Open trace log file failed

The problem that you are generating causes a security error trace event to be thrown. However, because the FREB. Under Verbosity , select Verbose. Click Finish. You should see the following definition for the Default Web Site :. The configuration should look as follows:. In this task, you will generate a failed request and view the resulting trace log. Now verify that it works. Notice a few things here: When IIS writes the failed request log file, it writes one file per failed request.

A freb. This helps when you view the resulting failure request log files such as fr Right-click the log file for the If this is the first time that you are opening a Failed Request Tracing file, you must add about:internet to the list of trusted sites, since Internet Explorer's Enhanced Security Configuration is enabled by default. If this is the case, you will see the following:. The following is an example:. In this example, the name and type of the trace listener is specified.

The Listener is named sdt and the standard. NET Framework trace listener System. XmlWriterTraceListener is added as the type. The initializeData attribute is used to set the name of the log file for that Listener to be SdrConfigExample.

For the log file, you can substitute a fully-qualified path for a simple file name. The example creates a file in the root directory called SdrConfigExample. The tracing level is controlled by the switchValue setting. The available tracing levels are described in the following table. You can use add to specify the name and type of the trace listener you want to use.

In the example configuration, the Listener is named sdt and the standard. Use initializeData to set the name of the log file for that Listener. In addition, you can substitute a fully-qualified path for a simple file name. Starting in. NET Framework 4. You can disable this change by removing the following setting from the svcTraceViewer.

Service Trace Viewer enables you to open any supported trace file, add and integrate additional trace files, or open and merge a group of trace files simultaneously. The Service Trace Viewer tool can associate with two file types:. You can use two parameters in command line to register and unregister the file extensions. Navigate to the location where your trace files are stored.

Service Trace Viewer merges the content of all files and presents one view. For example, you can open trace files of both client and service. This is useful when you have enabled message logging and activity propagation in configuration.

In this way, you can examine message exchange between client and service. You can also drag multiple files into the viewer, or use the Project tab. See the Managing Project section for more details. To add additional trace files to the collection that is open, click File and then point to Add.

In the window that opens, navigate to the location of the trace files and double-click the file you want to add. It is not recommended that you load a trace log file bigger than MB. If you attempt to load a file larger than this limit, the loading process may take a long time, depending on your computer resource. The Service Trace Viewer tool may not be responsive for a long time, or it may exhaust your machine's memory. It is recommended that you configure partial loading to avoid this. For more information on how to do this, see "Loading Large Trace Files" section.

The viewer's native format is the activity tracing format that WCF emits. Traces emitted in a different format must be converted before the viewer displays them.

Currently, in addition to the activity tracing format, the viewer supports event tracing and crimson tracing. When you open a file that does not contain activity traces, the viewer attempts to convert the file.

You must specify the name and location of the file that will contain the converted trace data. Once the data has been converted, the viewer displays the content of the new file. Conversion requires disk space to store the converted trace data. Make sure you have enough disk space available to store the data before you start a conversion. Otherwise, the conversion fails.

The viewer supports projects to facilitate viewing multiple trace files. For example, if you have a client trace file and a service trace file, you can add them to a project.

Then, every time you open the project, all the trace files in the project are loaded simultaneously. WCF emits traces using the activity tracing format. In the activity tracing model, individual traces are grouped in activities according to their purpose. Logical control flow is transferred between activities. For example, during the lifetime of an application, many "message send activities" appear and disappear. The Service Trace Viewer provides the following different views.

They are displayed as tabs on the left pane of the Viewer, and can also be accessed from the View menu. Once the trace files are opened, you can see the traces grouped into activities and displayed in the Activity view in the left-hand pane. The Activity view displays activity names, number of traces in the activity, duration time, start time and end time. By clicking any of the listed activities, the traces in this activity are displayed in the trace pane on the right.

You can then select a trace to view its details. You can select multiple activities by pressing the Ctrl or Shift key and clicking the desired activities.

The trace pane displays all the traces of the selected activities. You can double-click an activity to display it in Graph View. The alternative way is to select an activity and switch to Graph View.

The activity "" is a special activity that cannot be displayed in the Graph View. Because all other activities are linked to it, displaying this activity has a severe performance impact. You can click the column title to sort the activity list. Activities that contain warning traces have a yellow background and those that contain error traces have a red one.

There are different types of activities and each type corresponds to an icon on the left side of each activity.

You can refer to the Understanding Trace Icons section for their meaning. This view enables you to manage trace files in the current project. This view displays the trace data for a given activity in chart form. The chart form enables you to see the stepwise execution of events and the interrelationships between multiple activities as data moves between them.

To switch to Graph view, select an activity in the Activity view and click the Activity tab, or a message log trace in the Message View. If multiple trace files are loaded and the activity involves traces from more than one file, all of the relevant traces appear in the graph view. Double-clicking on the activities and message log traces also leads you to the Graph view. In Graph view, each vertical column represents an activity, and each block in the column represents a trace.

The activities are grouped by process or thread. When you use TraceView to display a trace log, it uses the default session name, LogSession N , as the name of the trace session where N is a zero-based integer that represents the order in which the session is created.
