The CASE () and TERM () directives are similar to the PREFIX () directive used with the tstats command because they match. Wherever the regex matches, Splunk considers the start of the first matching group to be the end of the previous event, and considers the end of the first matching group to be the start of the next event. – Splunk uses over 30 different REGEX patterns to search the event for a suitable timestamp that it can use. How handles your data. Pages 310 This preview shows page 297 - 299 out of 310 pages. Event segmentation breaks events up into searchable segments at index time, and again at search time. While Splunk software has indexed all of the fields correctly, this anomaly occurs because of a configuration setting for how Splunk software extracts the fields at search time. Then, it calculates the standard deviation and variance of that count per warns. If it is already known, this is the fastest way to search for it. Summary.
