Can I block a sourcetype from being indexed?

[dhaffner]

We have a huge sudden input of a specific sourcetype and it is overloading the license. Can we somehow block it or set it to drop so they do not get indexed and make us go over our license? Any ideas welcome, but we do not use iptables and are not able to block it at the network level, so it would have to be something in Splunk.

Thanks

For some reason, this seems to have stopped working. Any other ideas? Thank you!

A simple configuration like this should work. Depending on if you have forwarders (and if there are lightweight or not) may change where you need to deploy these settings to.

props.conf

[my_out_of_control_sourcetype]
TRANFORMS-dropall = drop_events

transforms.conf

[drop_events]
DEST_KEY = queue
REGEX   = .
FORMAT   = nullQueue

Simply replace "my_out_of_control_sourcetype" with the name of the sourectype you want to silence.

That's weird. It shouldn't have worked and then stopped working. Have you confirmed that no other part of your configuration changed? Are you blocking based on sourcetype or based on a host entry? Posting your exact config may be helpful too.
