Health and Diagnostics provides an infrastructure to monitor, manage, and troubleshoot the health of a web server, sites, and applications.
The advantage is the detailed trace events that track a request throughout the complete request-and-response process. To enable the collection of these trace events, IIS Server can be configured to automatically capture full trace logs, in XML format, for any particular request based on elapsed time or error response codes.
Health and diagnostics includes the following features:
- Failed request tracing rules
- Logging
- Worker processes
IIS Health and Diagnostics modules consume extra CPU resources and are often disabled in production IIS environments.
IIS exposes numerous configuration parameters that affect IIS performance. The following are things you need to do if you are looking for more performance; otherwise, keep the default settings:
- Disable IIS logging
- Disable IIS ASP debugging
- Tune the value of the ASP Threads Per Processor Limit property
- Enable IIS HTTP compression
- Configure ASP.NET 4 max ConcurrentRequests
- Disable WCF services tracing
