Filtering fields

User the Filter tab, you can restrict which messages a subscriber receives based on the content of both the header and body of the message.

Only those messages that conform to the filter specified are validated or stored. Messages that do not conform are ignored.

For scalar fields, the same action types that are available for validation can be used for filtering. See Validating scalar fields.

For message-based fields, more types are available, as follows:
  • Does Exist can be used to accept or ignore messages that are based on whether the selected field actually exists in the message.
  • Name and Type can be used to accept or ignore messages that are based on the name or type of the message field.
  • Is Null, Not Null, and Assert using Function are also available.
For more information, see Validating scalar fields.
