Overview

KPIs and datasets have a single value representation, which is part of the KPI and dataset definition. When a measure contains multiple data points, this representation is used to determine a single value for that measure. This representation is used by data rule-based notifications whenever the metric has more than one data point, and also by data controls that display a single metric value, such as a gauge, state indicator, or traffic light control.

Choosing a representation

The single value representation for a KPI or dataset is chosen in the General tab:

The General tab, where you define the single value representation.

The General tab, where you define the single value representation.


Caution: Before using any rules involving the first, last or (n)th data point, you should make sure you sort your data, or you may receive incorrect information.

Now that you have selected a single-value representation, any time the scheduler service samples any metric on this KPI or dataset, it will use the single value representation you have chosen. When defining a data rule-based notification, it is important to define the state in terms of the single value representation you have chosen.

At the KPI-level, the average of the last n data points is the same as the average of the last n records, for example.
