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.
Challenge

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.
