Hyper-V CPU counters using check_nt

I was inspired from this article: http://windowsitpro.com/hyper-v/hyper-v-performance-counters Read it to understand what each counter represent and how can it help you. For a Nagios deployment use the following commands (add them in commands.cfg): ############################################################## define command{ command_name hv-logical-processor command_line $USER1$/check_nt -H $HOSTADDRESS$ -s $USER4$ -p 12489 -v COUNTER -l "Hyper-V Hypervisor Logical Processor(_Total)% Total Run Time","overall the Logical Processors" -w 80 -c 90 } define command{ command_name hv-root-virtual-processor command_line $USER1$/check_nt -H $HOSTADDRESS$ -s $USER4$ -p 12489 -v COUNTER -l "Hyper-V Hypervisor Root Virtual Processor(_Total)% Total Run Time","overall the Root Virtual Processor" -w 80 -c 90 } define command{ command_name hv-virtual-processors command_line $USER1$/check_nt -H $HOSTADDRESS$ -s $USER4$ -p 12489 -v COUNTER -l "Hyper-V Hypervisor Virtual Processor(_Total)% Total Run Time","overall the Virtual Processors" -w 80 -c 90 } define command{ command_name hv-virtual-processor command_line $USER1$/check_nt -H $HOSTADDRESS$ -s $USER4$ -p 12489 -v COUNTER -l "Hyper-V Hypervisor Virtual Processor($ARG1$)% Total Run Time","Virtual Processor $ARG1$" -w 80 -c 90 } ############################################################## ... create Host Groups and Service Groups by adding into windows.cfg the following (replace HvServer1,HvServer2 with your servernames): ############################################################## define hostgroup{ hostgroup_name hyper-v-servers alias Hyper-V Servers members HvServer1,HvServer2 } define servicegroup{ servicegroup_name hyper-v alias Hyper-V performance } ############################################################## ... define services for monitoring the _total counters: ############################################################## define service{ use generic-service hostgroup_name hyper-v-servers service_description Hypervisor Logical Processor _total check_command hv-logical-processor servicegroups hyper-v } define service{ use generic-service hostgroup_name hyper-v-servers service_description Hypervisor Root Virtual Processor _total check_command hv-root-virtual-processor servicegroups hyper-v } define service{ use generic-service hostgroup_name hyper-v-servers service_description Hypervisor Virtual Processors _total check_command hv-virtual-processors servicegroups hyper-v } ############################################################## ... define services to monitor the Virtual Processor counters on individual VMs (in this example we have a VM named Nagios1 hosted on HvServer1 with 2 virtual processors, a VM named Server1 hosted on HvServer1 with 2 virtual processors and a VM named Server2 hosted on HvServer2 with 4 virtual processors): ############################################################## define service{ use generic-service service_description Hypervisor Virtual Processor Nagios1 VP0 check_command hv-virtual-processor!Nagios1:Hv VP 0 host_name HvServer1 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Nagios1 VP1 check_command hv-virtual-processor!Nagios1:Hv VP 1 host_name HvServer1 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server1 VP0 check_command hv-virtual-processor!Server1:Hv VP 0 host_name HvServer1 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server1 VP1 check_command hv-virtual-processor!Server1:Hv VP 1 host_name HvServer1 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server2 VP0 check_command hv-virtual-processor!Server2:Hv VP 0 host_name HvServer2 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server2 VP1 check_command hv-virtual-processor!Server2:Hv VP 1 host_name HvServer2 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server2 VP2 check_command hv-virtual-processor!Server2:Hv VP 2 host_name HvServer2 servicegroups hyper-v } define service{ use generic-service service_description Hypervisor Virtual Processor Server2 VP3 check_command hv-virtual-processor!Server2:Hv VP 3 host_name HvServer2 servicegroups hyper-v } ##############################################################
