OPC UA Time Series Hub

Overview

The OPC UA Time Series Hub is a personal project designed to integrate various technologies into a cohesive system for monitoring and storing time series data from OPC UA servers. This project uses InfluxDB2 and Telegraf for data storage and collection, with a focus on the OPC UA protocol for industrial automation and IoT applications. The main feature of this project is the opc-ua-time-series-hub-web, a web interface that allows users to browse the OPC UA hierarchy and select tags for storage in InfluxDB.

Components

  • InfluxDB V2: Time series database used for storing the collected data.
  • Telegraf: An agent for collecting, processing, aggregating, and writing metrics.
  • OPC UA Server (mcr.microsoft.com/iotedge/opc-plc): Simulates an OPC UA server generating random data.
  • MySQL Database: Stores user settings and configurations.
  • OPC UA Time Series Hub API: Custom service that interfaces with the OPC UA server and Telegraf.
  • OPC UA Time Series Hub Web: The web interface for interacting with the OPC UA server's data hierarchy.

Getting Started

To get started with the OPC UA Time Series Hub, clone this repository to your local machine and ensure Docker and Docker Compose are installed.

git clone https://github.com/brentoncollins/opc-ua-time-series-hub.git
cd opc-ua-time-series-hub/deploy
docker-compose up -d

  1. Navigate to http://localhost:3000 in your web browser to access the web interface, add OPC UA Tags by expanding the OPC UA Hierarchy and selecting the checkboxes, click Update Telegraf Config

    Note: If you see Failed to fetch nodes. Please try again later. The OPC Server is still starting, give it a minute and refresh the page.

  2. Navigate to http://localhost:8086 in your web browser to access the InfluxDB2 interface with default User: root Password: password, which can be changed in the docker compose file.

Have a look through the docker compose file to change the configuration for the OPC Server, see the documentation at mcr.microsoft.com/iotedge/opc-plc to see the available configuration options. This is not secure, and should not be used in a production environment.
