Values polled by a custom poller are often better understood after a calculation transforms the value to a different format. For example, if a poller returns values in MB, you might want to work with the values presented in GB. The calculations and transformations that are used to manipulate poller results are called formulas.

Two types of values or data sources are available:

  • Scalar: one value
  • Tabular: column of values

When a new data source is created, the name is generated automatically according to the syntax:

<Property name>Formula<Number>

For example: UsedMemoryFormula1
