Managing Session Filters
Session Filter management features enable you to create, modify, delete, import, export, and share filters. These same management features apply to all Message Analyzer asset collections that you typically work with, such as Color Rules, view Filters, viewer Layouts, Viewpoints, Trace Scenarios, Chart View Layouts, Pattern Expressions, and so on.
Using the Edit Filter Dialog
When you are configuring a Live Trace Session, you have the option to select or create a Session Filter, as described in Working with Session Filters in a Live Trace Session. To create and save a new Filter Expression that you can use as a Session Filter or view Filter, you must open the Edit Filter dialog by selecting the New Filter item from the Library drop-down list above the Session Filter text box in the New Session dialog. In a similar manner, you can also access the Edit Filter dialog from the Library in any Filter panel that displays on the Message Analyzer Filtering toolbar during an Analysis Session to create a new Filter Expression. However, you can also create a Session Filter from the Manage Filter dialog by modifying a copy of an existing Filter Expression; the Manage Filters dialog is accessible by clicking the Manage Filters item in the Library drop-down list in either of the indicated locations. In either case, you end up displaying the same Edit Filter dialog; the only difference is in how you get there. The Edit Filter dialog is shown in the figure that follows:
Figure 25: Edit Filter dialog
For example, when you select the New Filter item in the view Filter or Session Filter locations of the central Filter Expression Library, the Edit Filter dialog immediately displays and enables you to create and save a new Filter Expression. But when you select the Manage Filters item in either Library drop-down list, the Manage Filter dialog displays first; you can then create a new Filter Expression by right-clicking any of the built-in filter items in the Manage Filter dialog and selecting the Create a Copy command in the context menu that appears. Thereafter, the Edit Filter dialog displays from where you can modify the filter configuration, rename it, and save it back to the centralized Filter Expression Library as a new filter. Note that the Edit command is available for any Filter Expression that you right-click in the My Items category of the Manage Filter dialog, that is, if you want to modify one of your own custom-designed filters. Otherwise, you cannot edit any of the built-in Filter Expressions.
After configuring a new Session Filter, you can then select it during Live Trace Session or Data Retrieval Session configuration. You will also be able to select your new filter from the Library drop-down list on the Message Analyzer Filtering toolbar during an Analysis Session, but in this case, it will function as a view Filter only.
Note
Creating Filter Expressions from the Manage Filter dialog for a Live Trace Session is only one use of this feature, as the dialog has additional management features that are briefly described in the remainder of this section.
Centrally Managing Filters
The Library in which Session Filters are contained is a local, centralized Filter Expression Library that is populated by the Message Analyzer Filters asset collection, which is accessible from the Asset Manager dialog. You can manage the Filter Expressions from this collection in your user Library by using the Manage Filter dialog. Because Filter Expressions are contained in a single central Library, you can not only centrally manage the Library, but you can also use any Filter Expression that is contained in the central Library as a Session Filter when configuring a Live Trace Session or a Data Retrieval Session, or as a view Filter during a data Analysis Session. You can manage the Library from either the toolbar above the Session Filter text box of the New Session (or Edit Session) dialog, or from the Message Analyzer Filtering toolbar that appears in every Analysis Session. In both cases, you access the Manage Filter dialog by selecting the Manage Filters item from the Library drop-down list in these locations. The Manage Filter dialog is shown in the figure that follows:
Figure 26: Manage Filter dialog
Message Analyzer uses the same management dialog format to manage all user Library types; the only difference is the varying types of assets that you manage, for example Color Rules, Filters, Trace Scenarios, Viewpoints, viewer Layouts, Pattern Expressions, Chart Viewer Layouts, and so on. Therefore, in this Operating Guide, the management dialog is occasionally referred to generically as the Manage <AssetType> dialog. From the Manage <AssetType> dialog, you can import specific items; or export, delete, and modify selected items such as Filter Expressions; as described in Managing User Libraries.
Sharing Filter Items
The centralized Filter Expression Library items are shareable, as are items from other Message Analyzer asset collections. Message Analyzer provides a simple way to expose the Filter Expressions contained in this Library to others for sharing, or to retrieve Filter Expressions that others have shared.
To share Filter Expression items directly with others, you can use the Export feature in the Manage Filter dialog to save one or more Filter Expression items to a designated file share or other location. In addition, you can use the Import feature in the same dialog to access Filter Expression items that have been shared by others at a designated location. When exporting Filter Expressions, you have the option to select specific items that you want to distribute to others, including any items that you have created or modified. When importing a Filter Expression asset collection, you can choose the items you want to retrieve.
You can also share your Filter Expression items through a user-configured feed in the Message Analyzer Sharing Infrastructure. You can create such a feed from the Settings tab of the Message Analyzer Asset Manager (accessible from the global Message Analyzer Tools menu), by clicking the Add New Feed button and specifying a feed name and directory location. Thereafter, you can use the Export feature of the Manage Filter dialog to post your Filter Expression items as an asset collection to the configured feed location. You can also update an existing asset collection and make it available to team members or other users through your configured feed, where they can view, synchronize, and download the collection. However, for users to synchronize with collection updates, some manual configuration is necessary in the current Message Analyzer release, as described in Manual Item Update Synchronization. In future Message Analyzer releases, the Sharing Infrastructure publishing features may automatically enable others to synchronize with asset collection updates when they are shared through user feeds.
Accessing the Message Analyzer Filters Asset Collection
Microsoft provides a default Message Analyzer feed on the Downloads tab of the Asset Manager that enables you to download the Message Analyzer Filters asset collection once from a Microsoft web service and to synchronize with collection updates that are periodically pushed out by the service. To receive updates that will appear in the Message Analyzer category of the centralized Filter Expression Library, you must set the Message Analyzer Filters asset collection to the auto-sync state from the Downloads tab of the Message Analyzer Asset Manager, that is, if the collection is not already synced. At any time after setting the auto-sync state, you can perform a download of an auto-synced collection from the Settings tab of the Asset Manager. The Message Analyzer Filters asset collection is shown on the Downloads tab of the Asset Manager dialog in the figure that follows:
Figure 27: Asset Manager dialog
Note
If an automatic update to an auto-synced asset collection is pushed out by the web service to your Message Analyzer installation, the updates are automatically populated to your user Library, with no further action required.
