Dashboard Pane (Indicators and Gauges)

You can display the most important parameters on a visual dashboard in a graphic form of widgets (indicators, gauges, and diagrams) so everybody could watch them. All widgets are displayed on the special pane called the dashboard. You can configure your system so the dashboard will be displayed on a separate big monitor. Every widget can only display one parameter. Widgets are created automatically so every check getting a numerical value is represented by a separate widget.

To display the dashboard pane, select a host on the map, display the context menu, and select Display indicators.

A separate window with widgets is created for each host. Widgets are only created for checks that have a monitored numeric parameter. Thus, the number of available widgets might not be equal to the number of available checks for a host. If you select several hosts, their widgets will be created on a single pane.

The program supports several types of widgets depending from the parameter type and specified measure units in a check. The widget type is usually selected automatically by the program upon the monitoring check creation (the program knows which parameter to display). But you can change the appearance of the indicator at any time in the check parameters (see the Disipaying units on charts topic).

The following types of widgets are available:

• Gauge

  

  It is used for displaying parameters changing from 0 to 100 per cent. For example, This can be the per cent of the CPU load.

  In order to display a parameter on a widget of this type, you need to specify the minimum and the maximum values for possible range of the parameter's values (see the Displaying units on charts topic). Set the min and max range values to 0 and 100.

• Circle diagram

  

  It is used for displaying only free or used disk space in various checks. Specify the minimum and the maximum values for possible range of the parameter's values (see the Displaying units on charts topic). Set the min and max range values to the minimum and maximum disk size.

• Bar diagram

  

  It is used for displaying only the bandwidth on network interfaces. Specify the minimum and the maximum values for possible range of the parameter's values (see the Displaying units on charts topic). Set the min and max range values to 0 and the total capacity value on this interface.

• Number indicator

  

  This universal indicator can be used for all other types of parameters which cannot be configured for using with the previous 3 types of widgets. This indicator does not require specifying the mix-max values of the parameter. But if you do this, the color of digits will change smoothly from blue to red going through green and yellow colors in the middle. This indicator perfectly suits for displaying temperatures. Specify the minimum and the maximum values of the temperature range and blue color will mean "cold" and red color - "overheating" (see the Displaying units on charts topic).

• Chart

  

  The program can display how a monitored parameter was changing in time with help of charts. The value axis is scaled automatically. This charts displays the data for the last hour.

If you want to display measure units on widgets, you will need to specify them in the Measure units field on the Check Parameters window (Step 2, the Units, min/max values, and Multiplier page). This window can also be displayed using the indicator's context menu.

If you want to see how the monitored parameter changed in time, you can display the chart window using the indicator's context menu (click the right mouse button on it).

The parameter caption under the widget can be specified in the check description on the Check Parameters window (Step 2, the Description page).

Widgets are refreshed once per second. Please keep in mind that the monitored values are racaived from the corresponding monitoring checks and they can have their own timing between updates according to the check interval (see the Check interval topic).

You can move and place widgets as you want on the pane. The grid is used to simplify the widget alignment.

You can add indicators of any checks to the panel. You can also create your own set of indicators and save it for using later.
