About This Guide
The OcNOS Streaming Telemetry Guide provides a comprehensive reference for monitoring operational state and performance data from OcNOS devices using model-driven telemetry. It explains how OcNOS streams structured data to external collectors using gNMI over gRPC and how telemetry integrates with native IPI and OpenConfig data models.
This guide covers dial-in and dial-out subscription models, streaming modes, encoding types, sensor path configuration, TLS security, CPU monitoring, and telemetry scale considerations. It also describes wildcard support, XPath formatting rules, subscription limits, and operational verification commands.
The guide enables users to understand how telemetry functions in OcNOS and how to configure, validate, and troubleshoot streaming telemetry deployments across service provider and data center environments.
