Note the green indicator in the Server State description in the above image. This indicates that the server sourcing the information is functioning normally. A yellow indicator indicates that server operation is less than optimum. A red indicator indicates that the server is down. These indicators are the same as for the server health on the Manage Servers page in the regular web UI.

Graphed lines and stacked areas in the charts follow a standard color and visual coding so that you can immediately determine key diagnostic indicators at a glance. The charts use the following color and textural indicators:

• High alerts or warnings —Lines or areas in red, with a hatched texture.
• All other indicators —Lines or areas in various other colors distinguish the data elements. The charts do not use green or yellow.

You can magnify a chart in a separate window by clicking the Chart Link icon at the bottom of the panel chart and then by clicking the Magnified Chart option (see the image below). In magnified chart view, you can choose an alternative chart type from the one that comes up initially (see Other Chart Types).

Note	Automatic refresh is turned off for magnified charts. To get the most recent data, click the Refresh icon next to the word Dashboard at the top left of the page.

To convert a chart to a table, see the Displaying Charts as Tables section. You cannot convert tables to a graphic chart format.

Each chart includes a color-coded legend by default.

Dashboard elements rendered as tables have data displayed in rows and columns. The following dashboard elements are preset to consist of (or include) tables:

• DHCP DNS Updates

• DHCP Address Current Utilization

• DHCP General Indicators

• DNS General Indicators

• Caching DNS General Indicators

Note	If you view a table in Expert mode, additional data might appear.

Dashboard elements rendered as line charts can include one or more lines plotted against the x and y axes. The three types of line charts are described in the following table.

Tip	To get the raw data for a chart that shows delta or rate data, enter Expert mode, go to the required chart, click the Chart Link icon at the bottom of the panel chart, and then click Data Table . The Raw Data table is below the Chart Data table.

Dashboard elements rendered as area charts have multiple related metrics plotted as trend charts, but stacked one on top of the other, so that the highest point represents a cumulative value. The values are independently shaded in contrasting colors. (See the image below for an example of the DHCP Server Request Activity chart shown in Line Chart Example rendered as an area chart.)

They are stacked in the order listed in the legend, the left-most legend item at the bottom of the stack and the right-most legend item at the top of the stack. The dashboard elements that are pre-set to area chart are:

• DHCP Buffer Capacity

• DHCP Failover Status

• DHCP Response Latency

• DHCP Server Leases Per Second

• DHCP Server Request Activity

• DHCP Server Response Activity

• DNS Inbound Zone Transfers

• DNS Network Errors

• DNS Outbound Zone Transfers

• DNS Queries Per Second

• DNS Related Server Errors

The other chart types available for you to choose are:

• Line —One of the line charts described in Line Charts.

• Area —Charts described in the Area Charts.

• Column —Displays vertical bars going across the chart horizontally, with the values axis being displayed on the left side of the chart.

• Scatter —A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.

Tip	Each chart type shows the data in distinct ways and in different interpretations. You can decide which type best suits your needs.

You can open a help window for each dashboard element by clicking the help icon on the table/chart window.

Refresh each display so that it picks up the most recent polling by clicking the Refresh icon.

You can set how often to poll for data. Click the Dashboard Settings icon in the upper-right corner of the dashboard display. There are four options to set the polling interval of the cached data, which polls the protocol servers for updates (See the image below).

You can set the cached data polling (hence, automatic refresh) interval to:

• Disabled—Does not poll, therefore does not automatically refresh the data.

• Slow—Refreshes the data every 30 seconds.

• Medium—Refreshes the data every 20 seconds.

• Fast (the preset value)—Refreshes the data every 10 seconds.

Use the Chart Link icon at the bottom of the panel chart to view the chart link options (see the image below). You can choose to display a graphic chart as a table by clicking the Data Table option.

You can dump the chart data to a comma-separated value (CSV) file (such as a spreadsheet). In the Chart Link controls at the bottom of the panel charts (see the above image), click the CSV Export option. A Save As window appears, where you can specify the name and location of the CSV file.

You can set the default chart types on the main dashboard view. You can customize the server charts in the dashboard to display only the specific chart types as default.

To set up default chart type, check the check box corresponding to the Metrics chart that you want to display and choose a chart type from the Type drop-down list. The default chart types are consistent and shared across different user sessions (see the image below).

Note	You can see either the CDNS or DNS Metrics in the Dashboard Settings > Chart Selection page based on the service configured on the server.

Tip

The order in which the dashboard elements appear in the Chart Selection list does not necessarily determine the order in which the elements will appear on the page. An algorithm that considers the available space determines the order and size in a grid layout. The layout might be different each time you submit the dashboard element selections. To change selections, check the check box next to the dashboard element that you want to display.

The above image displays the Charts Selection table in the regional web UI. The Clusters column is available only in regional dashboard and it displays the list of local clusters configured. You can add the local cluster by clicking the Edit icon and then by selecting the local cluster name from the Local Cluster List dialog box.

To change selections, check the check box next to the dashboard element that you want to display.

Specific group controls are available in the Change Chart Selection drop-down list, at the top of the page (see the image above). To:

• Uncheck all check boxes, choose None .

• Revert to the preset selections, choose Default . The preset dashboard elements for administrator roles supporting DHCP and DNS are:

  • Host Metrics: System Metrics

  • DHCP Metrics: General Indicators

  • DNS Metrics: General Indicators

• Select the DHCP metrics only, choose DHCP (see the "DHCP Metrics" section in Cisco Prime Network Registrar 11.2 DHCP User Guide).

• Select the DNS metrics only, choose DNS (see the "Authoritative DNS Metrics" section in Cisco Prime Network Registrar 11.2 Authoritative and Caching DNS User Guide).

• Select the DNS metrics only, choose CDNS (see the "Caching DNS Metrics" section in Cisco Prime Network Registrar 11.2 Authoritative and Caching DNS User Guide)

• Select all the dashboard elements, choose All .

Click OK at the bottom of the page to save your choices, or Cancel to cancel the changes.

You can change the chart type by clicking the Chart Type icon at the bottom of the panel chart and then by selecting the required chart type (see the image below). The different types of chart available are: Line Chart, Column Chart, Area Chart, and Scatter Chart.
