How to use grafana to easily realize OVL data visualization

Preface

This article takes MySQL Taking database as an example, this paper introduces how to use Grafana To achieve OVL Data visualization , There are two ways , One is through OVL Of REST API To realize data visualization , The other is to realize visualization by accessing the data stored in the database . About how to pass through OVL take OPC UA The server data is stored in the database. Please refer to the article 《 Hongke dry cargo | Teach you a few simple steps to achieve OPC UA The server data is stored in the database 》.

      01 work         have        

1. OVL Software

2. MySQL database

3. Grafana Visualization software 、SimpleJson Data source plug-ins and MySQL Data source plug-ins

      02 Operation steps        

adopt REST API Data visualization

1. Enable REST API

open OVL The software “Instance” Interface , Click the Edit button to enter the parameter configuration interface , Check “REST Endpoint Enabled” Options .

2. add to SimpleJson Data source plug-ins

stay Grafana Mid search SimpleJson Data source plug-ins and add .

notes ： The data source plug-in can also be accessed through Grafana CLI Command to install , For related commands, please refer to the following links ：

Grafana CLI | Grafana documentation

3. To configure SimpleJson data source

（1） Configure data source parameters according to requirements , among “HTTP” Options “URL” Medium IP The address and port number are OVL The software IP Address and port number .

（2） After the parameter configuration is completed , Click on “Save & test”, If the configuration is correct , The data source is running .

4. Create a dashboard

（1） Click on “Dashboard” Create a new panel .

（2） Choose to add SimpleJson Data source and required data .

（3） Select the desired chart type .

（4） After the panel parameters are set , Click on “Apply” that will do .

（5） complete OVL Data visualization .

  Realize data visualization by accessing the database  

1. add to MySQL Data source plug-ins

stay Grafana Mid search MySQL Data source plug-ins and add .

2. To configure MySQL data source

（1） To configure MySQL Data source parameters .

（2） After the parameter configuration is completed , Click on “Save & test”, If the configuration is correct , The database connection is successful .

3. Create a dashboard

（1） Click on “Dashboard” Create a new panel .

（2） Choose to add MySQL Data source and insert... As required SQL sentence .

（3） Select the desired chart type .

（4） After the panel parameters are set , Click on “Apply” that will do .

（5） complete OVL Data visualization .

Use Hongke OVL The software can not only OPC UA The server data is stored in the database , And provide REST API, And then pass Grafana Make it easy OPC UA Visualization of server data .
