Getting Data In

How can I find out what events get sent to the nullQueue when I try to filter events on a forwarder?

Hi

I am trying to filter events on a LightWeightForwarder, but they don't get dropped. Is there a way to debug this?

I have defined the following in an app which I deploy from the indexer.

In props.conf
[source::/var/opt/app/logs/navajo.log]
TRANSFORMS-set= setnull

In transforms.conf
[setnull]
REGEX=toolbar
DEST_KEY=queue
FORMAT=nullQueue

The events containing "toolbar" keep coming. Even if I set the regex to "REGEX=." the events still arrive on the indexer.

Any ideas?

LWF does not perform the indexing, and therefore, does not do anything with the event but forward it. You should place this on the receiver. Your syntax is correct, just need to move the config to the receiver. Make sure you restart.

LWF can't filter because it doesn't look at the the incoming data. Please read here for explanation: http://www.splunk.com/wiki/Where_do_I_configure_my_Splunk_settings%3F
