Attributes and Elements

The following sections describe attributes, child elements, and parent elements for this section.

Attributes

statusCodes

Optional string attribute.

Specifies the status code(s) you want to trace. You can enter multiple status codes in this list by using commas to separate each code. You can also refine your status codes using sub status codes, such as "404.2, 500" or a range of sub status codes such as "400-599". If you do not specify substatus codes, all substatus codes for the given status code will be traced. Status codes must be from 100 to 999, and substatus codes must be from 1 to 999.

timeTaken

Optional timeSpan attribute.

Specifies the maximum time that a request may spend in processing before it is marked as failed and then traced.

The default value is 00:00:00.

verbosity

Optional enum attribute.

Specifies the minimum amount of information and the type of information that is saved to the trace log. If the verbosity is set to Error, a failed request trace log file for the request will be created when the first trace event whose verbosity is either Error or CriticalError is received.

The verbosity attribute can be one of the following possible values.

The default value is Ignore.

Value	Description
Ignore	Provides no information about the request activity. The numeric value is 0.
CriticalError	Provides information about actions that can cause a process to exit or that are about to cause a process to exit. The numeric value is 1.
