IIS Monitoring on Windows 2016 or earlier

Note

This section does NOT apply if you are using version 6.2.2.0 or later.

To Monitor the IIS, ensure the agent has all the Prerequisites installed.

On Windows Server 2016 or earlier, the system has Microsoft.Web.Administration in Assembly version 7.0.0.0 which in turned uses .NET Framework 2.0. The Agent ship with a much newer version.

In a Monitor View, the IIS resource is in the Unavailable state.

To solve this, follow the steps below:

Note

These steps are Manual and must be applied each time the Agent is updated.

  1. Stop the Agent.
  2. Remove the Microsoft.Web.Administration.dll file in the installation folder of the agent.
  3. Copy the Microsoft.Web.Administration.dll from C:\Windows\assembly\GAC_MSIL\Microsoft.Web.Administration\7.0.0.0__31bf3856ad364e35 folder to the installation folder of the Agent.
  4. Edit the Nodinite.MonitoringAgent.WindowsServerHost.exe.config file using Notepad++ and add the following assembly redirect section:
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
            <assemblyIdentity name="Microsoft.Web.Administration" publicKeyToken="31bf3856ad364e35" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-10.0.0.0" newVersion="7.0.0.0" />
        </dependentAssembly>
    </assemblyBinding>

If this is the case, you should try the assembly redirect option as documented on this page.

  1. Start the Agent.
