# Mellanox SNMP

## Overview

For Zabbix version: 5.0 and higher  
The updated template for monitoring the Mellanox network switches over SNMP agent. All items collected in one template without any linked templates.

## Setup

Refer to the vendor documentation.

## Zabbix configuration

The template uses context macros for the temperature trigger expression. By default, it uses a macro value like {$TEMP.MAX.CRIT}. To adjust the threshold for a certain sensor you can define context macros on the host level, with a value corresponding to your device specifications, for example: {$TEMP.MAX.CRIT:"MGMT/BOARD_MONITOR"}. Please, read https://www.zabbix.com/documentation/5.0/manual/config/macros/user_macros_context for more detailed info on user context macros.
