About telemetry data

Let's start with the question: What is telemetry data? The term telemetry, refers to the transmission of measured values from a sensor to a spatially separated location.

At this receiving point, the measured values are either only recorded and collected, or transferred directly to an evaluation process.

The acquisition of telemetry data is often supplemented by a path of action to the detecting sensor, so as to be able to respond to the delivered measured values with suitable actions. This return path is called remote control.

Let's move on to the area of monitoring. Here, we could also talk about a telemetry process. For example, a network device can assume the role of a sensor and constantly transmit data about the state of the connection, latency, and much more.

Although we can speak of telemetry, I would like to introduce a second term that is more common when using monitoring solutions: metrics.
