Random

{% hint style="info" %} Supported event types: logs {% endhint %}

The Random input plugin generates random value samples using the device interface /dev/urandom. If that interface is unavailable, it uses a Unix timestamp as a value.

Configuration parameters

The plugin supports the following configuration parameters:

Key	Description	Default
interval_nsec	Set the interval between generated samples, in nanoseconds. This works in conjunction with interval_sec.	0
interval_sec	Set the interval between generated samples, in seconds.	1
samples	Set the number of samples to generate. -1 generates unlimited samples.	-1
threaded	Indicates whether to run this input in its own thread.	false

Get started

To start generating random samples, you can either run the plugin from the command line or through a configuration file.

Command line

Use the following command line options to generate samples.

fluent-bit -i random -o stdout

Configuration file

The following examples are sample configuration files for this input plugin:

{% tabs %} {% tab title="fluent-bit.yaml" %}

pipeline:
  inputs:
    - name: random
      samples: -1
      interval_sec: 1
      interval_nsec: 0

  outputs:
    - name: stdout
      match: '*'

{% endtab %} {% tab title="fluent-bit.conf" %}

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

[OUTPUT]
  Name   stdout
  Match  *

{% endtab %} {% endtabs %}

Testing

After Fluent Bit starts running, it generates reports in the output interface:

$ fluent-bit -i random -o stdout
