Network Subsystem
Network Subsystem
Plugin: windows.plugin Module: PerflibNetwork
Overview
Monitor network interface metrics about bandwidth, state, errors and more.
It queries ‘Network Interface’ and ‘Network Adapter’ 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 |
|---|---|---|---|
| PerflibNetwork | 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.

Per network device
These metrics refer to Network Interfaces.

| device | System-assigned network interface identifier. |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| net.net | received, sent | kilobits/s |
| net.packets | received, sent | packets/s |
| net.speed | speed | kilobits/s |
| net.errors | inbound, outbound | errors/s |
| net.drops | inbound, outbound | drops/s |
| net.queue_length | length | packets |
| net.rsc_connections | connections | connections |
| net.rsc_packets | packets | packets/s |

Alerts
The following alerts are available:
| Alert name | On metric | Description |
|---|---|---|
| inbound_packets_dropped_ratio | net.drops | Ratio of inbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| outbound_packets_dropped_ratio | net.drops | Ratio of outbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| 1m_received_traffic_overflow | net.net | Average inbound utilization for the network interface ${label:device} over the last minute |
| 1m_sent_traffic_overflow | net.net | Average outbound utilization for the network interface ${label:device} over the last minute |
| network_interface_output_queue_length | net.queue_length | Output Queue Length on interface ${label:device} should be zero, otherwise there are delays and bottlenecks. |
