The Graylog Extended Log Format (GELF) is a log format.

The Extended Log Format (GELF) is a log format that avoids the shortcomings of classic plain syslog:

  • Limited to length of 1024 bytes – Not much space for payloads like backtraces
  • No data types in structured syslog. You don’t know what is a number and what is a string.

  • No compression

There are a number of software libraries that can be used to produce logs in GELF, e.g. .
