Splunk Search

comparing data from index and input table

New Member

Hi Everyone,

Thanks for your support too.

I have indexed data of staff events from a source. One field in that data is "Surname".

I have an input table of all staff, field 1 is "Surname".

Please can you help me to report on all staff names from the input CSV that do not have events in the indexed data?

Thank you so much!

Something like this might help.

(your indexed search that returns Surname)
| stats count AS SurnameCount by Surname
| inputlookup staff_lookup.csv append=true
| chart sum(surnameCount) as abc by Surname
| eval abc=if(isnotnull(abc),abc,0)
| where abc=0

This uses a sentinel value concept, better explained here: https://conf.splunk.com/session/2015/conf2015-LookupTalk.pdf on slide 25
