Accessing logs

The workflow deployment logs are located in the % DDUAppFolder %\bin\logs folder, where DDUAppFolder is the location of the DDU folder.

Note: The naming convention used for workflow deployment logs is DeploymentLog _%WORK-FLOW-NAME%_% TIMESTAMP %.csv,

where:

  • DeploymentLog is the name of the deployment log.
  • TIMESTAMP is the log time.

The workflow deployment logs (.csv) contain any of the following:

  • Successful deployments

  • Communication errors

  • Deployment errors

DDU uses the Apache® Log4j™ software API to create the application and deployment logs. The configuration file for the logs can be found in DDUAppFolder \config\log4j‑config.xml, where DDUAppFolder is the location of the DDU folder. For more information, see Configuring log settings.

By default, the log files are saved in the folder for the DDU executable files.

DDU creates the following logs:

  • Application log (ddu.log)—If set to DEBUG, then this log file helps developers track each request and response between the device and the computer. Threads of requests and responses are classified according to device IP addresses.

  • Deployment log—This log file helps users view device details and status of solutions and licenses being installed. The file also provides a message to confirm that deployment is successful. For easier sorting of device status, the log file is created in CSV format, with the IP address of the device as the first column.

    Checking for deployment errors

    1. Open the deployment.csv file. The log file can be found in DDUAppFolder \bin\log, where DDUAppFolder is the location of the DDU folder.

    2. Filter the log file for errors.

    Note: If the log file is set to INFO, then the file contains the same messages as the status window does.
