Modifiers

Modifier is module which performs particular modification on data before collection happens.

Each modifier consists of two elements:

• module name,
• parameters.

Module name

This name is unique identifier for each modifier (and each module in collect phase).

Parameters

This is set of key-value pairs using which user can pass some configuration and information to modifier. Parameters for modifiers can be divided into two groups:

• mandatory - parameters without which modification will not be possible,
• optional - passing this parameter is not obligatory, usually they trigger some functionality extensions.
