Patterns for enabling JSON logging on Camunda BPM Tomcat Distributions.
By default, camunda logs using standard java logging, which means they are difficult to parse and import into other logging systems such as logstash, greylog, etc. JSON is generally considered the interop standard for logs.
A image which pulls Camunda 7.20.0-Tomcat and extends the image with proper configuration for Logging in a JSON format.
JSON logging is provided using the logstash-logback-encoded-7.4.jar and the relevant dependencies for SLF4j-api, logback, jul-to-slf4j.
Logback and slf4j-api dependencies are bumped up to be compatible with Camunda 7.20.0.
Note that in order to send the Tomcat/catalina logs into the JSON encoders, the SLF4JBridgeHandler (jul-to-slf4j-2.0.11.jar) is used within the global logging.properties file. See the handlers documentation for notes about performance. In order to mitigate the performance issues outlined in the Handler's documentation, the LevelChangePropagator is added into the logback configuration. See the logback documentation for further notes about LevelChangePropagator's usage.
âť— It is very important for Camunda Tomcat distribution logging that the LevelChangePropagator is used as described above! It is already provided in the logback configuration file located in the docker/camunda/conf/logback folder. If you make changes to this file, make sure to keep the LevelChangePropagator settings. âť—
The pattern is simple:
- Pull the Camunda BPM Platform 7.20.0 Tomcat image from DockerHub
- Extend the image with relevant JSON logging configurations and Jars
- Return a finalized image that is "the same" as the source image from Camunda's dockerhub, but with the added configuration and jars.
A centralized package has been generated. This package provides a single jar with all of the required jars needed for JSON logging using logback.
docker build -t yourorganization/camunda-bpm-platform:tomcat-7.20.0-json-logging .
docker run --name camunda -p 8080:8080 yourorganization/camunda-bpm-platform:tomcat-7.20.0-json-logging
docker compose up --build
In the default logback.xml configuration, there has been a conditional statement added to support easy to use logging in Pretty-Print formatting. This is typically used for development purposes:
PRETTY_JSON_LOG=true will enable the pretty-print. By default, the env value is set to false.
Example:
docker run --name camunda -p 8080:8080 -e PRETTY_JSON_LOG=true yourorganization/camunda-bpm-platform:tomcat-7.20.0-json-logging
In order to provide a custom logback.xml file, it is suggested that you use Docker Volumes; where the volume points to /camunda/conf/logback folder. Within this folder you will provide the logback.xml file with your configuration. See the docker/docker/conf/logback.logback.xml file for a working example/the default logback.xml file that is used.
A 30 second refresh has been configured on the logback.xml file. If the file is changed through a volume, you can make updates to the logging configuration without having to restart the Camunda docker container. See the logback.xml file for further details.
By default pretty-print of the JSON is disabled. This is to ensure maximum compatibility for production use of the base image.
In order to enable pretty-print of JSON (should only be used for debug/development purposes, due to performance impacts): in the camunda/conf/logback/logback.xml file, within the json <appender>, un-comment the line:
<jsonGeneratorDecorator class="net.logstash.logback.decorate.PrettyPrintingJsonGeneratorDecorator"/>The PrettyPrintingJsonGeneratorDecorator will then process the json into a pretty-print format within the console.
A Env variable has been added into the image (PRETTY_JSON_LOG=false) which can be set to true to enable Pretty-Print Json Logging. This configuration is found through the logback.xml. See the Running Image section of this document for further information.
See the logstash-logback-encoded Timezone documentation for details on how to customize the logback configuration for timezone conversions.
The pattern uses the Logstash-Logback-Encoder library v7.4. See the Readme of the library for further configuration options.
Logs are being sent into the docker console. It will still be up to your deployment to configure docker logging to be in a JSON format.
$ docker run --name camunda -p 8080:8080 yourorganization/camunda-bpm-platform:tomcat-7.20.0-json-logging
