DataOrg

I have a list of server in lookup file and I want to create an alert.
The list of server names in the lookup file(around 90 servers) and I need to pass the value in the main query from the lookup file.

The column server has a value with around 90servers so I need to pass the 90 servers values in the search.

index=foo [| inputlookup yourlookup.csv OUTPUTNEW hostFieldFromLookup AS host | fields host | format host]

Which will turn into

index=foo (host=hostname1 OR host=hostname2 OR ...)

can you share sample values of lookup

|inputlookup production_sites

check if this above query gives output

|inputlookup production_sites where Type="Data"|fields Type

this query only give Type="data" as field I don't hink if thats you are looking for
as fields command limits the output to show only specific fields in this case as Type
