IIS

Overview

This plugin collects runtime metrics from Microsoft IIS. The plugin requires Microsoft IIS Administration API to be installed and configured. Plugin gathers information about connections, requests, memory and network statistics, etc. for webserver, application pools and websites. For more information, please refer to IIS Administration API Monitoring.

Setup

The iis plugin is included with the SolarWinds Snap Agent by default, please follow the directions below to enable it for a agent instance.

Prerequisites

This plugin require access token and optionally user credentials to gather status information using IIS Administration API. Refer to IIS Administration API documentation on how to configure API access.

$cred = Get-Credential -Credential <API user>
Invoke-WebRequest -Headers @{"Access-Token"="Bearer <API token>"} -Method GET https://localhost:55539/api/webserver/monitoring/ -Credential $cred | ConvertFrom-Json

Configuration

The agent provides an example configuration file to help you get started quickly. It defines the plugin and task file to be loaded by the agent, but requires you to provide the correct settings for authentication. To enable the plugin:

1. Make a copy of the iis example configuration file iis.yaml.example, renaming it to iis.yaml:

   On Windows, using Explorer or PowerShell:

   copy "C:\ProgramData\SolarWinds\Snap\plugins.d\iis.yaml.example" "C:\ProgramData\SolarWinds\Snap\plugins.d\iis.yaml"

   On Linux using command line:

   sudo cp -p /opt/SolarWinds/Snap/etc/plugins.d/iis.yaml.example /opt/SolarWinds/Snap/etc/plugins.d/iis.yaml

2. Update the iis.yaml configuration file with settings specific to your IIS instance, for example:

   collector:
   iis:
       all:
           url: "https://localhost:55539"
           token: "oolldxQpEvg3Vj_fRlhVF4-Z9IZgGf5bWM2M2cVEPi1TmOlzjFiGWw"
           username: ""
           password: ""
           domain: ""
           
   load:
       plugin: snap-plugin-collector-aoiis.exe
       task: task-aoiis.yaml

   • url specifies URL to connect with IIS Administration API
   • token configured in IIS Administration API for authentication
   • username
     • if left empty, token only authentication will be used
     • otherwise Microsoft Authentication will be used
   • password valid password associated with username
   • domain domain associated with username

3. Restart the agent:

   On Windows command line:

   net stop swisnapd
   net start swisnapd

   On Linux command line:

   sudo service swisnapd restart

4. Enable the IIS plugin in the AppOptics UI

   On the Integrations Page you will see the IIS plugin available if the previous steps were successful. If you do not see the plugin, see Troubleshooting Linux.

   Select the IIS plugin to open the configuration menu in the UI, and enable the plugin.

   You should soon see the iis metrics reported to your dashboard.

Metrics and Tags

The tables below outline the default set of metrics collected by the iis plugin along with the optional metrics available.

Default Metrics

Default Metric Tags

All IIS metrics are tagged with hostname. Instead of using that tag, we recommend using the @host alias. Additionally, all IIS metrics are tagged with IIS webserver ID. Application Pool and Websites metrics are additionally tagged respectively with AppPoolId and WebSiteId .

Optinal metrics can be activated by editing the task yaml. For more information please read the SolarWinds Snap Agent Task File article.
