With IPHost Network Monitor you can run WMI Requests Current monitoring of various devices in your network.
To create a WMI monitor for Requests Current, provide host name (it must be a Windows host) and specify custom WQL query:
The current number of requests, including those that are queued, currently executing, or waiting to be written to the client. Under the ASP.NET process model, when this counter exceeds the requestQueueLimit defined in the processModel configuration section, ASP.NET will begin rejecting requests.
