Description

Fluent Bit input plugin that collects CPU metrics from Linux hosts.

This plugin will only work on hosts running Linux, because it relies on /proc/stat files from Procfs.

Requirements

• Docker
• Docker image fluent-beats/fluent-bit-plugin-dev

Build

./build.sh

Test

./test.sh

Design

This plugin was desined to collect data from any mounted Linux stat proc file.

It can be used to collect overall CPU or process CPU usage, even if Fluent Bit is running inside a container, which is not achievable using native Fluent Bit cpu plugin.

Potentially LXCFS could bypass that without requiring a custom plugin

Configurations

This input plugin can be configured using the following parameters:

Key	Description	Default
interval_sec	Interval in seconds to collect data	1
interval_nsec	Interval in nanoseconds to collect data	0
proc_path	Path to look for net file	/proc
pid	Specify the ID (PID) of a running process in the system. By default the plugin monitors the whole system but if this option is set, it will only monitor the given process ID.
