Hi,

It will be easier if you create a filter based on the source if you are talking about just one device.

To be more precise, create a very generic filter that breaks down the main syslog and gives you the host IP/name .  
Then create a new filter based on that field. it will be something like:

`if [host] == "the_host_you_want" { grok {`

Of course grok can be anything else and the field will be named whatever you want.

Hope it helps.
