How to filter data in an input lookup table?

Hey Splunk People,

 

I'm running a search against a CSV file:

|inputlookup "GSOCdata_230717.csv" | fields source_address, destination_address, protocol_id, destination_port, psrsvd_gc | stats sum(psrsvd_gc) as count by source_address, destination_address, protocol_id, destination_port

 

This builds a table w/ the specified data types contained in the CSV file. Can I filter my data to a smaller output table? I'd like to exclude certain IP addresses from the output of this command. I've tried using a CIDR notation of my address space, but it just chokes.. I've tried .. piping to "eval source_address=172.16.50.0/24" but it doesn't seem to like it..

 

Do you have a suggestion to do this? I worked around this by just building another CSV file with the data filtered to where I want to go, but it seems like this should be solvable in a more elegant way.

 

Thanks,

You can pipe | search source_address=172.16.50.0/24 to your search I order to filter the results

Hope I was able to help you. If so, some karma would be appreciated.

Thanks very much. This worked perfectly. I didn't know that you could pipeline another search like that...
