I have tried various suggestions from this site but I'm unable to get the desired results.
A 3rd party installs UF's (Universal Fowarders) and provides a csv list of hosts that have been deployed. I have this list loaded into Splunk as a csv lookup file.
What I need to achieve is show the host name from the csv file where there is no match in search results, it also must deal with case insensitive.
The csv is very simple
The result should be the hosts that are yet to show in the search results so a report can be run and delivered to the vendor to resolve.
What I have tried so far is similar to this, but does not deal with case and I'm not 100% sure its giving accurate results.
| inputlookup uf_deploy.csv | search NOT [search index=*_linux OR index=wineventlog host=* | dedup host | fields host]
Any help would be great.
| inputlookup uf_deploy.csv | eval host=lower(host) | search NOT [ | metadata type=hosts index=linux OR index=wineventlog | eval host=lower(host) | fields host ]
