Getting Data In

filtering on host

I've setup a heavy forwarder so that some feeds are going to one set of indexers, and another feed is going to a different set of indexers. I also setup a filter, so that only certain events are indexed (the rest are discarded). Now, I want to filter specifically on hosts that match a regex. How do I do that? It appears that the regex in transforms.conf works on the entire event, not just the host. Is there a way to do this?

When you say you want to "filter", you are implying you want to take action (change indexer, drop data) based on the regex of the host? You would do this by specifying the host-matching pattern for the host in props.conf, which is regex-based (with the exception of ..., ., and *).

props.conf

[host::(my.+[1-6])|(otherhost[0-9]{0,})]
TRANSFORMS-drop = drop_event

transforms.conf

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

Essentially, I want a whitelist. OK. I think that I get it. I'll give it a whirl...
