MQTT Topic and Payload Parsing with Telegraf

This post discusses Telegraf as a consumer of MQTT messages in the context of writing them to InfluxDB. It covers topic parsing and payload parsing, which allow users to shape incoming data for compatibility with their destination data store. Topic parsing enables users to specify which portions of an MQTT topic they want to bring in as measurement, tags, or fields. Payload parsing allows users to parse the JSON payloads that are commonly used in this context. The post provides examples and configurations for both topic and payload parsing.
