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 conjunction 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:

  1. $ fluent-bit -i random -o stdout

Configuration File

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

  1. [INPUT]
  2.     Name          random
  3.     Samples      -1
  4.     Interval_Sec  1
  5.     Interval_NSec 0
  7. [OUTPUT]
  8.     Name   stdout
  9.     Match  *

Testing

Once Fluent Bit is running, you will see the reports in the output interface similar to this:

  1. $ fluent-bit -i random -o stdout
  2. Fluent Bit v1.x.x
