Configuration Parameters
The plugin supports the following configuration parameters:
Key
Description
Interface
Specify the network interface to monitor. e.g. eth0
Interval_Sec
Polling interval (seconds).  default: 1
Interval_NSec
Polling interval (nanosecond). default: 0
Verbose
If true, gather metrics precisely. default: 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
