Viewing Runtime Logs

Runtime logs provide detailed records of flow execution, capturing every step from start to finish. They include information such as start time, end time, running status, logs, and any errors encountered.

These logs help users monitor workflows, identify faults, and improve performance.

This section describes how to view runtime logs of a composite application.

Configuring Runtime Logs

  • To configure runtime logs for composite applications, enable LTS and create log groups and log streams first. For details, see Log Management Overview.
  • Runtime log limits:
    1. Each log entry is limited to 10 KB; excess data will be discarded.
    2. Under high load, to maintain performance, some logs may be omitted.
  1. Log in to the new ROMA Connect console.
  2. In the navigation pane on the left, choose Application. On the page displayed, click the target composite application.
  3. If the composite application is not started:
    1. On the composite application page, click Start.
    2. In the displayed dialog box, select an instance.
    3. Enable LTS Logs.
    4. Select an LTS log group and a log stream. If no log group or stream is available, click View Log Group or View Log Stream to go to the LTS console.
    5. Click OK to start the composite application.
  4. The composite application has been started:
    1. On the composite application page, click Runtime Log.
    2. Click Enable.
    3. In the displayed dialog box, enable LTS.
