How to Monitor ASP.NET

Below are recommendations for monitoring ASP.NET performance counters. There are many counters that can be used to monitor ASP.NET; the list below are some of the most suggested counters to monitor. Although these are suggested counters there isn't much on suggested thresholds for them because the number of applications running will vary too widely to get an accurate thresholds. The best practice would be to start monitoring and collecting data for the counters and then set the threshold values at a later date.

ASP.NET Counters

.NET Counters

Counter Path
.NET CLR Exceptions(*)\# of Exceps Thrown / sec
.NET CLR Loading(*)\Current Assemblies
.NET CLR Loading(*)\Bytes in Loader Heap
.NET CLR Memory(*)\Allocated Bytes/sec
.NET CLR Memory(*)\% Time in GC
.NET CLR Memory(*)\# Bytes in all Heaps
.NET CLR Memory(*)\% Time in GC
.NET CLR Memory(*)\# Gen 0 Collections
.NET CLR Memory(*)\# Gen 1 Collections
.NET CLR Memory(*)\# Gen 2 Collections

Other Counters to Monitor

Most technical sources suggest the following performance counters should be monitored with all ASP.NET applications.

Counter Path
Processor Counter\% Processor Time
Memory Counter\Available Mbytes
System Counter\Context Switches/sec
