How to analyze the server support environment

Downloading the analysis tools

If you are not familiar with the supported environment of the server to install the agent on, download the analysis tools through the following links.

Using the analysis tools

  1. Run the downloaded analysis tools.

    WhaTap System information scanner

  2. Click number 1 Analysis (Scan).

  3. In the number 2 area, check whether the Windows server version is 2012 or later.

  4. In the number 3 area, check whether the versions are IIS 8.0 or later, and .NET Framework 4.5 or later.

  5. Check that the .NET Framework version appears as v4.0 for each site installed in IIS.

    Number 5 is the supported range, but there is no web.config file. In this case, the agent does not work because they are the sites for ASP, PHP, and such that do not use .NET.

  • .NET Framework supports up to the version 4.8.1.

  • Core, .NET 5, or later is not supported. The .NET Core versions are under development.

Checking the user's application version

Even if the server environment satisfies the supported version, the .NET monitoring is not supported when the user's application has been developed as a .NET Core version instead of .NET Framework.

The user's application version can be seen in the IIS Manager as follows.

IIS Manager

In IIS Manager, click Application Pools. In the Application Pools list, check that .NET of the pool for your available application is the version 4.0.
