Meter Configuration

When you double-click the Meter processor function, the function’s configuration dialog opens.

In the Meter key field above the settings in the Configuration tab, an automatically created Meter key will be displayed. This key is one of the parameters used when creating meters using the APIs, see API Documentation, and next to the field is a Copy button that you can use to copy the key when creating meters.

The Configuration tab contains the following settings:

Guiding rules
