View the Log for a Mule-App Project in Flow Designer

You can view the log for a Mule-app project. Doing so can be helpful when you test an app or when you are working with MuleSoft support to diagnose problems running an app.

The log file lists two primary categories of message:

System messages

These are messages from CloudHub. Here are some example messages that show CloudHub assigning a worker to a project and then starting the application in that project.

What to do next

  • To copy a line of the log, click the Copy option to its left.

  • To delete the content of the log file, click the dots to the right of the Logs label and select Clear Logs.

  • To view the log file in Runtime Manager, click the dots to the right of the Logs label and select View in Runtime Manager.

    If you have not specified a default environment for your profile in Anypoint Platform, you’re asked to specify one. After you do that, return to the flow-design canvas and select View in Runtime Manager again.

    In Runtime Manager, you can view messages in the System log separately from the messages for the worker that is assigned to your project.
