About this Hands-on Lab

In this lab, you have been provided with a Linux server that has Fluent Bit preinstalled. Fluent Bit has been configured as a standard Fluentd installation. Your task is to create a Fluent Bit configuration that will poll the CPU every five seconds. You will manually run this configuration using the `fluent-bit` command and the `-c` option. The output should be sent to the stdout for Fluent Bit.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create the Configuration File

Create a file called cpu-stats.conf in the home folder. In this file, you will create a configuration that uses the cpu plugin to read metrics. You will also set a global configuration to flush the metrics to the output plugin every five seconds. You will set the output plugin to be the stdout plugin.

Run the Configuration Manually

Using the fluent-bit –c cpu-stats.conf option, you will run the configuration you just created.

Check the Statistics Are Showing

Examine the output that is going to stdout and ensure that the CPU statistics are being sent to stdout every five seconds.

Do not be concerned if it takes a little over or under five seconds for the output to be shown.

Additional Resources

You have been told that you can use a small footprint version of Fluentd called Fluent Bit that can be used to obtain metrics from computers. Your goal is to find software that can be used on your IOT devices to send various metrics elsewhere, and you have been told this software is suitable. You have a server that will work as a test platform for this task, and Fluent Bit has been preinstalled for you.

Your task is to create a configuration file that will use the Fluent Bit plugin called cpu to poll the CPU every five seconds. You will use the stdout plugin to send this output to the stdout for Fluent Bit.
