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. For example, they were used for monitoring and controlling processes in sectors such as oil, gas, and manufacturing.
Thanks to constant advances in wireless communication and data transmission and processing, telemetry systems have become increasingly sophisticated. The emergence of technologies like computers, the internet, and IoT devices means we now live in an interconnected world where telemetry is ubiquitous.
Today, collecting, processing, and analyzing telemetry data is vital across a wide range of fields and industries, including healthcare, manufacturing, automotive, transportation, environmental monitoring, meteorology, space exploration, agriculture, software development, transportation, and infrastructure management. Organizations everywhere rely on telemetry data to extract actionable insights, make data-driven decisions, and improve operational efficiency.
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?
The process of working with telemetry data involves a few key steps:
- Collecting and transmitting data
- Processing and storing data
- Analyzing data
1. Collecting and transmitting telemetry data
Collecting and transmitting telemetry data involves using sensors to monitor an environment, system, or location of interest. It’s important to note that sensors can take different forms. They can be physical devices (for example, a temperature or a pressure sensor). Or they can be software-based agents and modules, such as a network traffic sensor, or a telemetry service embedded in an operating system.
These sensors are configured to collect data generated by the environment or system they are monitoring. Depending on the use case, this can include measurements such as temperature, pressure, humidity, voltage, network traffic, clickstream data, etc. Telemetry data may be collected at regular intervals or in real time.
Once captured by sensors, telemetry data is then transmitted to a central or remote system for storage and processing. The transmission can be done using various communication technologies. Examples include wired connections (like Ethernet), wireless technologies (such as infrared systems, Bluetooth, and radio), and cellular and computer networks.
2. Processing and storing telemetry data
After telemetry data has been transmitted to the central system, it needs to be processed. This is necessary because most telemetry data transferred by sensors is raw, unstructured, and hard to analyze.
Processing telemetry data might involve steps like:
- Data cleaning - removing or correcting inconsistencies, filling missing values, and handling anomalies to ensure data quality.
- Data transformation - converting data formats, normalizing or standardizing values, or applying mathematical or statistical transformations.
- Data integration - combining data from different sources or sensors to create a unified dataset.
Once processed, telemetry data is structured, which makes it easier to analyze.
Processing (transforming and merging) unstructured telemetry information, so it becomes structured data, which is easier to store and analyze.
Another thing to ponder is where to store the data. Telemetry data can be kept in databases, data lakes, data warehouses, or cloud storage solutions. Storing telemetry data enables organizations to analyze past data and identify patterns, trends, or anomalies that can provide insights into system performance, user behavior, or operational efficiency.
Whether you process telemetry data first and then store it or vice-versa depends on the specifics of your use case. The "store first, process later" approach is commonly used in batch processing scenarios, where data is collected and stored in raw form without immediate processing. Collected data is then processed later, at scheduled intervals.
On the other hand, the "process first, store later" approach is often used in real-time processing scenarios. For example, if you’re monitoring critical systems, telemetry data needs to be processed as soon as it’s ingested so that you can make in-the-moment decisions based on the most recent information available. Processed data can then be stored for future reference and further analysis.
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.
Data visualization techniques are frequently used to present telemetry data in a visually appealing format. Charts, graphs, dashboards, and plots communicate complex data relationships and data-driven insights in a way that is easy to understand and reason about.
For example, the image below shows a dashboard that displays telemetry data collected from a mobile device, together with the timestamp of any crash (accident) event.
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. For example, telemetry data empowers us to optimize the performance of systems, improve user experiences, streamline processes, enhance security measures, and even drive business and revenue growth.
Real-time vs. historical telemetry data
Collecting and batch processing data was the standard way of managing telemetry for a long time. Batch processing was (and continues to be) a viable option for scenarios where immediate analysis is not required. For example, if you wanted to identify patterns in energy consumption at a factory, you would collect historical data, store it, and analyze it in large batches.
However, for many telemetry use cases, batch processing is too slow. For instance, if your goal is to detect equipment malfunctions or potential failures as soon as they happen, you need the ability to collect, process, and analyze telemetry data in real time. It’s the only way you can perform timely maintenance interventions and reduce downtime.
The emergence of data streaming and stream processing technologies in the past decade has enabled more companies to analyze telemetry data in real time.
Not only do streaming and stream processing technologies allow you to process and analyze data in real time, but they offer additional benefits, such as:
- Reduced data storage costs. Stream processing technologies enable you to process data “in-memory”, as soon as it becomes available. This way, you can reduce your reliance on data storage and decrease compute costs. In comparison, with batch processing, you frequently have to store unstructured telemetry information you’ve gathered from sources, then process it, and then store it again, as structured data.
- Scalability and reliability. Take, for example, Apache Kafka, a distributed streaming platform that’s widely used for building real-time telemetry data pipelines and streaming applications. Kafka is designed to handle high-throughput, fault-tolerant, and scalable data streams, making it ideal for processing large volumes of high-frequency data in real time.
By using data streaming and stream processing technologies when dealing with telemetry data, organizations can gain real-time insights, enhance monitoring capabilities and situational awareness, and enable faster and more proactive decision-making based on up-to-date information.
That’s not to say that batch processing is outdated or obsolete — it’s a perfectly valid option if there’s no urgency to analyze data as soon as you collect it. Leveraging a streaming architecture means you can actually benefit from both real-time stream processing and batch processing. For example, you could use a streaming solution like Kafka or Amazon Kinesis to ingest streams of telemetry data and process them on the fly, in real time. Processed data can then be consumed immediately by downstream systems, apps, and ML models to extract real-time insights.
In addition, tools like Kafka and Amazon Kinesis offer connectors (integrations) that allow you to move streams of telemetry data (processed or raw) to various databases and data warehouses for long-term storage and batch analytics.
To learn more about the example depicted above and how you can use a streaming architecture for both stream processing and batch processing, read this article.
