Factory method for creating a GelfTransport provider within the plugin manager.

Parameters:

name - The name of the Appender.

filter - A Filter to determine if the event should be handled by this Appender.

layout - The Layout to use to format the LogEvent defaults to "%m%n".

ignoreExceptions - The default is true, causing exceptions encountered while appending events to be internally logged and then ignored. When set to false exceptions will be propagated to the caller, instead. Must be set to false when wrapping this Appender in a FailoverAppender.

server - The server name of the GELF server, defaults to localhost.

port - The port the GELF server is listening on, defaults to 12201.

hostName - The host name of the machine generating the logs, defaults to local host name or localhost if it couldn't be detected.

protocol - The transport protocol to use, defaults to UDP.

tlsEnabled - Whether TLS should be enabled, defaults to false.

tlsEnableCertificateVerification - Whether TLS certificate chain should be checked, defaults to true.

tlsTrustCertChainFilename - A X.509 certificate chain file in PEM format for certificate verification, defaults to null

queueSize - The size of the internally used queue, defaults to 512.

connectTimeout - The connection timeout for TCP connections in milliseconds, defaults to 1000.

reconnectDelay - The time to wait between reconnects in milliseconds, defaults to 500.

sendBufferSize - The size of the socket send buffer in bytes, defaults to -1 (deactivate).

tcpNoDelay - Whether Nagle's algorithm should be used for TCP connections, defaults to false.

tcpKeepAlive - Whether to try keeping alive TCP connections, defaults to false.

includeSource - Whether the source of the log message should be included, defaults to true.

includeThreadContext - Whether the contents of the ThreadContext should be included, defaults to true.

includeStackTrace - Whether a full stack trace should be included, defaults to true.

includeExceptionCause - Whether the included stack trace should contain causing exceptions, defaults to false.

additionalFields - Additional static comma-delimited key=value pairs that will be added to every log message.

Returns:

a new GELF provider
