Loggregator Emitter

About

This gem provides an API to emit messages to the loggregator agent from Ruby applications.

Create an emitter object with the loggregator router host and port, a source name of the emitter, and a shared secret (for signing).

Call emit() or emit_error() on this emitter with the application GUID and the message string.

A valid source name is any 3 character string. Some common component sources are:

API (Cloud Controller)
RTR (Go Router)
UAA
DEA
APP (Warden container)
LGR (Loggregator)
