Logging with Gelf

[Jan Strube]

Hi,

has anyone managed using gelf as logging handler?

I added this to project-stages.yml:

swarm:
    logging:
        root-logger:
            level: INFO
        custom-handlers:
            GELF:
                level: DEBUG
                attribute-class: biz.paluch.logging.gelf.wildfly.WildFlyGelfLogHandler
                module: biz.paluch.logging
                properties:
                    host: udp:localhost
        loggers:
            com.foo:
              level: DEBUG
              handlers:
                  - GELF

and to pom.xml:

<dependency>
    <groupId>biz.paluch.logging</groupId>
    <artifactId>logstash-gelf</artifactId>
    <version>1.11.1</version>
    <classifier>logging-module</classifier>
</dependency>

But I get an:

ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "logging"),
    ("custom-handler" => "GELF")
]): java.lang.IllegalArgumentException: WFLYLOG0019: Failed to load module 'biz.paluch.logging' for handler 'GELF'

Thanks
Jan

Jan,

Does your project have a module.xml for biz.paluch.logging in src/main/resources/modules of the project?

If not, that's likely the cause.

Essentially there needs to be a module.xml to map the Maven dependency to a JBoss Module, which is the name you need to set on GELF.module in the yaml.

Take a look at https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/datasource/datasource-war for an example of providing module.xml files.

How did you achive this, because I get the following error, when I integrate it as you described.

The module.xml was wrong. Got it running as described here https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/thorntail/J_R8k3l33Js/_0rLLR26BAAJ
