What is the default regular expression for LINE_BREAKER in Splunk?

The default regular expression for LINE_BREAKER in Splunk is designed to handle input data efficiently by recognizing what constitutes a line break. The regular expression operates on the principle that data sources may contain varying types of line breaks, including both new lines and carriage returns. This approach allows Splunk to accurately segment log entries or other textual data into individual events during the indexing process.

By using a regular expression that matches any sequence of new lines and carriage returns, Splunk is equipped to handle diverse data formats that may not adhere to a single standard. This flexibility is vital for processing logs from different operating systems and applications, which may use different conventions for line breaks. Consequently, this default setting enhances the ingestion process by minimizing the need for additional configuration adjustments from the user, ensuring that data is captured and indexed in a structured manner.

This reliable and adaptive line-breaking strategy is essential for maintaining data integrity and improving the overall effectiveness of searches and queries within Splunk.
