# OPC UA Datasource plugin for Grafana
## STATUS
> [!CAUTION]
> This plugin is now deprecated. This deprecation means that this plugin won't receive any feature updates or bug fixes except critical security fixes. After 6 months (End of June 2024), the plugin will reach EOL and there won't be any fixes afterwards. Existing installations of the plugin will continue to work. Reach out to [Grafana Community Forum](https://community.grafana.com/) if you need any further assistance on this plugin.
## Introduction
Utilizing the datasource plugin framework, this projects allows you to access data from OPC UA servers directly from Grafana.
## What works
* Browsing and adding multiple servers
* Authenticated connection with certificate or no security
* Graphical query editor
* Data Access (DA)
* Historical Access (HA / HDA)
* Alarms & Conditions (AC / AE)
## What needs to be implemented
* OPCUA DA Subscriptions: These are the ones where you will not need to hit the refresh button. If you have subscribed to a data point at 500ms, you will get an unsolicited update every 500ms.
* Password authentication
* Two-way communication with the OPC UA server (currently read only)
## Description and Architecture
This plugin uses GRPC and a C# backend to communicate with Grafana directly. See `pkg/dotnet` directory for the backend component
## Building
* `yarn install` to install dependencies
* `yarn build | yarn dev` to build the plugin
* `make build` to build the backend component
Restart Grafana and you should have the datasource installed.

## Q&A
Q: **Can it read OPC Classic DA/HDA/AE?**
A: Yes, provided use use the OPC Foundations COMIOP wrapper, which you can find [here](https://github.com/OPCFoundation/UA-.NETStandard). You will need to configure IOP to wrap your OPC COM server. Tested against Matrikon OPC Desktop Historian and Matrikon OPC Simulation Server.
