Telemetry Application in Data Center
Updated at Jan 4th 20251 min read
With the explosive growth of global data, data centers are becoming the backbone of modern infrastructure. As their scale and complexity increase, optimizing network performance, diagnosing faults quickly, and ensuring security have become critical challenges. In this environment, network telemetry technology has emerged as a powerful tool to support the efficient operation and management of data centers.
Network Telemetry: The “Eyes” and “Brains” of Modern Data Centers
Network telemetry, as a real-time monitoring and data collection technology, provides a comprehensive view of network status. Compared to traditional network monitoring methods, telemetry not only captures performance metrics such as network traffic, bandwidth, and latency in real time, but also delves into traffic patterns, network topology, and fault data. This offers powerful support for data center managers. With network telemetry, data centers can achieve comprehensive protection, from fault prediction and energy optimization to performance improvement and security defense, ensuring that every critical task is completed more accurately and efficiently.
The following sections will explore the four key areas of network telemetry applications in data centers: performance monitoring, fault detection, resource optimization, and network security. We will analyze how these areas are enhanced by telemetry technology to improve the overall efficiency and reliability of data centers.
Boosting Network Performance with Telemetry
Network performance monitoring is one of the core tasks in data center management, especially in large-scale and complex network environments. Network telemetry collects real-time data on key metrics such as network traffic, bandwidth utilization, latency, packet loss, and throughput. This data provides valuable insights, helping operations teams quickly identify the causes of performance degradation and optimize network performance.
Real-time Traffic Optimization: With telemetry technology, the maintenance team can collect device data at a second-level interval, allowing for timely analysis of anomalies and rapid configuration adjustments to devices. The maintenance platform also receives real-time updates on the adjusted status, ensuring the entire process runs smoothly.

Improving Fault Detection with Telemetry
Network failures can lead to service interruptions or performance degradation, and troubleshooting these issues is often complex. Network telemetry provides detailed data on network traffic, status, and topology, making fault identification and resolution more accurate and efficient.
Microburst Detection: With transient events like microbursts occurring, their duration can be as short as a few microseconds or even less. Telemetry technology can capture this data with high precision (down to nanoseconds), enabling quick fault resolution. Transient network issues are among the most difficult to track, yet they can significantly impact customer experience.
Monitor Every Packet Loss: With detailed telemetry data, combined with network topology and traffic flow information, it becomes possible to quickly pinpoint the node and link where the failure occurred, reducing recovery time. Network telemetry also helps trace historical failures, analyze root causes such as network configuration errors or hardware issues, and prevent the recurrence of similar problems.

Optimizing Data Center Resources with Telemetry
The application of network telemetry in resource optimization and management enables data centers to efficiently allocate, use, and adjust their network, compute, and storage resources. Through real-time monitoring and data analysis, telemetry technology not only improves resource utilization but also reduces operational costs, enhancing the overall efficiency and reliability of the data center.
Linking Network Issues to Applications: For most businesses, applications are a key driver of operations. To ensure application SLAs and for troubleshooting purposes, it's essential to correlate telemetry data with applications. This allows network administrators to identify which applications are causing congestion and who is impacted by service degradation, enabling targeted resource allocation.
Policy-Based Telemetry: Network administrators can define specific telemetry data attributes to monitor based on application policies. By continuously monitoring performance metrics, they can proactively optimize the system to ensure it operates at peak efficiency. This approach helps prevent issues like server overloads, ultimately saving time and resources.

Enhancing Network Security with Telemetry
In data centers, network security is the foundation for ensuring data integrity, confidentiality, and availability. Network telemetry technology provides strong support for network security by helping quickly identify security threats and reduce potential risks.
Custom Alerts: Network administrators can create alerts based on specific events or thresholds. These alerts allow administrators to take critical preventive actions before issues escalate.
Network Health Monitoring: Telemetry technology provides a comprehensive, overall view of the network. This includes statistics on link utilization, buffers, queue depths, and more. Such advanced health monitoring is a fundamental requirement for managing networks today.
