usage of the GELF format

The Graylog Extended Log Format (GELF) is a log format that avoids the shortcomings of classic plain Syslog and is perfect for logging from your application layer. It comes with optional compression, chunking, and, most importantly, a clearly defined structure. The Input of GELF messages can be UDP, TCP, or HTTP. Additionally, a queue is possible.
