Need help extracting a hostname from a source path

Hey guys,

I'm a noob at props and transforms.

Trying to basically extract a hostname from a sourcepath.

Example:

/var/log/fms/host/blah/

I would like to extract "host" and use that as the hostname for the source log.

Here is how I am doing it so far:

[host-extract]
SOURCE_KEY = MetaData:Source
REGEX = (\/var\/log\/fms\/)([0-9a-zA-Z\.\-_/]+)?\/
DEST_KEY = MetaData:Host
FORMAT = $2

I also setup the following in props for this transform:

[FMS_LF]
TRANSFORMS-host = host-extract

However seems like its not working...

Any thoughts? Is my regex not right?

Any help you can provide would be great.

Thanks.

Brian

An even easier approach might be host_segment in inputs.conf. Using your example,

[monitor:///var/log/fms]
host_segment=4
sourcetype=fms_source_type
