Regex-expression Syntax: Description: The regular expression using the perl-compatible regular expressions (PCRE) format that defines the information to match and extract from the specified field. You must specify either or mode=sed when you use the rex command. Once you download the app below, you’ll get your report in just 30 minutes.Rex ( | mode=sed ) Required arguments Small, day-to-day optimizations of your environment can make all the difference in how you understand and use the data in your Splunk environment to manage all the work on your plate.Ĭue Atlas Assessment: a customized report to show you where your Splunk environment is excelling and opportunities for improvement. You don’t have to master Splunk by yourself in order to get the most value out of it. Try it out and see what issues you can solve. The spath command provides a great deal of flexibility when dealing with certain types of structured data onboarded as standard unstructured data. And, as we can see, the ordinates to coordinates | nomv coordinates | rex mode=sed field=coordinates "s/\n/,/g" We onboarded this data with a simple line breaker and not as indexed extractions. Here we see a dataset of meteorite impacts on the earth (shout out to jdorfman’s GitHub list of awesome JSON datasets – ). Data brought in as indexed extractions likely do not need spath, as the fields should already exist. Note: By event data, we mean the JSON that was not ingested as indexed extractions. How Spath Works on Compliant JSON Event Data: Here, we used spath and then a rename to pretty up the results (without the rename, we’d see team.NickName, team.City, etc.).įrom here, we now have a set of events and extracted fields to work with, and can then execute standard SPL to calculate statistics or create reports and dashboards. We could create regex and hope we know the field names or use spath to extract the fields quickly. So, we see an element named team, and additional elements one level under that. To help train our consultants, I created an XML that looks like this: Note: By event data, we mean the XML was not ingested as indexed extractions. How the spath Command Works on XML Ingested as Event Data Spath helps with specialty issues in JSON but shines with XML data. We’ll show that later on as we discuss scenarios in which spath or rename and multivalue commands make more sense. Splunk does well on JSON data, even if it’s brought in as event data. Distributed streaming can significantly enhance search performance with a robust set of indexers. Spath is a distributed streaming command, meaning that if it takes effect in our search before any transforming or centralized commands, the spath work will occur in the index layer. You can specify location paths or allow spath to run in its native form. The spath command extracts fields and their values from either XML or JSON data. How do you handle Splunk data and make it searchable? We could make regular expressions and hope the shape of the data is static-or we can use the easy button: spath command. Sure, you’d prefer to have brought it in as an indexed extraction, but other people onboarded the data before you got to it and you need to make our dashboards work. Your dilemma: You have XML or JSON data indexed in Splunk as standard event-type data.
