Regex - Search for Number Range within Array/String

chburnett — Sat, 02 Jan 2016 06:25:42 GMT

Sample Data:

ID | [[Event1,1435],[Event2,78],[Event3,142]] | etc.....

I'm wanting to build a query which will display the ID and the entire field of event data where 'Event2' is greater than (x).

I'm not overly familiar with regular expressions, so if anyone can point me in the right direction, I'd greatly appreciate it. As it, I'm searching for ([Event2,1] OR [Event2,2] OR [Event2,3] . . .)

I'm trying to optimize my search here, and have had one heck of a time trying to self-instruct myself regex.

Hi,

Not sure if this is what you want:

yoursearch
| rex field=_raw "(?<id>\d+) \| (?<events_raw>[^\|]+) \|"
| rex field=events_raw max_match=0 "\,(?<events>\d+)\]"
| eval MyEvent=mvindex(events,1)
| where MyEvent > 50
| table id, events

The regex above will extract all your events as a multifield and then you can use the mv commands to filter when Event X is greater than any given value.

Hope that helps.

Thanks,
J

Hi,

Try with this:
| rex "Event1,(?P[0-9]+).*Event2,(?P[0-9]+).*Event3,(?P[0-9]+)" | search Event2 >

Besides, you should have a look on the Splunk built-in field extractor documentation. This feature allows you to simply extract fields thru the GUI, without any particular knowledge of regex. And here is a website to learn regex: http://regexone.com/lesson
