Splunk Search

Compare 2 fields

mcafeesecure
Explorer

Basically I have a line of data that looks like this:

Jun 28 14:15:10 sc4-app04.mcafeesecure.com portal: ACCESS Click Referrer[bluecigs.com][http://www.blucigs.com/privacy-policy]

I have rex set up to extract two parts of this:

rex "(?i) Referrer\\[(?P<REF1>[^\\]]*)(?=\\])" | rex "(?i)www\.(?P<REF2>[^/]*)(?=/)" 

This will basically give me 2 fields I can search on REF1 and REF2.

I would like only messages that do NOT have those two fields matching to show up for instance, in the previous entry I get

REF1=bluecigs.com
REF2=bluecigs.com

the following line I would have them NOT matching:

Jun 28 14:15:10 sc4-app04.mcafeesecure.com portal: ACCESS Click Referrer[bluecigs.com][http://www.SOMEOTHERDOMAIN.com/]

IE: REF1=bluecigs.com
REF2=SOMEOTHERDOMAIN.com

Is there a way to compare the fields?

You can do this by using the where command:

<your search> | where REF1!=REF2

I would imagine you could add this to the end of your search

| search NOT REF1=REF2

but that may also give you events where REF1 and REF2 don't exist.

Try it out and let us know!

This won't work. It would compare the value of the field REF1 with the value "REF2" (ie. not the value of field REF2).
