Whether your business measures success based on the current value of a single metric, the aggregate value of metrics across devices, a value from your database, or a combination of any of the above, you can represent it in an at-a-glance view with the Big Number widget.
Creating a Big Number widget is a multi-step process. First, select the datapoints you wish to include. These can be values of a datapoint on a single instance or values of datapoints across instances.
Once your datapoints have been added, you can create virtual datapoints if desired. This gives you the ability to change units of measure, combine values, or perform a function on the value prior to display. You can also add two values together to create a single value, although ensuring the values are in the same unit of measure is recommended.
The final step is to select which values will appear as numbers in the Big Number widget.
Click on the Add drop-down and select Big Number widget from the list. The Configuration form for setting up the widget will be displayed. See these instructions for help filling out the title, description, dashboard and refresh frequency fields.
Begin adding datapoints and virtual datapoints by following our instructions for configuring datapoints to be displayed in your widget. Additional configuration items for each datapoint include Name and Aggregate function:
Provide a name for this datapoint configuration.
This field displays only for real datapoints that have been set to monitor more than one individual instance. It allows you to choose the max, min, or sum of the values from the multiple instances.
When configuring the Big Number widget, you first need to select the datapoints which will be represented in the widget. The following configuration will give you the value of the CPUutilization datapoint for an AWS EC2 instance :
Once you have configured the individual datapoints, you will be able to configure the “Numbers” section, which determines how the datapoints will be displayed:
Assign where the value should display in the widget. In the example Big Number widget displayed below, you can see that position 1 displays in the upper lefthand quadrant, position 2 in the upper righthand quadrant, position 3 in the lower lefthand quadrant, and position 4 in the lower righthand quadrant.
Enter text to clarify the unit of measure for the number displayed.
Enter the text you would like to see as the bottom label for the value.
Select the data point whose value you want to display on each number section. You will be able to choose from all the data point and virtual data points you configured under Big Number Datapoint Options. Additionally, selecting the “Device Count” datapoint will return the number of devices that match any AppliesTo expression.
Round to the nearest whole number, tenth (one decimal place) or hundredth. For values with more decimal places, a virtual datapoint is recommended.
Toggling this option on will allow you to change the color of a datapoint’s dedicated quadrant to yellow, orange or red as soon as it meets the criteria of a specified alert threshold. This is an excellent way to provide an at-a-glance warning about the status of your metrics’ values.
