Introducing ready to use MQTT Broker Plugin

by Ranjith Kumar DSM | Jan 10, 2018 | MQTT Broker, MQTTRoute

A few weeks back we rolled out an update that provides an option to store MQTT Payload into ElasticSearch. In addition, this update also had options to enable customization to send data received from the different edge devices to various storage engines or your own application. Today we want to make the MQTT Broker more ready to use for our customers. Yes we are rolling out ready to use MQTT Broker plugin for MongoDB & ElasticSearch.

These plugins can store data of plain text message and one level of JSON data into the document store. Besides that the JSON string will be federated and stored as a flat key value pair into the document store. The flatter storage will help you draw powerful charts and user friendly graphs in the way you need.

The way of data storage is completely dependent on the way data is generated from the client. So we have provided these plugins under an open Apache license, so that you can customise the MQTT Broker plugin as required for the data.

MQTT Broker Plugin for MongoDB

Mongodb is one of the most widely used Document Storage engine for IOT data analysis. This plugin can be enabled in MQTT Broker and configured to write data into the Mongodb. If you are receiving a complex JSON data from the edge devices, you can customize the code to alter the data for storage.

MQTT Broker Plugin for ElasticSearch

ElasticSearch is a very powerful search engine. Hence, We use ElasticSearch for our IOT Platform and our hosted Device Manager. And also we provide a default integration with Elastic in MQTT Broker. We are also publishing the code for the customers to make changes as needed for their data format.

We would be happy to help you with storing complex data if needed. We are also working on connectors for AWS Lamda, GE Predix, Apache Hive and more. Do write to support for any assistance or feedback

Visualize IOT Data with Elasticsearch

by Ranjith Kumar DSM | Dec 19, 2017 | MQTT Broker, MQTTRoute

All data collected from the edge devices should be analysed to drive proper decisions. A good tool to visualize IOT Data will help users drive better decisions. Each business want to visualize iot data with their own or comfortable tools as for their convenience.

A complete IOT implementation needs a powerful data processing, user friendly visualization and a quick decision driving notifications. To enable such a complete implementation, MQTT Broker can now talk to any Big data engine to store the data for further processing.

MQTT Broker & ElasticSearch

We added Elastic Search as a default extension into the MQTT Broker. You can just install the Elastic Search and configure the details in the conf/data_store.conf and the MQTT Broker will start writing all the received data into the Elastic Search engine. You can use The default index as mqtt and you can change it in the data_store.conf file. And also you can visualize the data using Kibana powerful visualization tool from the Elastic.co. Most tools today can read data from Elastic to show it in a nice user friendly way.

Handling JSON

MQTT Broker will split the JSON to one level and store it in document store as individual columns, so that it will be easy to query and make decisions.

For example, a data from a HVAC Sensor production_room_sensor_4 in the JSON format will look like.

{“Humidity”:”50%” , “Temperature”:”27°C”, “Time”:”Tuesday, 19 Dec 2017 14:22:33″ }

The same will be stored in a more flat structure for easy construction of visualization Queries. If you are using a more nested JSON for data transfer

sender:production_room_sensor_4, “Humidity”:”50%” , “Temperature”:”27°C”, “Time”:”Tuesday, 19 Dec 2017 14:22:33″

Visualize IOT Data with any Platform

MQTT Broker also send the received data to any of your python program for you to process and store into your own data store

# The parameter data will be in dict format and the keys are ‘sender’,’topic’, ‘message’, ‘unixtime’, ‘timestamp’

def handle_Received_Payload(data):
# Write your code here. Use your connection object to
# Send data to your data store

We will be adding more integrations to the MQTT Broker by default. So that it can used as a plug and play with minimal implementation from the development team.
