What is Telemetry?
Telemetry is a technology that enables the automatic measurement and transmission of data from remote or inaccessible sources to an IT system. The term originates from the Greek words "tele," meaning remote, and "metron," meaning measure. In the context of software engineering and computing, telemetry are solutions that collect, process, and deliver all types of data from various applications, systems, and sensors, enabling functions such as IoT remote monitoring & control, predictive maintenance, and complex event processing.
How does Telemetry work?
Telemetry works by installing sensors or meters on the target system that need monitoring or tracking. Sensors capture and measure data ranging from system performance statistics, usage patterns, operational anomalies, or any other significant parameters. Once the data is collected, it's converted into readable formats before being transmitted over networks and forged into data/contol dashboards and analytics reports.
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.
