# Cisco UCS Manager by SNMP

## Overview

Cisco UCS® Manager provides unified, embedded management of all software and hardware components of the Cisco Unified Computing System™ (Cisco UCS) across multiple chassis and rack servers. It enables server, fabric, and storage provisioning as well as,
device discovery, inventory, configuration, diagnostics, monitoring, fault detection, auditing, and statistics collection.
This is a template for Cisco UCS Manager monitoring via Zabbix SNMP Agent that works without any external scripts.
You can download UCS MIB files there ftp://ftp.cisco.com/pub/mibs/ucs-mibs/.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Cisco UCS Manager

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

1. Create a host for Cisco USC Manager IP as SNMPv2 interface.
2. Link the template to the host.
3. Customize macro values if needed.
