Downloading NiFi application log

You can download the NiFi application log from the CDF Deployment Manager to use it for troubleshooting.

This feature allows you to download the NiFi application log that is currently being written. As the log file is rotated and the old file is archived once the file size reaches 10 MB, this is the theoretical maximum you can download using this method. For information on downloading archived log files, see Diagnostic bundle collection.
You need DFFlowAdmin permission to perform this action.
  1. On the Dashboard select the deployment for which you want to download the NiFi application log.
  2. Select Actions > Manage Deployment.
    You are redirected to the Deployment Manager page.
  3. Select Actions > Download NiFi Log.
The current NiFi application log is downloaded to your computer in tar.gz format.
