Splunk Search

Return NOT matching events

munisb
Explorer

Hi,

I am trying to return values that DO NOT MATCH the search between an index and .csv file

Ex - this returns the values that are good but i don't want to see these:

index=myindex TAGGING="*Agent*" | dedup DNS | join type=inner DNS [ | inputlookup linuxhostnames.csv | rename hostname as DNS]

 

whereas, I tried the following - this takes slightly longer to return the results but also returns only the matching values instead of the NOT MATCHING

| inputlookup linuxhostnames.csv | rename hostname as DNS | search NOT [search index=myindex| fields DNS | format ]

 

Will appreciate some guidance here.

 

Thank you

I don't get it why this works but it does:

| inputlookup linuxhostnames.csv | rename hostname as DNS | search [search index=myindex| fields DNS | format ]

Now, I only get results that DO NOT MATCH. However, the search is slow. Would there be a faster way to do this?
