Solaris OS

Solaris OS

Oracle Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. It superseded the company's earlier SunOS in 1993. In 2010, after the Sun acquisition by Oracle, it was renamed Oracle Solaris.

Solaris by Zabbix agent

Overview

This is an official Solaris OS 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:

  • Solaris OS

Configuration

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

Setup

Install Zabbix agent on Solaris OS according to Zabbix documentation.
