biz.paluch.logging.gelf.wildfly.WildFlyJsonFormatter

public class WildFlyJsonFormatter
extends org.jboss.logmanager.ExtFormatter

Log-Formatter for JSON using fields specified within GELF. This formatter will produce a JSON object for each log event. Example: { "NDC": "ndc message", "timestamp": "1439319236.722", "SourceClassName": "biz.paluch.logging.gelf.wildfly.WildFlyGelfLogFormatterTest", "SourceMethodName": "testDefaults", "level": "6", "SourceSimpleClassName": "WildFlyGelfLogFormatterTest", "facility": "logstash-gelf", "full_message": "foo bar test log message", "short_message": "foo bar test log message", "MySeverity": "INFO", "LoggerName": "biz.paluch.logging.gelf.wildfly.WildFlyGelfLogFormatterTest", "Thread": "main", "MyTime": "2015-08-11 20:53:56,0722" } Following parameters are supported/needed:

• lineBreak (Optional): End of line, defaults to \n
• fields (Optional): Comma-separated list of log event fields that should be included in the JSON. Defaults to Time, Severity, ThreadName, SourceClassName, SourceMethodName, SourceSimpleClassName, LoggerName, NDC
• originHost (Optional): Originating Hostname, default FQDN Hostname
• 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
• mdcProfiling (Optional): Perform Profiling (Call-Duration) based on MDC Data. See MDC Profiling, default false
• facility (Optional): Name of the Facility, default gelf-java
• 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. mdc.*,[mdc|MDC]fields
• dynamicMdcFieldTypes (Optional): Pattern-based type specification for additional and MDC fields. Key-value pairs are comma-separated. Supported types: String, long, Long, double, Double. Eg. my_field.*=String,business\..*\.field=double
• 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 formatter:

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