A minimalistic adapter for github.com/gliderlabs/logspout to write to Logstash TCP. Supports

• multi-line log grouping
• udacity metadata

Log lines identified as JSON preserve the app-specific fields when shipped to Logstash.

Follow the instructions in https://github.com/gliderlabs/logspout/tree/master/custom on how to build your own Logspout container with custom modules. Basically just copy the contents of the custom folder and include:

import (
  _ "github.com/udacity/logspout-logstash"
  _ "github.com/gliderlabs/logspout/transports/udp"
)

in modules.go.

Use by setting ROUTE_URIS=logstash://host:port to the Logstash host and port for TCP.

In your logstash config, set the input codec to json e.g:

input {
  tcp {
    port => 5000
    codec => json
  }
}
