WebSockets offer a seamless way to visualize real-time IoT data in Grafana, particularly when used with Golioth's IoT development platform. The platform facilitates secure connections to numerous devices, allowing data collection and integration with various systems. Golioth has developed an open-source Grafana plugin that connects to any WebSocket data source using JSON format, enabling automatic updates of Grafana panels as new data arrives without polling. This feature supports both continuous data streams and infrequent alert data, providing real-time monitoring capabilities. The integration process involves adding the WebSocket plugin to Grafana, configuring the WebSocket URL and API key, and setting up a panel to display the incoming data. By using this setup, users can achieve immediate feedback on the health of their devices, making it an essential tool for managing remote IoT hardware fleets. The Golioth platform, which offers a free Dev Tier, allows users to quickly bring devices online, generating data and demonstrating the plugin's capabilities.
