README

        
this repo contains some codes to cover the life cycle of data in a simulated IoT scenario.

The process is:

- data generation ("datagenerator" package)

  - use JMX API to get the CPU and memory measurements of your computer.

  - (TODO) use PLC4J to get data from a modbus-protocol based PLC.

- data collection ("collect" package)

  - collect the above data into Kafka

  - collect the above data into MQTT server

  - collect the above data into IoTDB directly.

  

- data store

  - store all data into IoTDB

  

- data query ("accessdata" package)

  - query data from IoTDB.

  

  

- data analyze ("analyze" package)

  - analyze TsFile data that written by IoTDB.

    - To get one or more TsFiles, you may need to run an IoTDB-client.sh and execute "flush" command

     first. Then, you can copy the file path to `SparkSQLAnalyzer` file.

- data visualization

## how to use EMQ 

* deploy EMQ: https://github.com/emqx/emqx/releases/tag/v4.0-alpha.1

* start EMQ: ./bin/emqx start

* deploy IoTDB: ./sbin/start-server.sh

* start IoTDB server: ./sbin/start

* run InitStorageGroup

* launch EMQXConsumerStore

* uncomment " writer = new EMQXSender(); writer.connect("127.0.0.1", 1883);" in DataGenerator

* start DataGenerator

* start IoTDB client: ./sbin/start-client.sh

* select data: select * from root;
