Publish Flow to Agents


You can download CEM and NiFi Registry from Cloudera.   You need the Registry to be able to save and version the flows you will be deploying.

For a simple proof of concept, development test, you can setup both without needing a full fledged database.   You can use the H2 database for learning how to use the system.

I installed CEM on a few versions of Ubuntu and on Centos 7.

First thing you need to do is to install NiFi Registry, run it and create a bucket for EFM to use.

CEM Configuration Basics

conf/   - turn on nifi registry
Create a bucket

EFM Settings
# Web Server Properties
#  address: the hostname or ip address of the interface to bind to; to bind to all, use


New Features in MiniFi 0.6.0 C++ Agent

Python Processors

These are great, but first you will need to make sure you have Python installed and know where your Python modules are:

python -c "import site; print(site.getsitepackages())"python -m sitepython -m site --user-site

You will need a precompiled C++ agent for your environment or build it yourself.   You can also choose the Java agent if you do not wish to compile C++.   The C++ agent is smaller with a smaller footprint.

Configuring a MiNiFi Java Agent to Talk to EFM

# MiNiFi Command & Control Configuration
# C2 Properties
# Enabling C2 Uncomment each of the following options
# define those with missing options
## define protocol parameters
## heartbeat in milliseconds.  defaults to once a second
## define parameters about your agent
# Optional.  Defaults to a hardware based unique identifier
## Define TLS security properties for C2 communications

Configuring a MiNiFi C++ Agent to Talk to EFM



EFM Ports

EFM Server UI 10080
NiFi Registry 18080
CoAP 8989



















You will also want an Apache NiFi 1.9.x server to receive calls from the MiNiFi Agents.

Exploring Apache NiFi 1.10: Stateless Engine and Parameters

Exploring Apache NiFi 1.10:   Stateless Engine and Parameters Apache NiFi is now available in 1.10!

You can now use JDK 8 or JDK 11!   I am running in JDK 11, seems a bit faster.

A huge feature is the addition of Parameters!   And you can use these to pass parameters to Apache NiFi Stateless!

A few lesser Processors have been moved from the main download, see here for migration hints:

Ingesting Drone Data From DJII Ryze Tello Drones Part 1 - Setup and Practice

Ingesting Drone Data From DJII Ryze Tello Drones Part 1 - Setup and Practice In Part 1, we will setup our drone, our communication environment, capture the data and do initial analysis. We will eventually grab live video stream for object detection, real-time flight control and real-time data ingest of photos, videos and sensor readings. We will have Apache NiFi react to live situations facing the drone and have it issue flight commands via UDP. In this initial section, we will control the drone with Python which can be triggered by NiFi. Apache NiFi will ingest log data that is stored as CSV files on a NiFi node connected to the drone's WiFi. This will eventually move to a dedicated embedded device running MiniFi. This is a small personal drone with less than 13 minutes of flight time per battery. This is not a commercial drone, but gives you an idea of the what you can do with drones. Drone Live Communications for Sensor Readings and Drone Control You must connect to the drone…
