Condition for forwarding data to an extra normalizer

The Add normalizer to normalization scheme window is used to specify the conditions under which the data will be sent to an extra normalizer.

Available settings:

• Fields to pass into normalizer—used to indicate event fields in case you want to send only events with specific fields to the extra normalizer. Leave the field empty if you want to send all data to the extra normalizer.
• Use normalizer for events with specific event field values—used to indicate event fields if you want the extra normalizer to receive only events in which specific values are assigned to certain fields. The value is specified in the Condition value field.

  The data processed by these conditions can be preconverted by clicking the button. This opens the Conversion window, in which you can use the Add conversion button to create rules for modifying the original data before it is written to the KUMA event fields.

  Available conversions

  Conversions are changes that can be applied to a value before it gets written to the event field. The conversion type is selected from a drop-down list.

  Available conversions:

  • lower—is used to make all characters of the value lowercase
  • upper—is used to make all characters of the value uppercase
  • regexp—is used to apply a RE2 regular expression to the value. When this conversion type is selected, the field appears where regular expression should be added.
  • substring—is used to delete characters in the position range specified in the Start and the End fields. These fields appear when this conversion type is selected.
  • replace—is used to replace specified character sequence with the other character sequence. When this type of conversion is selected, new fields appear:
    • Replace chars—in this field you can specify the character sequence that should be replaced.
    • With chars—in this field you can specify the characters sequence should be used instead of replaced characters.
  • trim is used to remove the characters specified in the Chars field from trailing positions of the value. The field appears when this type of conversion is selected.
  • append is used to add the characters specified in the Constant field to the end of the event field value. The field appears when this type of conversion is selected.
  • prepend—used to prepend the characters specified in the Constant field to the start of the event field value. The field appears when this type of conversion is selected.
  • replace with regexp—is used to replace RE2 regular expression results with the character sequence.
    • Expression—in this field you can specify the regular expression which results that should be replaced.
    • With chars—in this field you can specify the characters sequence should be used instead of replaced characters.
