All Implemented Interfaces:

ErrorReporter

public class WildFlyGelfLogHandler
extends GelfLogHandler

Logging-Handler for GELF (Graylog Extended Logging Format). This Java-Util-Logging Handler creates GELF Messages and posts them using UDP (default) or TCP. Following parameters are supported/needed:

• host (Mandatory): Hostname/IP-Address of the Logstash Host
  • (the host) for UDP, e.g. 127.0.0.1 or some.host.com
  • See docs for more details
• enabled (Optional): Whether this handler is enabled, default true
• port (Optional): Port, default 12201
• originHost (Optional): Originating Hostname, default FQDN Hostname
• extractStacktrace (Optional): Post Stack-Trace to StackTrace field, default false
• extractStackTrace (Optional): Post Stack-Trace to StackTrace field (true/false/throwable reference [0 = throwable, 1 = throwable.cause, -1 = root cause]), default false
• filterStackTrace (Optional): Perform Stack-Trace filtering (true/false), default false
• includeLogMessageParameters (Optional): Include message parameters from the log event (see LogRecord.getParameters(), default true
• includeLocation (Optional): Include source code location, default true
• facility (Optional): Name of the Facility, default gelf-java
• level (Optional): Log-Level, default INFO
• filter (Optional): Class-Name of a Log-Filter, default none
• additionalFields(number) (Optional): Post additional fields. Eg. fieldName=Value,field2=value2
• additionalFieldTypes (Optional): Type specification for additional and MDC fields. Supported types: String, long, Long, double, Double and discover (default if not specified, discover field type on parseability). Eg. field=String,field2=double
• mdcFields (Optional): Post additional fields, pull Values from MDC. Name of the Fields are comma-separated Application,Version,SomeOtherFieldName
• dynamicMdcFields (Optional): Dynamic MDC Fields allows you to extract MDC values based on one or more regular expressions. Multiple regex are comma-separated. The name of the MDC entry is used as GELF field name. Eg. mdc.*,[mdc|MDC]fields
• includeFullMdc (Optional): Include all fields from the MDC, default false

MDC Profiling

MDC Profiling allows to calculate the runtime from request start up to the time until the log message was generated. You must set one value in the MDC:

• profiling.requestStart.millis: Time Millis of the Request-Start (Long or String)

Two values are set by the Log Appender:

• profiling.requestEnd: End-Time of the Request-End in Date.toString-representation
• profiling.requestDuration: Duration of the request (e.g. 205ms, 16sec)

The publish(LogRecord) method is thread-safe and may be called by different threads at any time.
