Collect .NET Statistic/Calls/sec

Microsoft.SystemCenter.Apm.Transaction.CollectMonitoredRequests (Rule)

Collects .NET Statistic/Calls/sec performance counter

Knowledge Base article:

Summary

This rule collects .NET Statistic Calls / sec performance counter for transactions.

The counter records the number of requests per second that are being processed by a transaction. This counter is incremented when the request reaches the application.

This counter is only available when application performance monitoring is enabled.

Excessively long database calls might be due to either a problem with the server or with the structure and complexity of the query. Long file I/O times might be due to problems with the file server. Web Services performance issues might occur because the Web Service or the server it resides on is down or there is a problem in the Web Service code. Long internal execution times for applications might result from complex or inefficient code.
