Telemetry data explained
Gain a thorough understanding of telemetry data and how it works, learn about its benefits, challenges, and applications across different industries, and discover technologies you can use to operationalize telemetry.
What is telemetry data?
Telemetry refers to measuring, collecting, and transmitting data from remote or inaccessible devices, systems, or environments to another remote location. Telemetry typically involves using sensors or monitoring equipment to automatically measure and gather data, which is then sent to a system in a different place for processing, storage, and analysis.
Why does telemetry data matter?
Telemetry data is akin to a patient’s vital signs. Doctors rely on metrics like heart rate, blood pressure, body temperature, and oxygen levels to diagnose and monitor their patients, detect anomalies, and quickly react if they are in danger. Similarly, organizations depend on telemetry data to monitor and gain insights into the health of their systems and processes, detect and diagnose issues, optimize performance, and make informed decisions.
A brief history of telemetry
Telemetry is by no means a new concept. Some trace its origins back to the Steam Age, when the mercury pressure gauge was invented, allowing engine conductors to monitor the pressure in Watt steam engines from a near distance. In the early 20th century, telemetry systems were first employed to monitor electric power distribution. Throughout the latter half of the 20th century, telemetry systems evolved further and found applications in other industries.
Telemetry data types
When handling telemetry, software developers and data teams usually have to deal with the following types of data:
- Time series sensor data, such as temperature readings collected every minute from a network of IoT sensors deployed in a smart building.
- Audio and video data collected, for example, from surveillance cameras.
- Light detection and ranging (LiDAR) data providing detailed spatial information about objects or the environment.
- Clickstream data that records user interactions, behaviors, clicks, and navigation in web and mobile apps.
- Event data, trace data, metrics, and logs, which are commonly used for software and network observability purposes.
- Business logic data. As an example, in the case of an e-commerce platform, this may include order placements, payment verifications, inventory updates, and shipping notifications.
- Application layer data like application response times and latency measurements.
- Infrastructure layer data such as network bandwidth usage, packet loss, and CPU usage metrics.
How does telemetry work?
1. Collecting and transmitting telemetry data
Collecting and transmitting telemetry data involves using sensors to monitor an environment, system, or location of interest. These sensors are configured to collect data generated by the environment or system they are monitoring. Once captured by sensors, telemetry data is then transmitted to a central or remote system for storage and processing.
2. Processing and storing telemetry data
After telemetry data has been transmitted to the central system, it needs to be processed. Processing telemetry data might involve steps like:
- Data cleaning
- Data transformation
- Data integration Once processed, telemetry data is structured, which makes it easier to analyze.
3. Analyzing telemetry data
Analyzing telemetry involves exploring and interpreting processed data to gain insights, detect anomalies, and identify patterns and trends. Typical data analysis tasks include statistical analysis, correlation analysis, data mining, machine learning (ML), time series analysis, and predictive modeling.
How to use telemetry data?
The primary purpose of collecting, processing, and analyzing telemetry data is to obtain actionable insights. Telemetry data can be acted upon to achieve specific goals or tackle specific challenges.
Real-time vs. historical telemetry data
Collecting and batch processing data was the standard way of managing telemetry for a long time. However, for many telemetry use cases, batch processing is too slow.
The emergence of data streaming and stream processing technologies in the past decade has enabled more companies to analyze telemetry data in real time.
