This project is now archived, after a decade of maintenance, with 36 releases and several occasional contributors. The project is feature complete, and we see little issue traffic. With me being the sole maintainer, it is about time to turn off the lights here and move on to free up time for other duties. K, thx, good bye.
Provides logging to logstash using the Graylog Extended Logging Format (GELF 1.0 and 1.1) for using with:
logstash-gelf requires as of version 1.14.0 Java 7 or higher. Version 1.13.x and older require Java 6.
See also http://logging.paluch.biz/ or http://www.graylog2.org/resources/gelf/specification for further documentation.

</appender>Log4j v2 supports an extensive and flexible configuration in contrast to other log frameworks (JUL, log4j v1). This allows you to specify your needed fields you want to use in the GELF message. An empty field configuration results in a message containing only
- timestamp
- level (syslog level)
- host
- facility
- message
- short_message
You can add different fields:
- Static Literals
- MDC Fields
- Log-Event fields (using Pattern Layout)
In order to do so, use nested Field elements below the Appender element.
<Field name="fieldName1" literal="your literal value" /><Field name="fieldName1" mdc="name of the MDC entry" /><DynamicMdcFields regex="mdc.*" />In contrast to the configuration of other log frameworks log4j2 config uses one DynamicMdcFields element per regex (not separated by comma).
See also: Pattern Layout
Set the desired pattern and the field will be sent using the specified pattern value.
Additionally, you can add the host-Field, which can supply you either the FQDN hostname, the simple hostname or the local address.
| Option | Description |
|---|---|
| host{["fqdn" "simple" "address"]} |
Outputs either the FQDN hostname, the simple hostname or the local address. You can follow the throwable conversion word with an option in the form %host{option}. %host{fqdn} default setting, outputs the FQDN hostname, e.g. www.you.host.name.com. %host{simple} outputs simple hostname, e.g. www. %host{address} outputs the local IP address of the found hostname, e.g. 1.2.3.4 or affe:affe:affe::1. |
