Hello,

I have 2 CSV lookups updating several times a day.  One (A) is from CMDB with the entire list of assets (hostname, ip, user, os, etc).  The other (B) is a list of installed clients for some product, also containing the hostname.  I would like to get a search/dashboard that lists hosts in A that are not found in B with some of  additional fields.  Have no found a way to do with with 2 lookups, any ideas?  Thanks!

Lookup CSV A: Host1, Host2, Host3
Lookup CSV B: Host1, Host3
Search output: Host2
