Why am I not getting any results trying to get a count by field?

[guillecasco]

Pretty new with Splunk, simple question.

I have:

index=*  asset id: "*"  

I just want a table that counts every different asset id and show them in a table like:

assetid   count
abc       50
dfg       25
....      ....

using the count by, but I'm not getting any results.

You need to extract asset id values into a field assetid, After which you can add | stats count by assetid at the end of your search to produce the resultset you wanted.

Use the built in field extractor if you need help in extracting the values into a field
