Yes, You Subscribed Correctly. The OPC UA Client Listener Plugin Has Been Released!

The OPC UA Client Listener Plugin is a new input plugin for Telegraf that offers improved performance and data integrity compared to the existing OPC UA Client Reader plugin. The plugin uses subscriptions instead of polling, which allows it to monitor nodes/tags for changes and notify the client of these changes, greatly improving network performance and guaranteeing the integrity of data. This plugin is highly recommended for most use cases but can be used with polling in certain scenarios. A working example config is provided, demonstrating how to set up and subscribe to a robot state using the OPC UA Client Listener Plugin.
