macOS by Zabbix agent

Overview

This is an official MacOS 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.

Requirements

Zabbix version: 7.4 and higher.

Tested versions

This template has been tested on:

  • macOS operating system

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Install Zabbix agent on macOS according to Zabbix documentation.
