Telemetry on IOS-XE in 3 Easy Steps

Streaming telemetry is considered more modern compared to SNMP. It offers real-time data collection, scalability, flexibility, and support for diverse data types, making it better suited for modern network management requirements. Additionally, streaming telemetry aligns well with the growing demand for real-time analytics, automation, and dynamic network infrastructure.
Advantages of Streaming Telemetry:

🚨Real-time Data: Provides real-time insights into network performance and health, allowing for faster detection and resolution of issues.
🚨Granular Data: Offers fine-grained data collection, enabling more detailed analysis and troubleshooting compared to SNMP polling.
🚨Scalability: Scales more effectively to handle large volumes of data from distributed network devices without overwhelming network bandwidth.
🚨Efficiency: Utilizes efficient data transmission methods such as Restconf or gRPC, reducing network overhead compared to SNMP polling.
🚨Extensibility: Enables easy integration with modern monitoring and analytics platforms, supporting advanced analytics, machine learning, and automation.
🚨Polling-Based: SNMP relies on periodic polling of network devices, which can result in delays in data collection and potentially miss transient issues or spikes in traffic.
🚨Bandwidth Consumption: SNMP polling can consume significant bandwidth, especially in large-scale deployments or when monitoring numerous devices at high frequencies.
🚨Limited Data Types: SNMP primarily supports integers and string data, lacking the flexibility to handle richer data types or serialized structured data formats.
🚨Scalability Challenges: SNMP may struggle to scale effectively in dynamic or large-scale network environments, leading to performance bottlenecks or management overhead.
🚨Configuration Complexity: SNMP management involves configuring and managing complex MIBs, which can be challenging to maintain and troubleshoot, especially in heterogeneous network environments.

The benefits are endless but overall, streaming telemetry offers superior capabilities for real-time monitoring, scalability, and flexibility compared to SNMP, making it better suited for modern network management needs.
