Performance counters to monitor ASP.NET web site performance.

I found it useful to track the following performance counters when monitoring the performance of a web application.

\.NET CLR Interop(WebDev.WebServer)\# of marshalling
\.NET CLR Jit(WebDev.WebServer)\% Time in Jit
\.NET CLR LocksAndThreads(WebDev.WebServer)\Contention Rate / sec
\.NET CLR Memory(WebDev.WebServer)\# Bytes in all Heaps
\.NET CLR Memory(WebDev.WebServer)\Large Object Heap size
\.NET CLR Security(WebDev.WebServer)\% Time in RT checks
\ASP.NET Applications(__Total__)\Requests/Sec
\ASP.NET\Request Execution Time
\ASP.NET\Requests Queued
\Distributed Transaction Coordinator\Transactions/sec
\Memory\Available MBytes
\Memory\Pages/sec
\PhysicalDisk(_Total)\Avg. Disk Queue Length
\Process(sqlservr)\% Processor Time
\Process(WebDev.WebServer)\% Processor Time
\Processor(_Total)\% Processor Time
\SQLServer:Exec Statistics(Average execution time (ms))\DTC calls
\SQLServer:Locks(Database)\Lock Waits/sec
\System\Context Switches/sec
\System\Processor Queue Length
\Web Service(Default Web Site)\Anonymous Users/sec
\Web Service(Default Web Site)\ISAPI Extension Requests/sec
