This logback appender logs messages to a Graylog server. It's using the official GELF Java client to connect to the remote server. It's inspired and influenced greatly by the Log4j2 GELF Appender.
The appender has several configurable properties:
server(default:localhost)- The host name or IP address of the GELF server
port(default:12201)- The port the GELF server is listening on
hostName(default: the local host name orlocalhostif it couldn't be detected)- The host name of the machine generating the logs
protocol(default:UDP)- The transport protocol to use
includeSource(default:true)- Whether the source of the log message should be included
includeMDC(default:true)- Whether the contents of the Mapped Diagnostic Context should be included
includeStackTrace(default:true)- Whether a full stack trace should be included
includeLevelName(default:false)- Whether the log level's name should be included, e.g. 'WARN', 'INFO' ...
queueSize(default:512)- The size of the internally used queue
connectTimeout(default:1000)- The connection timeout for TCP connections in milliseconds
reconnectDelay(default:500)- The time to wait between reconnects in milliseconds
sendBufferSize(default:-1)- The size of the socket send buffer in bytes. A size of -1 deactivates the send buffer
tcpNoDelay(default:false)- Whether Nagle's algorithm should be used for TCP connections
tcpKeepAlive(default:false)- Whether to try keeping alive TCP connections.
layout(default:"%m %n")- The Layout to use to format the LogEvent; the resulting string will be used as GELF's
short_message(exception stacktraces are not included in this message)
- The Layout to use to format the LogEvent; the resulting string will be used as GELF's
additionalFields- Comma-delimited list of key=value pairs to be included in every message
