Web Infrastructure: Requests currently being authenticated

Microsoft.LS.2013.Monitoring.UnitMonitor.ThresholdPC.WebInfra.PERF_WEBAUTH_UNAUTH_REQUESTS_IN_PROCESSING (UnitMonitor)

Knowledge Base article:

Summary

The number of requests currently in processing by application that have not yet been authenticated or are processed anonymously.

Causes

This value may grow if an application is overloaded because of a large number of requests. It may also represent requests that are waiting on other services to respond or software errors resulting in no response being returned.

Resolutions

If the traffic volume is overloading the server, reduce traffic by adding additional servers to the pool. If the issue is caused by another system or a software error, restart the website and report the problem to Microsoft.
