How does the use of telemetry benefit network troubleshooting?

Device discovery, security, and statefulness are generally not the primary benefits of telemetry itself, nor does telemetry primarily use a "pull model"; streaming telemetry is known for its "push model" for data collection.

While telemetry data can inform network policy modifications, its direct benefit is providing data for analysis, not directly increasing fast rerouting or modifying policy itself.

Telemetry is designed to provide *relevant* and *necessary* data, and a key benefit is reducing the burden on clients by providing this data proactively, rather than providing "unnecessary data" when requested.

Network telemetry, particularly streaming telemetry, uses a push model to automatically send granular, low-latency data to collectors. This reduces the need for clients to constantly poll devices (pull model), thereby lowering client overhead and providing near real-time insights crucial for efficient troubleshooting and proactive issue detection.
