Web Service\Current ISAPI Extension Requests/sec Baseline Monitor

Microsoft.Windows.InternetInformationServices.2003.WebServer.WebServiceCurrentISAPIExtensionRequests.Monitor (UnitMonitor)

Knowledge Base article:

Summary

This Baseline Monitor creates baseline performance data for the Web Service\Current ISAPI Extension Requests performance counter.

The Web Service\Current ISAPI Extension Requests performance counter exposes the current number of ISAPI requests being simultaneously processed by the Web service. When this counter deviates from the normal operational baseline, it may indicate an undesirable performance state.

Configuration

This monitor is not configured to generate Alerts. However, state changes will be monitored. To enable Alerting use the Overrides feature to change the alert configuration.

Resolutions

If the measured value for this counter deviates from the normal operational baseline and indicates an undesirable performance state an investigation of the probable cause and source may be required.
