IIS by Zabbix agent

Overview

The template to monitor IIS (Internet Information Services) by Zabbix that works without any external scripts.

Requirements

Zabbix version: 7.4 and higher.

Tested versions

This template has been tested on:

  • Windows Server 2012R2

Configuration

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

Setup

You have to enable the following Windows Features (Control Panel > Programs and Features > Turn Windows features on or off) on your server

Web Server (IIS)
Web Server (IIS)\Management Tools\IIS Management Scripts and Tools

Optionally, it is possible to customize the template:

  • Set value for the macro {$IIS.QUEUE.MAX.WARN}, if you want to receive alerts when a number of requests in the application pool queue exceeds the threshold.
  • If you use a non-standard port for the IIS, don't forget to update the macros {$IIS.SERVICE} and {$IIS.PORT}.
  • Change the value of macro {$IIS.APPPOOL.MONITORED} to "0", if you want to disable all notifications about application pools state.
    You can also add additional context macro {$IIS.APPPOOL.MONITORED:<AppPoolName>} for excluding specific application pools from monitoring.
  • Change regexp in the macros {$IIS.APPPOOL.MATCHES} and {$IIS.APPPOOL.NOT_MATCHES} used for filtering application pools discovery results.

Macros used

Name Description Default
{$IIS.PORT}

Listening port.

 80
{$IIS.SERVICE}

The service (http/https/etc) for port check. See "net.tcp.service" documentation page for more information: https://www.zabbix.com/documentation/7.4/manual/config/items/itemtypes/simple_checks

 http
{$IIS.QUEUE.MAX.WARN}

Maximum application pool's request queue length for trigger expression.
{$IIS.QUEUE.MAX.TIME}

The time during which the queue length may exceed the threshold.

 5m
{$IIS.APPPOOL.NOT_MATCHES}

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

 <CHANGE_IF_NEEDED>
{$IIS.APPPOOL.MATCHES}

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

 .+
{$IIS.APPPOOL.MONITORED}

Monitoring status for discovered application pools. Use context to avoid trigger firing for specific application pools. "1" - enabled, "0" - disabled.

Items

Name Description Type Key and additional info
World Wide Web Publishing Service (W3SVC) state

The World Wide Web Publishing Service (W3SVC) provides web connectivity and administration of websites through the IIS snap-in. If the World Wide Web Publishing Service stops, the operating system cannot serve any form of web request. This service was dependent on "Windows Process Activation Service".

Windows Process Activation Service (WAS) is a tool for managing worker processes that contain applications that host Windows Communication Foundation (WCF) services. Worker processes handle requests that are sent to a Web Server for specific application pools. Each application pool sets boundaries for the applications it contains.
