NiFi Server UI overview

 — Processor. Responsible for data entry and exit, routing, and manipulation. There are many different types of processors.

 — Input Port. Provide a mechanism for passing data to a process group.

 — Output Port. Provides a mechanism for passing data from a process group to destinations outside the process group.

 — Process group. Used to logically group a set of components to make the flow of data easier to understand and maintain.

 — Remote Process Group. Used similarly to process groups. However, the remote process group refers to the remote NiFi instance.

 — Funnel. Used to combine data from many connections into one connection.

 — Template. Can be created from sections of a flow or imported from other data flows. These templates provide larger building blocks to quickly create a complex flow.

 — Label. Used to attach records to parts of a data flow.

 — the number of nodes in the cluster and the number of nodes currently connected;

 — the number of threads currently active;

 — the amount of data that currently exists in the stream;

 — the number of remote process groups sending data;

 — the number of remote process groups not sending data;

 — the number of active processors;

 — the number of processors stopped;

 — the number of invalid processors;

 — the number of disabled processors;

 — the number of updated process groups;

 — the number of locally modified process groups;

 — the number of stale process groups;

 — the number of locally modified and obsolete process groups;

 — the number of process groups with synchronization error;

 — the timestamp of last update of all information.

 — view and change the configuration of the created flow;

 — enable the flow (commission in the schema);

 — disable the thread (out of action in the schema);

 — start the flow;

 — stop the flow;

 — create a template;

 — load the created template;

 — copy the flow;

 — paste the flow (where allowed);

 — create a processor group (where allowed);

 — change the color of the flow symbol, used to visually highlight different flows;

 — delete the flow.
