Working With Data Views

Application Discovery can automatically refresh data to the interface screens at variable intervals. You can select the interval you prefer, or you can turn the refresh interval off. The default refresh interval is 20 minutes.

To change the refresh interval, use the "Refresh interval" drop-down to select the setting that you prefer.

Your selection is applied automatically and immediately.

	Screen Refresh When Clicking Tabs or Links: Screens with long lists of systems, applications, or packages take more time to refresh. If a screen appears to be empty when you first click to it, please wait a few seconds for the refresh to complete.

First and foremost, visibility of systems and applications depends on the permissions a user has for each managed system and application. Users can see only those systems and applications in Application Discovery tables that they already have permission to access or view.

That said, for those applications for which you have permission to view, you can further alter application visibility by changing this configuration.

Use the "Application visibility" drop-down to affect visibility of applications across your network.

Your selection is applied automatically and immediately on all data tables in Application Discovery.

Another way to do this is to use the drop-down selector the appears above tables that list applications. The following figure shows these visibility selectors. The visibility setting selected here is also applied to all application tables in Application Discovery screens.

Your selection is applied automatically and immediately to the Application Discovery user interface.

To help you to view manageable chunks of data, you can select the maximum number of rows to display within an Application Discovery table. Application Discovery apportions the data into separate pages based on the number that you select.

Use the "Table bucket size" drop-down to select the number of rows that you want to appear in each table per page. The default number of rows is set to 50, but you can select more or fewer rows for each table page. (See Figure 3-1.)

Your selection is applied automatically and immediately to all data tables in Application Discovery.

The default sort order.   Each table displays with one column having a dark grey background in the column heading and an arrow. The dark grey color indicates which column is driving the sort order for all rows of data in the table. The arrow indicates whether the column has been sorted in ascending or descending order. Criteria for the order may be numeric or alphabetical.

Figure 3-3 Sort Indicator

Changing the sort column.   To change which column is driving the sort order for the table, click on or near the title of the column containing the criteria by which you want to sort. The background color of the newly selected column heading changes from medium grey to dark grey, revealing the sort arrow indicator.

Changing the sort order.   Click the arrow in the selected column to toggle between ascending and descending order.

The default filter  The initial filter state of a table is set to 'none' so that all known data for that table view is displayed.

Hiding specific rows by a selected criteria.   You can hide specific rows of data by right-clicking on any text in a table row, and choosing to filter in or filter out a piece of data. For example, you may want to hide all rows containing server_name_y. To do so, right-click on server_name_y in any table cell containing that server name, and select Filter out server_name_y. All rows containing that name are no longer be visible in the table when the view refreshes.

Showing hidden rows.   To return the table to its original default state (thereby revealing all rows hidden up to this point), right-click on any table row and select Clear filter. The table returns to its original state.

	NOTE: Hidden applications.  Note that the filtering discussed in this section concerns manipulating data that is currently displayed in the tables. Some applications are not shown in the table. They might be common, low-level processes that are hidden by default, or they might have been hidden by a user. To quickly see how many applications might be hidden from view, look at the upper right hand corner of the application table, as shown in the following figure. Figure 3-4 Section of Application Table Showing the Count of Hidden Applications

Refresh the page data.   Right-click anywhere in the view screen and select Refresh page.

Collapse a table.   Right-click on any table row and select Collapse table to remove the rows of data from view. This function is most useful when multiple tables are present on a screen and you want to quickly move to other tables.

Expand a table.   Within a collapsed table, right-click anywhere in the table title bar and select Expand table to expose the data for that table.

	NOTE: On screens with multiple tables, the tables have an expand/collapse icon ( or ) in the upper left corner of the table title bar. Click the icon to expand or collapse the table.

Application Discovery provides two navigation aids to help you move from data view to data view.

To help you control the amount of data presented to you, Application Discovery provides several ways to modify the visibility of objects in Application Discovery screens. In addition to modifying host visibility (discussed here) you can also change the visibility of packages and applications.

To change visibility of a matched application:

	NOTE: When creating a workload in HP Virtualization Manager, you have the option of checking 'Show All Running Applications'. In essence, this check box allows you to reveal all running applications that have been previously marked as hidden in HP Application Discovery by a user or by default. See “Add Selection by Application” in HP Virtualization Manager Help for usage instructions.

Memory use might be higher during the initial warmup period when application discovery is at its height, and lessening over time as the majority of discovery is completed.
