What is Telemetry?

Telemetry is a technology that automates the measurement, collection, and transmission of data from remote, inaccessible, or distributed sources to centralized IT systems. It supports analysis, storage, and decision-making processes. Derived from the Greek "tele" (remote) and "metron" (measure), telemetry is essential where manual data collection is impractical. Telemetry systems capture data from industrial sensors, environmental monitors, industrial & medical devices, and software applications. Metrics include data points like temperature, pressure, and system performance. Data is transmitted securely using communication protocols like MQTT or HTTP/HTTPS, then processed by analytics platforms. Telemetry enables real-time insights, predictive maintenance, and improved efficiency in IoT, eCommerce, healthcare, and smart cities.

Telemetry data can be a useful source for troubleshooting, tuning systems for optimal performance, understanding how users interact with a system, and predicting future trends or malfunctions. The value it delivers ties directly to the richness of the collected data, the data analytics process's effectiveness, and the data delivery's timeliness.

Types of telemetry solutions

Telemetry can be categorized based on the data it collects and the systems it monitors.

Application telemetry tracks software performance, errors, and user interactions.

Network telemetry monitors data flow, bandwidth, and security across networks.

Device telemetry gathers information from hardware like IoT devices or sensors, including temperature, pressure, or motion.

Medical telemetry focuses on patient health data, such as heart rate or oxygen levels, for remote monitoring.

Environmental telemetry measures conditions like weather, air quality, or seismic activity.
