How do I group similar values in fields throughout all events together?

From a human standpoint, we realize that there are effectively two groups of data here in the "Serial" field. One starting with "1", and one starting with "9":

  • Serial=123456789
  • Serial=123456788
  • Serial=123456787
  • Serial=987654321
  • Serial=987654322
  • Serial=987654323

How do I leverage Splunk to spit out all of the values in the groups we know exist, organized together and displayed in front of me? I have over 6,000 unique "Serial" values probably making around 15 "groups", but I can't figure out how to get the data organized how I want.

I thought cluster command would work but it doesn't seem to display every unique value in the group, only the top hitter. Correct me if I'm wrong.

  • index=stuff Serial="*" | cluster t=0.35 field=Serial | stats values(Serial) by cluster_label

Any ideas welcome.

How about this

index=stuff Serial="*" | stats count by Serial | eval Group=substr(Serial,1,5) | stats values(Serial) by Group

The rhyme or reason as to why serial is created with certain patterns is unknown to us, but we want to figure it out. We are working backwards here.

So the problem is that is impossible, and why I want to use the cluster command if possible. I need fancy math to relate things together for me.

You would have to define the pattern using which you can group Serials. Based on your fixed pattern you change the query.

Ah thank you. I realize I left out a crucial part of the data set the makes a specific grouping impossible though. This is a more realistic set:

  • Serial=102312-6789
  • Serial=102315-6389
  • Serial=102322-6787
  • Serial=028765-4321
  • Serial=328765-4331
  • Serial=918765-4391
