Configuring stats and trace message transfer for Talend JobServer

You can specify a port through which Talend Studio fetches the latest stats and trace messages from Talend JobServer for Jobs being executed remotely.

About this task

The stats and trace messages feature is a development level feature.

Generally, it is recommended to disable the stats and trace messages transfer parameter for production environments, to avoid an excessive usage of memory and to protect against connections from outside if the network connections from outside are not already blocked.

Using real-time statistics may result in excessive memory usage on JobServer side. If you observe ZeroMQ related memory leaks, disable stats and trace messages on JobServer. With that, real-time statistics on Talend Administration Center will be unavailable.

Procedure

  1. Go to the directory <root>\conf, where <root> is the Talend JobServer path, and open the TalendJobServer.properties file to edit it.
  2. In the line dedicated to the configuration of the message transfer port, specify a port number. 
    org.talend.remote.jobserver.server.TalendJobServer.PROCESS_MESSAGE_PORT=<port_number>

    The default port is 8555. You can specify any port that is available in the system.

  3. To enable stats and trace message transfer, set the following parameter to true. 
    org.talend.remote.jobserver.server.TalendJobServer.ENABLED_PROCESS_MESSAGE=true
    If the Talend JobServer is deployed on the same machine with the Talend Studio, you can set this parameter to false to disable the service and save your port resources.
  4. Save your changes and restart the Talend JobServer so that the configuration takes effect.
