Datamodel=File_or_Folder_Modification calling important files.ģ.Another data model to verify process id or other file values modificationĤ.Lookup related commands to attempt whitelisting. Result seeing in job inspector: (process_name='C://Program Files//Computer//)ġ. Result: (process_name='C:/Program Files/Computer/)īut whenever I implement this portion of the search to the rest of the search to verify actual real results it adds again the double back lash.

| rename whitelisted_process_name as process_name If I run this specific portion of the search by itself it looks appropriately without adding the double back slash We have identified this search produces several False Positive from regular business activities so we were trying to whitelist those using a lookup that contains some relevant fields to later be exclude/whitelist. What I can tell you is that the search uses a couple of data models to first provide information such as process name and object name, then identifies several files or folder modification. Unfortunately, I cannot share the whole search since due to security reasons. So kindly help me with the regex for the same.Hi I have a SPL that detects several files modification within short time as part as possible ransomware infection.

Output should be as below for Forwarder Field name as: Consider the 3rd (vvv.vv.vvv.vvv,+vv.vvv.v.vvv,+vv.) & 4th output (vvvv:vvvv:vvvv:vvvv:vvvv:vvvv:vvvv:vvvv,+) in which the 'Forwarder' field has multiple IP's in the same field for the 3rd and 4th output so we want to extract in separate fields under 'Forwarder' with each IP.ġ23.456.78.912,+45.675.3.123,+32.123.456.55 By default, the internal fields raw and time are included in output in Splunk Web. So I want to split them up in the same field name 'Forwarder' i.e. Keeps or removes fields from search results based on the field list criteria. For a discussion of regular expression syntax and usage, see an online resource such as or a manual on the subject. Vvvv:vvvv:vvvv:vvvv:vvvv:vvvv:vvvv:vvvv,+ This primer helps you create valid regular expressions. 07:32:20 xx. GET / - 443 - xx.xxx.x.xx - x xx x x - The rex command performs field extractions using named groups in Perl regular expressions. 01:14:47 xx.

I would like to join the result from 2 different indexes on a field named OrderId (see details below) and show field values from both indexes in a tabular form. 06:23:17 xx.

The reason I want all of this together is because. AAABBB' Client'112233',source'aassdd' server'IIHHSS. And the current output is as below from all the 5sample events and for the 5th sample event we don't have the 'vvv' value itself in the logs. The text I want to extract is everything between reason and appName, which is. So already we have a field extraction in place i.e. I have sample set of events coming from the same logs and here 'x' denotes a digit mostly IP address in this case and my requirement is that to splitthe data in the existing field 'Forwarder' which is mentioned as 'v'.

Splunk rex multiple fields
