Random

Random input plugin generate very simple random value samples using the device interface /dev/urandom, if not available it will use a unix timestamp as value.

Configuration Parameters

The plugin supports the following configuration parameters:

Key	Description
Samples	If set, it will only generate a specific number of samples. By default this value is set to -1, which will generate unlimited samples.
Interval_Sec	Interval in seconds between samples generation. Default value is 1.
Internal_Nsec	Specify a nanoseconds interval for samples generation, it works in conjuntion with the Interval_Sec configuration key. Default value is 0.

Getting Started

In order to start generating random samples, you can run the plugin from the command line or through the configuration file:

Command Line

From the command line you can let Fluent Bit generate the samples with the following options:

$ fluent-bit -i random -o stdout

Configuration File

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

[INPUT]
    Name          random
    Samples      -1
    Interval_Sec  1
    Interval_NSec 0

[OUTPUT]
    Name   stdout
    Match  *
