id: iotdb-init title: Use Time Series Database IoTDB to Store Metrics Data (Optional) sidebar_label: Use IoTDB Store Metrics HertzBeat's historical data storage relies on the time series database, you can choose one of them to install and initialize, or not to install (note but it is strongly recommended to configure in the production environment) We recommend VictoriaMetrics for long term support. Apache IoTDB is a software system that integrates the collection, storage, management and analysis of time series data of the Internet of Things. We use it to store and analyze the historical data of monitoring metrics collected. Support V0.13+ version and V1.0.+ version. Note Time series database is optional, but production environment configuration is strongly recommended to provide more complete historical chart functions and high performance If you do not configure a time series database, only the last hour of historical data is retained. If you already have an IoTDB environment, you can skip directly to the YML configuration step. Refer to the official website Download and install Docker environment Docker tools download refer to . After the installation you can check if the Docker version normally output at the terminal. ``` $ docker -v Docker version 20.10.12, build e91ed57 ``` Install IoTDB via Docker ```shell $ 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 IotDB data directory.`/iotdb/data` should be replaced with the actual local directory. use```$ docker ps``` to check if the database started successfully Configure the database connection in hertzbeat `application.yml`configuration file Modify `hertzbeat/config/application.yml` configuration file NoteThe 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` Config the `warehouse.store.jpa.enabled` `false`. Replace `warehouse.store.iot-db` data source parameters, HOST account and password. ``` warehouse: store: jpa: enabled: false iot-db: enabled: true host: 127.0.0.1 rpc-port: 6667 username: root password: root version: V013 query-timeout-in-ms: -1 expire-time: '7776000000' ``` Restart HertzBeat 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. 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 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 NoteIf 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
