- Hyper-V Hypervisor Root Virtual Processor(_Total)\% Guest Run Time
- Hyper-V Hypervisor Root Virtual Processor(_Total)\% Hypervisor Run Time
- Hyper-V Hypervisor Root Virtual Processor(_Total)\% Remote Run Time
- Hyper-V Hypervisor Root Virtual Processor(_Total)\% Total Run Time
- Hyper-V Hypervisor Virtual Processor(_Total)\% Guest Run Time

Usage

Import provided templates.
Allow Zabbix to create necessary groups. (Just to check that everything works as expected. You can modify all the details to suit your needs later.)
Copy provided PowerShell script to the desired location on your HyperV host machine. If your server(s) are not running a english version of windows, you will have to modify the performance counters to match the names in the server OS language.

Assuming your host is called my-hyperv-hostname, you can create a self siged certificate and sign it as follow:

Set-AuthenticodeSignature -Certificate $cert -FilePath 'C:\Program Files\Zabbix Agent 2\zabbix-vm-perf.ps1
$exportPath = "C:\myCert.cer"
Export-Certificate -Cert $cert -FilePath $exportPath
Import-Certificate -FilePath $exportPath -CertStoreLocation Cert:\LocalMachine\TrustedPublisher
Import-Certificate -FilePath $exportPath -CertStoreLocation Cert:\LocalMachine\Root
Remove-Item -Path $exportPath

In case you don't care about security, you can lower the restrictions If you downloaded the script from internet, then make sure windows is not blocking it.

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope LocalMachine
Put the file hyper-v.conf in C:\Program files\Zabbix Agent 2\zabbix_agentd.d Adjust the paths according to the previous step if needed
Restart zabbix agent.
Set-up Hyper-V host in Zabbix interface.
- Add a new host, if needed.
- Link it with "Template Windows HyperV Host" template.
- Wait for a guest discovery to fire, it will:
  - discover Hyper-V guests,
  - create a new host for each VM,
  - put discovered VM host into "Hyper-V VM" group,
  - link VM host with "Template Windows HyperV VM Guest"
Go to the Hyper-V host in the Zabbix interface and click on the discoveries, and click on test.
- If you get an error check
  - If your certificate is signed/you changed the policy to unrestricted.
  - If your path in the config file is correct.
```
Provide the path to an existing '.ps1' file as an argument to the -File parameter.

F.A.Q.

Depending on the load of your Hyper-V server, you will have to increase the default Zabbix Temout from 3 to 10-30 seconds
