Description

Fluent Bit input plugin that collects disk usage information from Linux hosts.

This plugin will only work on hosts running Linux, because it relies on /proc/diskstats file 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 diskstats proc file.

It can be used to collect host disk stats, even if Fluent Bit is running inside a container, which is not achievable using native Fluent Bit disk 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
dev_name	Device name to limit the target. (e.g. sda). If not set, gathers information from all of disks and partitions.	null
interval_sec	Interval in seconds to collect data	1
interval_nsec	Interval in nanoseconds to collect data	0
proc_path	Path to look for diskstats file	/proc
