A config file for an application has the following three lines:Line 1: app build 1.

A horizontal discovery pattern is a series of operations that tell Discovery how to find and identify an application on a host1. To extract the build and version numbers from the config file, the pattern can use either of the following methods:

Parse File operation with Delimited Text parsing strategy: This operation reads the content of a file and splits it into fields based on a delimiter character. The pattern can specify the delimiter as a space and the fields to extract as the second and fourth ones from the first line of the file2.

Parse File operation with Regular Expression parsing strategy: This operation reads the content of a file and matches it against a regular expression. The pattern can specify the regular expression as app build (\d+\.\d+\.\d+\.\d+) version (\d+\.\d+) and the groups to extract as the first and second ones from the first line of the file2.
