Deadman Alerts with the Python Processing Engine

This tutorial demonstrates how to use the Python Processing Engine with InfluxDB 3 Core and Enterprise to build a deadman check and alert, which notifies users immediately when expected data stops arriving. The process involves creating an InfluxDB 3 instance, setting up a Slack webhook URL, writing data to the database, creating a trigger, and enabling the deadman check plugin. If no new data is received within a configurable time threshold, the plugin sends a notification to the designated Slack channel or HTTP endpoint. This tutorial provides a flexible way to monitor data pipeline durability in real-time and demonstrates how to build custom plugins using Python.
