Internet Information Services (IIS)

Follow the instructions for installing and configuring the Atatus monitoring agent on IIS servers.

Note:
  1. For IIS versions before IIS 10, it is not possible to set environment variables scoped to a specific application pool, so environment variables need to set globally.
  2. application-pool is the name of the Application Pool your application uses. For example, IIS APPPOOL\DefaultAppPool

  • Environment variables need to be set globally.

  • Set environment variables using AppCmd.exe through PowerShell.

  • Download profiler agent from source

  1. .NET Framework

    $appcmd = "$($env:systemroot)\system32\inetsrv\AppCmd.exe"
$appPool = "<application-pool>"
$environment = @{
  COR_ENABLE_PROFILING = "1"
  COR_PROFILER = "{A6C28362-6F75-472A-B36C-50C1644DA40A}"
  COR_PROFILER_PATH = "<extracted directory>\atatus_profiler.dll"
  ATATUS_PROFILER_HOME = "<extracted directory>"
  ATATUS_PROFILER_INTEGRATIONS = "<extracted directory>\integrations.yml"
  COMPlus_LoaderOptimization = "1"
  ATATUS_LICENSE_KEY = "YOUR_LICENSE_KEY"
  ATATUS_APP_NAME = "YOUR_APP_NAME"
}

$environment.Keys | ForEach-Object {
  & $appcmd set config -section:system.applicationHost/applicationPools /+"[name='$appPool'].environmentVariables.[name='$_',value='$($environment[$_])']"
}

  2. .NET Core

    $appcmd = "$($env:systemroot)\system32\inetsrv\AppCmd.exe"
$appPool = "<application-pool>"
$environment = @{
