Parsing multiline logs using a custom Fluent Bit configuration

Fluent Bit can be used to improve the readability of multiline logs by consolidating them into a single log record. This can make it easier to understand and analyze logs, especially when dealing with complex or nested log messages. A custom Fluent Bit configuration can be created using a configurable multiline parser to identify the start and continuation lines of a multiline log message. The configuration uses regular expressions (regex) to match the start state and potential continuation lines, allowing for more accurate parsing and consolidation of multiline logs. With this configuration, multiline logs can be consolidated into a single log record in New Relic, making it easier to read and analyze them.
