I'm seeing this message repeating over and over in the traffic controller
Unable to recursively find keys with prefix

Here's my config:

"Syslog" : "",
"Zone": "CRAZY_TOWN",

"UaaHost": "http://localhost:8080",

I have all the components running locally, using cf-release 215. I have two
1. what's causing this error?
2. if all I want out of the system are logs (via cf logs command), can I
get away with just having a traffic controller and dea agent running or do
I need metron and doppler?
