WireGuard

Plugin: go.d.plugin Module: wireguard

Overview

This collector monitors WireGuard VPN devices and peers traffic.

It connects to the local WireGuard instance using wireguard-go client.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

This collector requires the CAP_NET_ADMIN capability, but it is set automatically during installation, so no manual configuration is needed.

Default Behavior

Auto-Detection

It automatically detects instances running on localhost.

Limits

Doesn't work if Netdata or WireGuard is installed in the container.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

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 device

These metrics refer to the VPN network interface.

Labels:

Label	Description
device	VPN network interface

Metrics:

Metric	Dimensions	Unit
wireguard.device_network_io	receive, transmit	B/s
wireguard.device_peers	peers	peers

Per peer

These metrics refer to the VPN peer.

Labels:

Label	Description
device	VPN network interface
public_key	Public key of a peer

Metrics:

Metric	Dimensions	Unit
wireguard.peer_network_io	receive, transmit	B/s
wireguard.peer_latest_handshake_ago	time	seconds

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is go.d/wireguard.conf.

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 go.d/wireguard.conf

Options

The following options can be defined globally: update_every, autodetection_retry.

Config options

Name	Description	Default	Required
update_every	Data collection frequency.	1	no
autodetection_retry	Recheck interval in seconds. Zero means no recheck will be scheduled.	0	no

Examples

There are no configuration examples.

Troubleshooting

Debug Mode

To troubleshoot issues with the wireguard collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m wireguard
