Telemetry involves collecting, transmitting, and analyzing data from remote systems or devices to monitor performance, detect issues, and make informed decisions. It is widely used in industries like software development, IT infrastructure, healthcare, and aviation to track the real-time status of applications, networks, or physical devices.

In the software world, telemetry tools like Prometheus, Grafana, and Datadog provide insights into application performance, system health, and user behavior. Telemetry data can include metrics like CPU usage, memory consumption, response times, and error rates. This information helps organizations detect problems early, optimize resource usage, and improve system reliability by identifying patterns and anomalies.
