The tutorial covers installing InfluxDB 3 Core, loading NASA's C-MAPSS turbofan engine degradation dataset, and writing a Python plugin that runs embedded in the database to estimate Remaining Useful Life (RUL) for each engine. The plugin computes a degradation health index from sensor readings, writes RUL estimates back to the database, and automatically raises maintenance alerts when engines cross a configurable danger threshold. Key concepts include the plugin model (scheduled, data-write, and HTTP-request triggers), using LineBuilder to write points from within a plugin, passing tunable parameters via trigger arguments, and iterating on plugins without recreating triggers. ## Full article daily.dev links to this article rather than hosting it.
