By integrating MQTT, Telegraf, and InfluxDB, you’ll construct a robust, fully-functioning data pipeline capable of efficiently centralizing real-time telemetry.

InfluxDB is a time-series database platform for collecting, storing, and analyzing time-stamped data, offering tools for monitoring, observability, and IoT applications. From this resource users can learn about time-series data modeling, querying, and visualization to monitor and analyze their systems' performance and behavior in real-time.

InfluxData

A step-by-step guide to building an MQTT data pipeline that centralizes IoT/sensor telemetry into InfluxDB 3. Covers installing and configuring Eclipse Mosquitto as the MQTT broker, setting up publishing clients, installing InfluxDB 3 Core, and configuring Telegraf as the bridge between MQTT and InfluxDB. Includes topic parsing and pivot processing in Telegraf for a clean data model, plus an overview of why InfluxDB's time-series optimizations (sub-10ms queries, gap-fill functions, retention policies) make it well-suited for high-volume MQTT workloads.
