Hyper-V
Plugin: windows.plugin
Module: PerflibHyperV
Overview
This collector monitors Hyper-V virtualization metrics including virtual machine health status, root partition virtualization layer statistics (TLB flushes, address spaces, attached devices, GPA space), per-VM CPU usage, memory allocation and pressure, storage device I/O and errors, network interface traffic and packets, and virtual switch traffic, packets, and dropped packets.
It queries the ‘HyperV’ object from Perflib in order to gather the metrics.
This collector is only supported on the following platforms:
This collector only supports collecting metrics from a single instance of this integration.
Default Behavior
Auto-Detection
The collector automatically detects all of the metrics, no further configuration is required.
Limits
The default configuration for this integration does not impose any limits on data collection.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
No action required.
Configuration
Options
| Option | Description | Default | Required |
|---|
| update every | Data collection frequency. | 5 | no |
via File
The configuration file name for this integration is netdata.conf.
Configuration for this specific integration is located in the [plugin:windows:PerflibHyperV] section within that file.
The file format is a modified INI syntax. The general structure is:
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf
Examples
There are no configuration examples.
Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
