Portlets are the elements of any page within the Open Manage Network Manager web client. You can drag and drop them or add/delete them within pages to configure the portal’s appearance. Initially, they appear in a small, summary screen format. Click Add > More... to add a portlet to a page you have created. See Portlet Instances below for the distinction between portlets that display the same data, and portlets that can exist in more than one instance, displaying different data.

For a more specific look at available portlets, see the chapters following this one. The following describe common portlet features.

One of the first portlets typical users see is Discovery Profiles.

To act on listed items, right-click. A menu appropriate to the portlet appears.

The title bar for the portlet displays its name. To rename it, click on the name, and the field becomes editable. You can make changes, then click the green checkbox to accept them (or the red “X” to abandon them). The right portion of the title bar contains several editing controls. Clicking on the wrench icon produces a menu that leads to editors for the Configuration of this portlet (user permissions to view and configure, Sharing, and so on). 1

The plus or minus (+ or -) icons Minimize, displaying only the title bar, or Maximize, displaying an Expanded Portlets, and X removes the portlet from the page.

To see information about listed items in a portlet, hover your cursor over the row until a question mark appears. A mini-query about the selected item appears in a large tooltip. See Portlet Toolbar below for a description of the buttons at the top of portlets.

Portlet summary screens support displaying up to 200 rows, the expanded portlet supports 1000. Using the portlets’ filtering capability makes more sense than trying to see more rows. (See How to: Filter Expanded Portlet Displays.)

Portlet Toolbar

Buttons on portlet toolbars let you do the following:

? -- The Question Mark icon accesses online Help, opening the page appropriate for the portlet.

  Refresh -- Isolates the browser’s page refresh to the selected portlet

Settings -- Configures the portlet’s filter, size, and so on. In portlets like Alarms, this also can configure whether charts / graphs appear.

Even if the current filter is identical on summary and expanded portlets, the list of items may vary between the two views because they have different numeric limits for the number retrieved items. The workaround to make this difference irrelevant is to use the Search button to find items. It searches the entire database.

Search -- Locates an item in the portlet. When you click this, the columns filtered in the database appear indented. For example, Name and Model appear indented in the Managed Resource portal.

This search function highlights the column header in columns searched. This search provides a generic string search, and may not be compatible with all fields. For example you must use advanced search available in Expanded Portlets to search IP addresses.

Search appears in the footer if the widget has pagination.

Similar functionality is available in Expanded Portlets when you click these buttons in the upper right corner. The Settings button also lets you configure the columns displayed and their order. See How to Show / Hide / Reorder Columns.


The Settings button opens a screen where you can configure the Max Items that appear in, and the Filter applied to the summary portlet with an Apply button to activate any changes you make there. The Settings screen also includes a tab where you can Show / Hide / Reorder Columns.

For performance reasons, Max Items are often relatively low defaults.

Settings in expanded portlet does not include the Filter item where you can set the default filter for the portlet. See Filter Expanded Portlet Displays for information about the alternative.

As an Administrator, you can configure a portlet’s default display filter, then click the portlet name and re-name it. For example, make the default filter in Managed Resources display only Dell Routers, then click Managed Resources in the upper left corner of the portlet to rename it Dell Routers.

If you are not an administrator, you must make a personal page for such portlets if you want the filter settings to persist.


You can search by clicking Search at the top of portlets. This opens a search field where you can enter search terms for all the fields that appear in the list at the top of the portlet. The search is for what you enter, no wildcards are supported. To clear a search, clear the field.

This searches all available items in the database, whether they appear listed or not.

Sort on a column by clicking on that column’s heading. Reverse the sort order by clicking it again. This only sorts what appears in the portlet, whether expanded or not. The application remembers each user’s choice saving the last Sort Column and Order on any page. Most portlets also “remember” settings for Max Items and the selected Filter.

  1. Some portlets, like Site Map, let you import or export .lar files of their setup and user preferences.
