Starting a Message Analyzer Session

The basic unit of workflow and starting point of all Message Analyzer operations is a session. A session is the instrument that you will configure and then use to collect data that you want to analyze, whether you capture it live on a network or load it into Message Analyzer from saved message files, logs, or other sources. The user interface (UI) for configuring a new session is designed to provide an optimal workflow experience and enables you to utilize essentially two types of Message Analyzer sessions to acquire input data, as follows:

  • Live Trace Session — enables you to specify a session configuration that captures message data live from network traffic, system components, or devices.

  • Data Retrieval Session — enables you to specify a session configuration that acquires input message data from multiple disparate data sources, such as saved files, logs, and others.

Streamlining Session Input Workflow
The Message Analyzer UI provides a streamlined input workflow architecture that is designed to support expansive data collection capabilities, which includes the future addition of new data sources. Currently, Message Analyzer data collection capabilities include the simultaneous capture of live data from a local host and/or multiple remote target computers, as described in Configuring a Live Trace Session, Configuring a Remote Capture, and Configuring Session Scenarios with Selected Data Sources; in addition to retrieval of data from multiple saved data sources, as described in Locating Supported Input Data File Types and Acquiring Data From Other Input Sources.

Message Analyzer also provides an integrated session configuration workflow that minimizes the number of clicks and dialogs you need to get a Live Trace Session or a Data Retrieval Session running, while making configuration features that are common to both session types readily accessible and easy to configure.

Configuring a New Session: Overview
All of the foregoing capabilities are unified through the use of a common interface that is called the New Session dialog. This dialog is accessible by clicking the New Session item in the Message Analyzer File menu, or by simply clicking the New Session button on the Message Analyzer Start Page or on the global Message Analyzer toolbar. From the New Session dialog, you can choose the type of session you want to start, such as a Live Trace Session or a Data Retrieval Session:

  • Live Trace Session — you can begin the configuration of a Live Trace Session by clicking the Live Trace button under Add Data Source in the New Session dialog. The configuration features that are unique to this type of session enable you to do the following:

    • Target local and/or remote computers from which to capture live data with the use of the Edit Target Computers dialog, which is accessible by clicking the Edit button next to the Target Computers text box, as described in Configuring a Remote Capture.

    • Choose a built-in Trace Scenario from the Select Scenario drop-down list that includes one or more message providers that capture network messages through different stack layers, or from system components and other devices, as described in Selecting a Trace Scenario.

    • Add one or more system ETW Providers to any Trace Scenario to enhance the scope of data retrieval, by selecting them from the Add Providers drop-down list, as described in Adding a System ETW Provider.

    • Specify various filtering configurations for message providers, including Fast Filters, WFP Layer Set filters in Trace Scenarios that use the Microsoft-PEF-WFP-MessageProvider; event Keyword and error Level filters; adapter filters and logically chained Fast Filter groups in Local Network Interfaces traces; NDIS stack, Hyper-V-Switch extension layer, and other special filters in traces that use the Microsoft-Windows-NDIS-PacketCapture provider, for example Remote Network Interfaces traces that have remote capture capability; and so on, as described in Configuring a Live Trace Session.

    • Specify ETW Session Configuration parameters to control performance of the underlying ETW sessions in all traces, as described in Specifying Advanced ETW Session Configuration Settings.

  • Data Retrieval Session — you can begin the configuration of a Data Retrieval Session by clicking the Files button under Add Data Source in the New Session dialog. The configuration features that are unique to this type of session enable you to do the following:

The configuration features of the New Session dialog that are common to both session types enable you to do the following:

  • Specify a Session Filter that limits the data you capture or retrieve based on specific filtering criteria.

  • Select a Parsing Level to limit how far up the stack Message Analyzer will parse, for better performance and focused message sets, as described in Setting the Session Parsing Level.

  • Choose a data viewer in which to display your trace results by selecting one in the Start With drop-down list, or use the default viewer setting, as described in Selecting a Session Data Viewer.

  • Provide a Name for the new session, as described in Naming a Session.

Using Session Options
The New Session item in the Message Analyzer File menu provides the following submenu items as options for creating a session:

  • Blank Session — creates an unconfigured new session.

  • From Current Session — creates a new session based on the configuration of a currently open and selected session.

Creating a New Session: Workflow Overview
To familiarize yourself with the workflow you will generally follow when creating a basic session configuration, follow the steps below to create a session that captures data live or retrieves data from saved files and logs:

General Workflow Process

  1. From the Start menu, Start page, or task bar of your computer, click the Microsoft Message Analyzer icon to launch Message Analyzer. If you have not logged off and back on after first installing Message Analyzer, then restart Message Analyzer and use the right-click Run as Administrator option.

  2. Click the New Session button on the Message Analyzer Start Page to display the New Session dialog.

    Alternatively, click the New Session item in the Message Analyzer File menu to display the New Session dialog.

  3. To start session configuration, do one of the following under Add Data Source in the New Session dialog:

    • Click the Live Trace button to display the Live Trace tab along with the associated session configuration features that it contains in the New Session dialog, to begin configuration of a Live Trace Session.

    • Click the Files button to display the Files tab along with the associated session configuration features that it contains in the New Session dialog, to begin configuration of a Data Retrieval Session.

  4. If you chose to configure a Live Trace Session, do the following to create a basic configuration; otherwise, proceed to step 5:

    • Use the default Localhost setting in the Target Computers list on the Live Trace tab of the New Session dialog, to capture data from the local computer only.

    • Choose a built-in Trace Scenario in the Select Scenario drop-down list on the ETW Providers toolbar of the Live Trace tab to define the scope of the data you will capture.

    • Optionally, select a built-in Filter Expression from the Library drop-down list on the toolbar above the Session Filter text box to create a Session Filter that narrows the scope of data capture, so you can focus on a specific type of data in your trace results.

    • Choose a data viewer in which to display the results of your Live Trace Session by selecting it in the Start With drop-down list of the New Session dialog; or accept the default setting.

    • To review additional configuration options for a Live Trace Session, see Configuring a Live Trace Session.

  5. If you chose to configure a Data Retrieval Session, do the following to create a basic configuration:

    • Navigate to the trace or log files that contain the data you want to load into Message Analyzer by clicking the Add Files button on the toolbar of the Files tab in the New Session dialog; this action launches the Open dialog.

    • From the Open dialog, locate and select the files that contain the data to be loaded into Message Analyzer. Click Open to exit the dialog.

      The file names appear in the files list on the Files tab. Note that this list indicates only the supported files that are targeted for file reads during the data loading process, given that at this point, no data has yet been loaded into Message Analyzer.

    • Optionally, select specific files in the files list on the Files tab of the New Session dialog to create a collection of messages to be loaded from a specified subset of files.

    • Optionally, configure a Time Filter to define a window of time in which to retrieve data and create focus on a smaller and targeted set of retrieved messages for enhanced analysis.

    • Optionally, select a built-in Filter Expression from the Library drop-down list on the toolbar above the Session Filter text box to create a Session Filter that narrows the scope of data retrieval, so you can focus on a specific type of data in your retrieved results.

    • To review additional configuration options for a Data Retrieval Session, see Configuring a Data Retrieval Session.
