here is my current search that im running
index=test outbound "/22" ciscodsthost!=10.0.0.1| RENAME ciscodsthost AS Scrhost | RENAME ciscosrchost AS Dsthost| stats count by Scrhost, Dst_host
I want to add a inputlookup file.csv that has IPs inside of it that i want to exclude from that search. I want it to do something like -
index=test outbound "/22" ciscodsthost!=10.0.0.1 NOT [|inputlookup file.csv] | RENAME ciscodsthost AS Scrhost | RENAME ciscosrchost AS Dsthost| stats count by Scrhost, Dst_host
i have already uploaded the CSV file to splunk lookups directory and tested that splunk can pull it in. I just cant get the results to filter correctly.
