I got couple of log entries like below

I want to create a recipient multivalue field which will be containg email addresses

Give this a spin:

index=_internal source="/opt/splunk/var/log/splunk/python.log"
| rex max_match=0 field=recipients "u'(?<recipient_list>[^']+)"
| stats values(recipient_list) as Recipients count by subject
| sort - count
| addtotals col=t row=f

I'm on Splunk 6.x, so my recipients field looks like this:

recipients="[u'[email protected]', u'[email protected]', u'[email protected]']",

If you are on 6.x then my search should work perfectly for you. But if you are on an older version of Splunk, you may have a different log format. For the example you showed us above, there is no u in front of the single-quoted recipient's email address. If that is still the case, just remove the u so the rex line looks like this:

| rex max_match=0 field=recipients "'(?<recipient_list>[^']+)"

Be sure to vote this up if it works for you! 🙂

Oh, and the max_match=0 makes the number of matches unlimited, so it recurses, creating a multivalued field called recipient_list. max_match has the default setting of 1 unless you change it.

Something like this:

  * | head 1 | eval recipients="['[email protected]','[email protected]','[email protected]']" | rex field=recipients "(?<data>[a-z\.@\,\s']+)" | makemv delim="," data

I do proper field extraction in my props.
