Enabling the processor groups from NiFi UI

After Apache NiFi is stared, you can access its user interface to set up the environment for File Collector. Apache NiFi is used for data flow for all File-based Technology Packs. Every installed pack has its own processor group that must be enabled and started for data processing.

1. Open a web browser and type the following URL:

   http://<node_hostname>:30026/nifi

   Where,

   • <node_hostname> is the hostname of any node in your cluster.
   • 30026 is the port number of the NiFi Service on the node where it is installed.

   You can see the following UI that has a blank canvas to orchestrate a data flow:

   All the processor groups

2. Right-click the processor group and select Configure > CONTROLLER SERVICES.

   You can see all the controller services and their details in your data flow in a table.

3. Click the Enable icon ( ) and enable all the controller services.
4. Click the processor group and select Start to start the data collection.
