![]() ![]() Use the rex command for search-time field extraction or string replacement and character substitution. Running the rex command against the _raw field might have a performance impact. If a field is not specified, the regular expression or sed expression is applied to the _raw field. This sed-syntax is also used to mask sensitive data at index-time. When mode=sed, the given sed expression used to replace or substitute characters is applied to the value of the chosen field. ![]() The rex command matches the value of the specified field against the unanchored regular expression and extracts the named groups into fields of the corresponding names. Splunk uses the rex command to perform Search-Time substitutions. Does the run-anywhere search above work on your Splunk If it doesnt, then you have something seriously odd going on. As you can see, there is only one correlationid the value 11315ad3-02a3-419d-a656-85972e07a1a5 is nowhere in this sample.

I have come up with this regular expression from the automated regex generator in splunk: n s+. If this is not exactly correct for your logs, it should at least get you very close. Use the stats command with count by to count the current results, binning by your new 'methodName' field. Use the where command to filter the results to where your new 'duration' field > 10ms. Use to either extract fields using regular expression named groups, or replace or substitute characters in a field using sed expressions. The text I want to extract is everything between reason and appName, which is. I am trying to create a regular expression to only match the word Intel, regardless of the relative position of the string in order to create a field.
