The admin toolkit contains command line utilities for administrators to support NiFi maintenance in standalone and clustered environments. These utilities include:
Notify - The notification tool allows administrators to send bulletins to the NiFi UI using the command line.
Node Manager - The node manager tool allows administrators to perform a status check on a node as well as to connect, disconnect, or remove nodes that are part of a cluster.
File Manager - The file manager tool allows administrators to backup, install or restore a NiFi installation from backup.
The admin toolkit is bundled with the nifi-toolkit and can be executed with scripts found in the bin folder.
