![]() The first Regex Function splits the event to separate the actual data from the header information. ![]() So we'll use two Regex Extract Functions. Looking at the fictional source type implsplunkweb, we see results that look like. With this type of event structure, properly extracting each event field into a separate metadata field requires two-stage processing. We can accomplish this with rex, or if needed, multiple rex statements. 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. I can do multiple group and multiple values, but not ONE group with many values. but a simple question actually, how can i have one group and multiple values. Source field: Field on which to perform regex field extraction. 1 Why are you trying to use regex to parse XML madreflection at 16:40 just trying to do field extract, I am currently working on nf. See Examples below.Īdditional regex: Click Add Regex to chain extra regex conditions. I am working with events that look like this. Can contain special _NAME_N and _VALUE_N capturing groups, which extract both the name and value of a field, e.g.: (?+)=(?+). Splunk : extract multiple values from each event Ask Question Asked 12 months ago Modified 12 months ago Viewed 1k times 0 I am new to Splunk queries and I am not able to figure out how to extract multiple values from same event. Must contain named capturing groups, e.g.: (?bar). Defaults to empty.įinal: If toggled to Yes, stops feeding data to the downstream Functions. Defaults to true, meaning it evaluates all events.ĭescription: Simple description of the Function. 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. Virtually all searches in Splunk uses fields. Fields that start with _ (double underscore) are special in Cribl Stream. What is a field A field is a name-value pair that is searchable. (In Splunk, these will be index-time fields). The Regex Extract Function extracts fields using regex named groups.
