A horizontal discovery pattern is a sequence of operations that collects information about a specific type of configuration item (CI), such as an operating system, a database, or a web server1. A horizontal discovery pattern does not use the connectivity section, which is only used for the application pattern type2. The connectivity section defines how to connect to a CI and run commands on it3. A horizontal discovery pattern uses the following sections1:
* Variables: Defines the variables that store the data collected by the pattern and map them to the target table fields.
* Identification: Defines the criteria to identify a CI and update or create a record in the CMDB.
* Operations: Defines the actions to perform on the target CI, such as running commands, querying databases, or parsing files.
