Following settings can be used:

Attribute Name Description Default
enabled Whether this handler is enabled true
host Hostname/IP-Address of the Logstash host. The host field accepts following forms:
  • tcp:hostname for TCP transport, e. g. tcp:127.0.0.1 or tcp:some.host.com
  • udp:hostname for UDP transport, e. g. udp:127.0.0.1, udp:some.host.com or just some.host.com
  • redis://[:password@]hostname:port/db-number#listname for Redis transport. See Redis transport for logstash-gelf for details.
  • redis-sentinel://[:password@]hostname:port/db-number?masterId: masterId#listname for Redis transport with Sentinel lookup. See Redis transport for logstash-gelf for details.
none
port Port of the Logstash host 12201
version GELF Version 1.0 or 1.1 1.0
originHost Originating Hostname FQDN Hostname
extractStackTrace Send the Stack-Trace to the StackTrace field (true/false) false
filterStackTrace Perform Stack-Trace filtering (true/false) false
includeLogMessageParameters Include message parameters from the log event true
includeLocation Include source code location true
facility Name of the Facility logstash-gelf
mdcProfiling Perform Profiling (Call-Duration) based on MDC Data. See MDC Profiling for details false
level Log-Level threshold INFO
filter Class-Name of a Log-Filter none
additionalFields Send additional static fields. The fields are specified as key-value pairs are comma-separated. Example: additionalFields: fieldName: Value,fieldName2: Value2 none
additionalFieldTypes 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 discover for all additional fields
mdcFields Send additional fields whose values are obtained from MDC. Name of the Fields are comma-separated. Example: mdcFields: Application,Version,SomeOtherFieldName none
dynamicMdcFields Dynamic MDC Fields allows you to extract MDC values based on one or more regular expressions. Multiple regexes are comma-separated. The name of the MDC entry is used as GELF field name. none
dynamicMdcFieldTypes Pattern-based type specification for additional and MDC fields. Key-value pairs are comma-separated. Example: my_field.*=String,business\..*\.field=double none
includeFullMdc Include all fields from the MDC. false
maximumMessageSize Maximum message size (in bytes). If the message size is exceeded, the appender will submit the message in multiple chunks. 8192
timestampPattern Date/time pattern for the Time field yyyy-MM-dd HH:mm:ss,SSS

The only mandatory field is host. All other fields are optional.

Preliminary Steps

If you want to get started with the logstash-gelf support for WildFly Swarm/Thorntail, you will need to integrate logstash-gelf as a module within the server. It is possible to create the module manually, but it's easier to use the prepackaged binary and extract the module.xml file. Please follow the steps to integrate the module:

  1. Obtain the logging module from [Maven](http://search.maven.org/remotecontent?filepath: biz/paluch/logging/logstash-gelf/1.15.1/logstash-gelf-1.15.1-logging-module.zip) or Github
  2. Extract the module to and copy module-thorntail.xml to src/main/resources/modules/biz/paluch/logging/main/module.xml.
  3. Configure the logging subsystem using src/main/resources/project-stages.yml:
