Monitoring Hyper-V via Telegraf

Now the cool thing about Telegraf on Windows is that you can basically monitor any system service that reports to the Windows performance counters. So creating a Hyper-V dashboard is actually fairly easy.

Create a new input configuration file in the telegraf.d directory:

# PowerShell
notepad C:\telegraf\telegraf.d\hyperv.conf

Paste the following into your new file, then save.

[[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Virtual Machine Health Summary"
    Instances = ["------"]
    Measurement = "hyperv_health"
    Counters = [
      "Health Ok",
      "Health Critical",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Hypervisor"
    Instances = ["------"]
    Measurement = "hyperv_hypervisor"
    Counters = [
      "Logical Processors",
      "Partitions",
    ]

    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Hypervisor Virtual Processor"
    Instances = ["*"]
    Measurement = "hyperv_processor"
    Counters = [
      "% Guest Run Time",
      "% Hypervisor Run Time",
      "% Idle Time",
      "% Total Run Time",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Dynamic Memory VM"
    Instances = ["*"]
    Measurement = "hyperv_dynamic_memory"
    Counters = [
      "Current Pressure",
      "Guest Visible Physical Memory",
    ]

    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V VM Vid Partition"
    Instances = ["*"]
    Measurement = "hyperv_vid"
    Counters = [
      "Physical Pages Allocated",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Virtual Switch"
    Instances = ["*"]
    Measurement = "hyperv_vswitch"
    Counters = [
      "Bytes Received/Sec",
      "Bytes Sent/Sec",
      "Packets Received/Sec",
      "Packets Sent/Sec",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Virtual Network Adapter"
    Instances = ["*"]
    Measurement = "hyperv_vmnet"
    Counters = [
      "Bytes Received/Sec",
      "Bytes Sent/Sec",
      "Packets Received/Sec",
      "Packets Sent/Sec",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Virtual IDE Controller"
    Instances = ["*"]
    Measurement = "hyperv_vmdisk"
    Counters = [
      "Read Bytes/Sec",
      "Write Bytes/Sec",
      "Read Sectors/Sec",
      "Write Sectors/Sec",
    ]
    
    [[inputs.win_perf_counters.object]]
    ObjectName = "Hyper-V Virtual Storage Device"
    Instances = ["*"]
    Measurement = "hyperv_storage"
    Counters = [
      "Write Operations/Sec",
      "Read Operations/Sec",
      "Read Bytes/Sec",
      "Write Bytes/Sec",
      "Latency",
      "Throughput",
    ]

Restart Telegraf with the new config file.

# PowerShell Administrator
net stop telegraf
net start telegraf

Import dashboard ID: 2618 into Grafana and set your data source to telegraf.
