You may want to send logs to an ActiveMQ backend system.

Talend Cloud supports the ActiveMQ TCP protocol.

Procedure

  1. Open the <RemoteEngineInstallationDirectory>/etc/org.ops4j.pax.logging.cfg file and add the following lines:

    Example

    log4j2.appender.jms.type = Jms
log4j2.appender.jms.name = JmsAppender
log4j2.appender.jms.destinationBindingName= dynamicQueues/myQueueName1
log4j2.appender.jms.factoryName=org.apache.activemq.jndi.ActiveMQInitialContextFactory
log4j2.appender.jms.factoryBindingName=ConnectionFactory
log4j2.appender.jms.providerURL=tcp://localhost:616162
log4j2.appender.jms.userName=admin 
log4j2.appender.jms.password=admin3
log4j2.appender.jms.layout.type = JsonTemplateLayout
log4j2.appender.jms.layout.eventTemplateUri=${karaf.base.uri}/etc/jsonLogMinTemplate.json
log4j2.appender.jms.layout.stackTraceElementTemplateUri=${karaf.base.uri}/etc/StackTraceElementLayout.json

log4j2.rootLogger.appenderRef.JmsAppender.ref = JmsAppender
  2. Save the file.
  3. Add the Mapped Diagnostic Context (MDC) information to the JSON template file so that the output logs, where applicable, contain the MDC information. This MDC information includes the run ID of a Talend Cloud Management Console task.
    1. In <RemoteEngineInstallationDirectory>/etc, create a file and name it as jsonLogMinTemplateCustom.json.
    2. Add the following lines to this new file to create a MDC resolver:

      Example

      {
 "logMessage": \{"$resolver": "message", "stringified": true},
 "mdc": {
 "$resolver": "mdc"
 },
 "logTimestamp": \{"$resolver": "timestamp", "epoch": {"unit": "millis", "rounded": true}},
 "severity": \{"$resolver": "level", "field": "name"},
 "ticLogLevel": \{"$resolver": "source", "field": "ticLogLevel"},
 "bundle.name": \{"$resolver": "source", "field": "bundle.name"},
 "bundle.version": \{"$resolver": "source", "field": "bundle.version"}
}
  4. Configure your JMS system to use this new jsonLogMinTemplateCustom.json template instead of the default template file jsonLogMinTemplate.json.
1 This is an example. The destinationBindingName could be dynamicQueues/myQueueName or dynamicTopics/myTopicName.
2 This is an example. You need to define your JMS host and its port.
3 This admin is only an example for userName and password.
