Companies can analyze this data to assess individual and team productivity levels, identify best practices, and find areas where they might need additional support training. Employee behavior telemetry can even help spot potential security risks associated with insider threats or policy violations. Companies can detect and quickly react to unusual activities, such as unauthorized access attempts or data exfiltration.

User Telemetry: Understanding User Behavior

User telemetry data gives companies a deeper understanding of how users interact with systems, applications, and services. This includes data points such as user actions, preferences, and usage patterns. You can use this information to optimize user experiences, streamline workflows, and develop targeted training programs to improve user adoption and proficiency.

Application Telemetry: Monitoring Application Performance

Application telemetry involves monitoring application performance to ensure that software operates efficiently and meets user expectations. It collects data on important aspects like how fast the system responds, how often errors occur, how long it is up and running, and how much CPU, memory, and disk space it uses.

By examining these metrics, IT teams can pinpoint where performance lags, predict potential system failures, and gauge the effects of updates or new settings for modern applications.

Network Telemetry: Analyzing Network Infrastructure

Network telemetry analyzes and strengthens network infrastructure to ensure it remains robust and secure. It gathers data on traffic flow, bandwidth usage, how fast data travels within the network (latency), and how much data fails to reach its destination (packet loss). It also tracks security issues, such as unauthorized access attempts and malware detections.

This information helps network administrators improve network monitoring performance by spotting areas where data transmission is congested, managing bandwidth distribution, and setting priorities for different types of network traffic.

Database Telemetry: Identifying and Resolving Database Errors

Database telemetry, a specific type of telemetry data, is essential for effectively identifying and resolving database errors. It tracks various metrics, such as query execution times, error rates, lock durations, and resource usage (CPU, memory, I/O).

This data helps database administrators (DBAs) identify and address problematic queries that might slow down or crash the system. Analyzing these key metrics also helps DBAs enhance query performance, adjust resource allocation, and implement indexing strategies to improve database access reliability.

Challenges in Telemetry Data Collection

We’ve covered the advantages of telemetry data and how it can improve a company’s overall cybersecurity posture. However, collecting telemetry data doesn’t come without its challenges.

Below, we’ll check out the critical challenges in the collection of telemetry data:

Managing the Volume of Telemetry Data

Managing the large volume of telemetry data is challenging due to the massive amounts of data generated in modern IT environments. As systems and networks become more complex, the data collected increases exponentially, which can overwhelm traditional data processing and storage solutions.

Companies need scalable storage solutions and robust data management strategies to handle this. Data compression, real-time data processing, and selective data collection are essential to reduce the strain on storage systems. 

Some companies even use advanced data analytics, and machine learning helps filter out unnecessary data and extract valuable insights from large datasets.
