Splunk Search

exclude IPs from results

Hi,
I want to exclude some IP addresses which are about over 100 in my search.
Seems silly to type NOT NOT NOT.. 100+ times.

source="dbmon-tail://netmanias/splunk_ads_click" NOT "61.247.204.36" NOT "61.247.204.38" NOT "61.247.204.37" NOT "61.247.204.39" NOT "61.247.204.35......"

Is there any good idea?

yes! use a combination of a lookup file and a subsearch.

Put all your IP addresses into CSV file, called "ipAdd.csv" for example with the following contents:

match,ip
1,61.247.204.36
1,61.247.204.38
1,61.247.204.37
1,61.247.204.39
1,61.247.204.35
....

Create a transforms.conf file with the following stanza:

[ipAdd]
filename = ipAdd.csv

Check that Splunk likes this configuration/format by putting the following into a search box (note that the "|" should be the first character):

| inputlookup ipAdd

Assuming this returns the contents of the file, you can construct your search as follows:

source="dbmon-tail://netmanias/splunk_ads_click" NOT [|inputlookup ipAdd | rename ip AS query | fields query]

If the IP addresses are in a specific range you could use the CIDR notation like this:
source="dbmon-tail://netmanias/splunk_ads_click" NOT 61.247.204.0/24
