Dashboard Views

The Dashboard Views portlet lets you assemble several monitors into a single display, or dashboard. You can create and display dashboards by right-clicking items in Managed Resources, selecting Show Performance, or by selecting New in the Dashboard Views portlet.

Right-click the listed dashboards, and a menu appears that lets you Rename, Delete, Edit, create a New simple or custom dashboard, or Launch a Dashboard View (either Maximize--a larger view--or as a Popup). See Dashboard Editor for information about creating or modifying dashboards. For an explanation of Convert, see Convert Simple Dashboards to Custom Dashboards.

The Performance Dashboard and Dashboard Editor describe configuring simple dashboards. See the How to: Create a Custom Dashboard View section for a description of custom dashboard view creation.

You can also Convert Simple Dashboards to Custom Dashboards, as described below. When you Edit a view, Dashboard Editor appears. It lets you select which monitors appear in the dashboard, the monitored entities, and attributes.

The expanded portlet offers similar capabilities. To make a monitor appear on a page, use the portlet described in Performance Dashboard.

When you create dashboards, data rollup is part of what the display shows. If, for example, the monitor displays the results from a boolean (0 or 1 output), rollup may average values for a duration, and values less than one will appear in the graph.

Launch a Dashboard View

Launching a view lets you view the monitors active for a Dashboard view.

Some packages display a Network Dashboard by default. If the Network Dashboard portlet is blank, you can create a dashboard, then click the select new text in the upper right corner of the portlet to select an alternative, already configured view from those in Dashboard Views portlet. Click the edit button in that same corner to alter the configuration of any existing dashboard. See Dashboard Editor for more about altering views.

You can configure Dashboards appear by configuring them in the Dashboard Views portlet, or by selecting a device or devices in Managed Resources portlet, right-clicking and choosing Show Performance. To select more than one device, use the expanded Managed Resources portlet.

The first time you create a default template dashboard for a single device, Open Manage Network Manager saves it in the Dashboard Views manager. Invoking Show Performance for that device subsequently displays its default view.

The icons in the dashboard’s upper right corner let you edit Dashboard Properties with the Dashboard Editor, or Save the dashboard with the other icon.

Displaying Values

Hovering the cursor over the individual points displays the charted attribute value(s) as popup tooltips. If a graph has multiple lines, the data points for different lines are charted at different times (Open Manage Network Manager distributes polling to balance the load on its mediation service). Hover the cursor over the time when a line’s data point appears, and that line’s value appears as a tooltip. It may seem a device reporting the same value as others is not graphed properly, but mousing over the graph displays the value.

The legend of devices and/or attributes that appear in each graph also provides interactive features. Hover your cursor over a device or attribute color in the legend and only that device or attribute appears onscreen. By default all such legend color squares contain checks. Uncheck the ones you do not want to see. The legend can appear consolidated or for each chart, as is appropriate to the distribution of charted devices and attributes.

If no data is available for an attribute in a dashboard, no panel appears for that data.

Changing Dashboard Time / Date Format

Control panel’s Redcell > Application Settings screen has a Performance Chart Settings panel where you can set the Day Format and Minute Format so dashboards display time (the x axis) in a meaningful way. If you want european date formats (day/month/year rather than month/day/year), this is available if the language / location settings of the operating system on the computer running Open Manage Network Manager makes it available.

In Control Panel’s Performance Chart Settings panel, you can also enable Threshold display in dashboards and elect to Restrict Y-Axis Range to data range with checkboxes.

Create a Simple Dashboard View

Follow these steps to create a simple dashboard view. See How to: Create a Custom Dashboard View for more complex monitor creation.

1. In the Dashboard Views portlet, right click to select New > Simple Dashboard.

2. Select a name (for example SNMP Interface, to display the monitor configured in How to:Create an SNMP Interface Monitor).

3. Click Add Entity in the Entities panel.

4. In the filter that appears, select the type: Interface.

5. Filter for the IP address of the entity monitored in the previous SNMP interface monitor creation, select it and click Add Selection and Done.

6. Select the ifInErrors attribute, and click the right arrow in the Dashboard View Attributes panel.

7. Click Save. The dashboard view you have configured should appear in the portlet.

8. To launch it, right-click and either Launch (Popup) or Launch (Maximize)

9. If you want to convert this simple dashboard to a custom dashboard so you can alter it further, right-click and click Convert.

10. Notice that you can also change the time/date format as described in Changing Dashboard Time / Date Format above.

To improve performance, SNMP Interface Monitor does not retain polled data by default. You cannot use historical attribute data in a dashboard without this retention.
