMP CRITICAL - OS: CPU_Idle 91 | 'OS: CPU_Idle'=91;95:94;92:91;0;0; user_cpu_time_percent=7 system_cpu_time_percent=1 raw_user_cpu_time=2430130433 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664607 raw_idle_cpu_time=382145091 raw_wait_cpu_time=7422847 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95:94 -c 92:90 SNMP CRITICAL - OS: CPU_Idle 91 | 'OS: CPU_Idle'=91;95:94;92:90;0;0; user_cpu_time_percent=6 system_cpu_time_percent=1 raw_user_cpu_time=2430130599 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664638 raw_idle_cpu_time=382156876 raw_wait_cpu_time=7422848 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95:94 -c 90:80 SNMP CRITICAL - OS: CPU_Idle 90 | 'OS: CPU_Idle'=90;95:94;90:80;0;0; user_cpu_time_percent=8 system_cpu_time_percent=1 raw_user_cpu_time=2430132586 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664860 raw_idle_cpu_time=382166621 raw_wait_cpu_time=7422851 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 $ ./check_snmp_cpu_stats.pl -H 127.0.0.1 -C public -w 95:94 -c 85:80 SNMP OK - OS: CPU_Idle 91 | 'OS: CPU_Idle'=91;95:94;85:80;0;0; user_cpu_time_percent=7 system_cpu_time_percent=1 raw_user_cpu_time=2430133045 raw_nice_cpu_time=1254974 raw_system_cpu_time=431664893 raw_idle_cpu_time=382178111 raw_wait_cpu_time=7422852 raw_kernel_cpu_time=0 raw_interrupt_cpu_time=18599 Nagios commands.cfg config can be like this: ## SNMP CPU Idle with CPU Stats in Perfdata define command{ command_name check_snmp_cpu_idle_with_stats command_line $USER1$/contrib/check_snmp_cpu_stats.pl -H $HOSTADDRESS$ -C $ARG1$ -p $ARG2$ -w $ARG3$ -c $ARG4$ } Service config for Nagios can be like this: define service{ use generic-service service_description OS: CPU_Idle host_name server1.server2 contact_groups server-admins active_checks_enabled 1 passive_checks_enabled 1 max_check_attempts 1 check_interval 3 retry_interval 5 check_period 24x7 notification_options w,c,r notification_interval 120 check_command check_snmp_cpu_idle_with_stats!public!161!50!20! } ############ Changelog ############### 0.2 - SNMPERROR exception 0.1 - initial release.
