Downloading NiFi application log

You can download the NiFi application log from the 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 MBs, this is the theoretical maximum you can download using this method. For information on downloading archived log files, see Diagnostic bundle collection.
