Description

Fluent Bit input plugin that collects network usage information from Linux hosts.

This plugin will only work on hosts running Linux, because it relies on /proc/net/dev file from Procfs.

Requirements

• Docker
• Docker image fluent-beats/fluent-bit-plugin-dev

Build

./build.sh

Test

./test.sh

Design

This plugin was desined to collect data from any mounted Linux network proc file.

It can be used to collect host network usage info, even if Fluent Bit is running inside a container, which is not achievable using native Fluent Bit netif plugin.

Potentially LXCFS could bypass that without requiring a custom plugin

Configurations

This input plugin can be configured using the following parameters:

Key	Description	Default
interface	Specify the network interface to monitor	null
interval_sec	Interval in seconds to collect data	1
interval_nsec	Interval in nanoseconds to collect data	0
proc_path	Path to look for net file	/proc
verbose	If true, gather metrics precisely	false
