# IIS by Zabbix agent

## Overview

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

## Requirements

Zabbix version: 7.0 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](https://www.zabbix.com/documentation/7.0/manual/config/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
```text
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.<br>
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|
|----|-----------|-------|
|{$IIS.PORT}|<p>Listening port.</p>|`80`|
|{$IIS.SERVICE}|<p>The service (http/https/etc) for port check. See "net.tcp.service" documentation page for more information: https://www.zabbix.com/documentation/7.0/manual/config/items/itemtypes/simple_checks</p>|`http`|
|{$IIS.QUEUE.MAX.WARN}|<p>Maximum application pool's request queue length for trigger expression.</p>||
|{$IIS.QUEUE.MAX.TIME}|<p>The time during which the queue length may exceed the threshold.</p>|`5m`|
|{$IIS.APPPOOL.NOT_MATCHES}|<p>This macro is used in application pools discovery. Can be overridden on the host or linked template level.</p>|`<CHANGE_IF_NEEDED>`|
|{$IIS.APPPOOL.MATCHES}|<p>This macro is used in application pools discovery. Can be overridden on the host or linked template level.</p>|`.+`|
|{$IIS.APPPOOL.MONITORED}|<p>Monitoring status for discovered application pools. Use context to avoid trigger firing for specific application pools. "1" - enabled, "0" - disabled.</p>|`1`|
