Physical and Logical Disk Performance Metrics
Physical and Logical Disk Performance Metrics
Plugin: windows.plugin Module: PerflibStorage
Overview
Detailed statistics for all disk devices and volumes.
It queries ‘LogicalDisk’ and ‘PhysicalDisk’ objects from Perflib in order to gather the metrics.
This collector is only supported on the following platforms:
- windows
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.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
No action required.
Configuration
File
The configuration file name for this integration is netdata.conf.
Configuration for this specific integration is located in the [plugin:windows] 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
Options
| Name | Description | Default | Required |
|---|---|---|---|
| PerflibStorage | An option to enable or disable the data collection. | yes | no |
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.
Per System
These metrics refer to the entire System.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| system.io | reads, writes | KiB/s |
Per Logical Disk
These metrics refer to Logical Disks.
Labels:
| Label | Description |
|---|---|
| mount_point | Drive letter or mount point path assigned by Windows (e.g., ‘C:’, ‘D:'). |
| driver_type | Classification of the disk device (e.g., norootdir, removable, cdrom, ramdisk). |
| filesystem | File system format used on the volume (e.g., NTFS, FAT32). |
| rw_mode | Current read/write permissions status of the volume (read-only access, read and write access). |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| disk.space | avail, used | GiB |
Per Physical Disk
These metrics refer to Physical Disks.
Labels:
| Label | Description |
|---|---|
| mount_point | Drive letter or mount point path assigned by Windows (e.g., ‘C:’, ‘D:'). |
| device | Manufacturer model name. |
| model | The device model. |
| device_id | Unique hardware identifier for the storage device within the system. |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| disk.io | reads, writes | KiB/s |
| disk.avgsz | reads, writes | KiB/operation |
| disk.ops | reads, writes | operations/s |
| disk.split | discards | operations/s |
| disk.await | reads, writes | milliseconds/operation |
| disk.svctm | svctm | milliseconds/operation |
| disk.util | utilization | percent |
| disk.busy | busy | milliseconds |
| disk.iotime | reads, writes | milliseconds/s |
| disk.qops | operations | operations |
Alerts
There are no alerts configured by default for this integration.
