Splunk rex multiple values8/18/2023 ![]() ![]() The first Regex Function splits the event to separate the actual data from the header information. ![]() So we'll use two Regex Extract Functions. With this type of event structure, properly extracting each event field into a separate metadata field requires two-stage processing. ![]() This event is from a CheckPoint Firewall CMA system. Defaults to 100.įield name format expression: JavaScript expression to format field names when _NAME_n and _VALUE_n capturing groups are used. Named capturing groups will always use a value of 1. Max exec: The maximum number of times to apply the Regex to the source field when the global flag is set, or when using _NAME_N and _VALUE_N capturing groups. By the rex command we have matched the multiple in the same event and extracted the commands from each of the splunk queries in the Command field, which.

Usage įilter: Filter expression (JS) that selects data to feed through the Function. They are ephemeral: they can be used by any Function downstream, but will not be added to events, and will not exit the Pipeline. After that by the mvexpand we have made the Command field into a single-value field. Fields that start with _ (double underscore) are special in Cribl Stream. By the rex command we have matched the multiple in the same event and extracted the commands from each of the splunk queries in the Command field, which will be a multi-value field. (In Splunk, these will be index-time fields). The text string to search is: 'SG:G006 Consumer:CG-900004T01 Topic:ingressTopic Session: bc77465b-55fb-46bf-8ca1-571d1ce6d5c5 LatestOffset:1916164 EarliestOffset:0 CurrentOffset:1916163 MessagesToConsume:2'.
