A big part of this setup is about the provisioning of the edge stack with all you need to run a modern historian.
6 Docker containers are used:
- OPC-UA Server
- InfluxDB
- Telegraf
- Grafana
- Portainer
- Traefik
Here is a diagram to show the architecture:
Several configurations are applied during the provisioning process in order to automate and simplify the setup. Below is a quick summary of what you get out of the box:
- OPC-UA Server:
- A Pump object added to the OPC-UA server namespace for the scope of the demo scenario. Read more here on the setup of the OPC-UA server.
- InfluxDB v2:
- tokens for telegraf and Grafana created
- bucket created
- task to calculate prussures differences
- Telegraf:
- configuration to read data from the OPC UA Server
- configuration to write data into InfluxDB's bucket
- Grafana:
- datasource configuraion
- demo dashboard
- Trefik:
- Setup Traefik as reverse proxy and load balancer for Portainer and Grafana
InfluxDB2's generated tokens are stored on output/tokens.txt file.
Below is a screenshot for the provisioned dashboard:
In order to get access to the services please, refer to the below table:
| Service | URL | Username | Password |
|---|---|---|---|
| InfluxDB v2 | http://localhost:8086 | demouser | demopassword |
| Grafana | https://localhost:6443/grafana | demouser | demopassword |
| Portainer | https://localhost:6443/portainer/#!home | admin | |
| Traefik | https://localhost:6443/dashboard/#/ | admin | demopassword |
To get access to the OPC UA Server, you can use any OPC UA client, e.g. Prosys
As url, use the following opc.tcp://localhost:4334/UA/DemoOPCUAServer
NOTE: In case of cloud deployment, ensure to replace localhost with the public IP address of your droplet.
The project is available to be provisioned for both Unix-based and Windows users. Follow the relative guides below to get started.
