Splunk Search

How can I exclude list of IPs?



I have a .csv with 2 columns: hostname and ip.

How can I exclude the IPs from that list ?

Tried something like this, but it doesn't work: src_ip="[|inputlookup ip_list.csv | fields ip]"

The inputlookup subsearch will return a list of IPs in key=value format.  It'll look something like

(ip= OR ip= OR ip=

Taken literally, it's an include list - Splunk will return only events with those ip values.  Use NOT to make it an exclude list.

index=foo NOT [|inputlookup ip_list.csv | fields ip]

This assumes index foo has a field called "ip".  If it doesn't then the subsearch will need a rename command.

If this reply helps you, Karma would be appreciated.
