The Unified Logging Service (ULS) includes improvements to manageability, log file
improvements, correlation ID tracing, and Windows PowerShell™ scripting. Event
throttling is one of the enhancements to manageability. It is configured on the
Diagnostics Logging page illustrated earlier. Event throttling controls the severity of
events that are captured in the Windows® event log and the trace logs. As the severity
decreases, the number of events logged will increase. Events are categorized, and the
administrator can change the settings for any single category or for all categories.
Updating all categories will lose the changes to individual categories. Event Log Flood
Protection (EVFP) can also be enabled on the same Web page. When EVFP is enabled,
repeating events are detected and suppressed until conditions return to normal. The
ULS now contains all application log events, and third-party logging software can be
integrated into the ULS. The logs have been reduced in size by more than 50 percent by
using the NTFS file system compression. The trace log can also be located in a specified
location, and the storage duration and amount of storage can also be configured.
Correlation IDs that are associated with each request help troubleshoot errors related to
the request. SQL Profiler traces will also show correlation IDs to further assist in the
