Use Time Series Database InfluxDB to Store Metrics Data (Optional)

Apache 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)

It is recommended to use VictoriaMetrics as metrics storage.

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. Note⚠️ Need InfluxDB 1.x Version.

1. Use HuaweiCloud GaussDB For Influx

Use HuaweiCloud GaussDB For Influx

Get the GaussDB For Influx service url, username and password config.

⚠️Note GaussDB For Influx enable SSL default, the service url should use https:

2. Install TDengine via Docker

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.

   shellCopy

   $ docker -v
   Docker version 20.10.12, build e91ed57
   

2. Install InfluxDB with Docker

   shellCopy

   $ docker run -p 8086:8086 \
   -v /opt/influxdb:/var/lib/influxdb \
   influxdb:1.8
   

   -v /opt/influxdb:/var/lib/influxdb is local persistent mount of InfluxDB data directory. /opt/influxdb 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

1. Configure HertzBeat's configuration 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.influxdb data source parameters, URL account and password.

   yamlCopy

   warehouse:
      store:
         # disable jpa
         jpa:
            enabled: false
         # enable influxdb
         influxdb:
            enabled: true
            server-url: http://localhost:8086
            username: root
            password: root
            expire-time: '30d'
            replication: 1
   

2. Restart HertzBeat

FAQ

1. Do both the time series databases InfluxDB, 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.
