The time series database IoTDB installation

HertzBeat's historical data storage relies on the time series database IoTDB or TDengine, you can choose one of them to initialize, or not to install (note ⚠️If you don't install it, there will be no historical chart data)

Apache IoTDB is a software system that integrates the collection, storage, management and analysis of IoT time series data. We use it to store and analyze the collected historical data of monitoring indicators.

Note ⚠️ IoTDB is optional, if not configured, there will be no historical chart data. Support V0.12 - V0.13 version, recommend to use V0.13.* version

If you already have an IoTDB environment, you can skip directly to the YML configuration step.

Install IoTDB via Docker

Refer to the official website installation tutorial

  1. Download and install Docker environment
    Docker tools download refer to Docker official document. After the installation you can check if the Docker version normally output at the terminal.
    $ docker -v
    Docker version 20.10.12, build e91ed57
  2. Install IoTDB via Docker
$ docker run -d -p 6667:6667 -p 31999:31999 -p 8181:8181 \
-v /opt/iotdb/data:/iotdb/data \
--name iotdb \
apache/iotdb:0.13.3-node

-v /opt/iotdb/data:/iotdb/data is local persistent mount of TDengine data directory./iotdb/data should be replaced with the actual local directory. use$ docker ps to check if the database started successfully

  1. Configure the database connection in hertzbeat application.ymlconfiguration file

    Modify hertzbeat/config/application.yml configuration file
    Note⚠️The docker container way need to mount application.yml file locally,while you can use installation package way to unzip and modify hertzbeat/config/application.yml
    Replace warehouse.store.iot-db data source parameters, HOST account and password.

warehouse:
store:
iot-db:
enabled: true
host: 127.0.0.1
rpc-port: 6667
username: root
password: root
# V_O_12 || V_0_13
version: V_0_13
# if iotdb version >= 0.13 use default queryTimeoutInMs = -1; else use default queryTimeoutInMs = 0
query-timeout-in-ms: -1
# default '7776000000'(90days,unit:ms,-1:no-expire)
expire-time: '7776000000'

FAQ

  1. Do both the time series databases IoTDB and TDengine need to be configured? Can they both be used?

    You don't need to configure all of them, you can choose one of them. Use the enable parameter to control whether it is used or not. You can also install and configure neither, which only affects the historical chart data.

  2. The historical chart of the monitoring page is not displayed, and pops up [Unable to provide historical chart data, please configure to rely on the time series database]

    As shown in the pop-up window, the premise of displaying the history chart is to install and configure the dependent services of hertzbeat - IotDB database or TDengine database

  3. The TDengine database is installed and configured, but the page still displays a pop-up [Unable to provide historical chart data, please configure the dependent time series database]

    Please check if the configuration parameters are correct
    Is td-engine enable set to true
    Note⚠️If both hertzbeat and TDengine are started under the same host for docker containers, 127.0.0.1 cannot be used for communication between containers by default, and the host IP is changed
    You can check the startup logs according to the logs directory
