Step 5 - GELF Logstash Overview
GELF (also known as Graylog Extended Log Format) is a convenient log format that was originally created to provide an alternative to using Syslog. This was done to close the gap between logging in an unstructured format versus the more easily processable structured logging format.
GELF uses a simple JSON string to send structured log messages and application data. Gelf also assists in combating the additional shortcomings that become apparent when using plain Syslog. As plain Syslog is limited to a length of 1024 bytes there is very little remaining space left for backtraces and other payloads.
Due to its support for structured logging, GELF is highly suitable for custom APM setups. GELF log messages contain the following data fields; host, timestamp, version, long and short messages and also provides support for custom fields that can be configured as required.
