Skip lines while indexing

[FRoth]

I am currently experimenting with the nmap scan output format and indexing the scan results with splunk.

I noticed that I got a lot of lines containing "Nmap scan report for 57.57.223.255 [host down]" which means that the line does not contain any useful information for me. I would like to skip all lines containing "host down".

Is there a hack to achieve this?

There is specific functionality for filtering incoming logs, so I wouldn't consider it a "hack" 🙂

Have a look at the following docs page that explains how to achieve this: http://docs.splunk.com/Documentation/Splunk/latest/Deploy/Routeandfilterdatad#Filter_event_data_and_...
