Network I/O Log Based Metrics

The netif input plugin gathers network traffic information of the running system every certain interval of time, and reports them.

The Network I/O Metrics plugin creates metrics that are log-based (I.e. JSON payload). If you are looking for Prometheus-based metrics please see the Node Exporter Metrics input plugin.

Configuration Parameters

The plugin supports the following configuration parameters:

Key
Description
Default

Interface

Specify the network interface to monitor. e.g. eth0

Interval_Sec

Polling interval (seconds).

1

Interval_NSec

Polling interval (nanosecond).

0

Verbose

If true, gather metrics precisely.

false

Test_At_Init

If true, testing if the network interface is valid at initialization.

false

Getting Started

In order to monitor network traffic from your system, you can run the plugin from the command line or through the configuration file:

Command Line

$ bin/fluent-bit -i netif -p interface=eth0 -o stdout

Configuration File

In your main configuration file append the following Input & Output sections:

[INPUT]
    Name          netif
    Tag           netif
    Interval_Sec  1
    Interval_NSec 0
    Interface     eth0
[OUTPUT]
    Name   stdout
    Match  *

Note: Total interval (sec) = Interval_Sec + (Interval_Nsec / 1000000000).

e.g. 1.5s = 1s + 500000000ns
