Cisco SD-WAN by HTTP

Overview

This template is designed for the effortless deployment of Cisco SD-WAN monitoring by Zabbix via HTTP and doesn't require any external scripts.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • Cisco SD-WAN 20.6.0

Configuration

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

Setup

  1. Put your username and password from Cisco SD-WAN vManage into {$SDWAN.API.USERNAME} and {$SDWAN.API.PASSWORD} macros.
  2. Set your Cisco SD-WAN vManage URL as {$SDWAN.API.URL} macro value.

NOTES

The Cisco SD-WAN API token will be generated automatically by the Authentication item every {$SDWAN.AUTH.FREQUENCY}. Don't change the {$SDWAN.AUTH.FREQUENCY} macro value if it's not required.

The generated Cisco SD-WAN API token and the session ID will be used in all Cisco SD-WAN templates and items. These values will be kept in {$SDWAN.AUTH.TOKEN} and {$SDWAN.AUTH.SESSION} macros of each discovered host.

IMPORTANT

Values of {$SDWAN.AUTH.TOKEN} and {$SDWAN.AUTH.SESSION} macros are stored as plain (not secret) text by default.

Please, refer to the vendor documentation about the Cisco SD-WAN REST API Token-Based Authentication.

Macros used

Name Description Default
{$SDWAN.API.URL}

Cisco SD-WAN Monitor API URL.
{$SDWAN.API.USERNAME}

Cisco SD-WAN Monitor API username.
{$SDWAN.API.PASSWORD}

Cisco SD-WAN Monitor API password.
{$SDWAN.AUTH.FREQUENCY}

The update interval for the Cisco SD-WAN Authentication item, which also equals the access token regeneration request frequency. Check the template documentation notes carefully for more details.

 1h
{$SDWAN.DATA.TIMEOUT}

A response timeout for an API.

 15s
{$SDWAN.DEVICE.NAME.MATCHES}

This macro is used in device discovery. Can be overridden on the host or linked template level.

 .*
{$SDWAN.DEVICE.NAME.NOT_MATCHES}

This macro is used in device discovery. Can be overridden on the host or linked template level.

 CHANGE_IF_NEEDED
{$SDWAN.HTTP_PROXY}

HTTP proxy for API requests. You can specify it using the format [protocol://][username[:password]@]proxy.example.com[:port]. See the documentation at https://www.zabbix.com/documentation/7.0/manual/config/items/itemtypes/http

Items

Name Description Type Key and additional info
SD-WAN: Authentication

This trigger expression works as follows:
1. It can be triggered if the operational status is down.
2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the operational status was up to (1) sometime before (so, it does not fire for the 'eternal off' interfaces).
