## Overview

This is an official Linux template. It requires Zabbix agent 7.4 or newer.

#### Notes on filesystem (FS) discovery:
- The ext4/3/2 FS reserves space for privileged usage, typically set at 5% by default.
- BTRFS allocates a default of 10% of the volume for its own needs.
- To mitigate potential disasters, FS usage triggers are based on the maximum available space.
  - Utilization formula: `pused = 100 - 100 * (available / total - free + available)`
- The FS utilization chart, derived from graph prototypes, reflects FS reserved space as the difference between used and available space from the total volume.
