Intake format

A format defines the steps to extract and transform useful information from events into structured and normalized events and make them understable to decision-making-process.


Formats are grouped by module (a module usually correlates to a vendor).


A module contains:

  • meta-information in the _meta directory
  • as many sub-directories as there are formats

The _meta directory of a module hosts two files:

  • the logo of the vendor
  • a manifest.yml file with the UUID of the module, its name, a slug and a short description (cf AWS manifest)


A format corresponds to a product.

Each format will have the same tree structure:

The _meta directory consists of 4 files:

Definition of a parser

The parser is a set of instructions that schedules how information will be extracted from the raw event.

The parser is written in YAML format.

Refer to the How to write a parser documentation to develop your own parser.

Definition of smart descriptions

A smart description transforms a structured event into a readable description.

It may contain placeholders ({<fieldname>}) to display relevant information from the event (e.g. an IP address, a hostname, ….)

A smart description consists of:

  • The description with placeholders
  • A list of conditions when the smart description should be applied

    A condition is composed of a mandatory field name (property field) and a value (property value). With the presence of the value, the condition will test the content of the field against the value (like an equal operation).

    The absence of the value property will test the existence of the field in the event.

  • A list of relationships to link relevant information in the graph exploration

    A relationship relies on a source, a target and a word (type) to describe the relationship
