Streaming Telemetry
Overview
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.
Target Users
This guide is intended for:
• Network operations teams monitoring real-time device state and performance
• Automation engineers integrating OcNOS telemetry into collectors and observability platforms
• Platform engineers implementing gNMI-based data streaming
• Support engineers troubleshooting telemetry subscriptions and data flow behavior
• Architects designing scalable, model-driven monitoring solutions
Key Capabilities
This guide enables users to:
• Configure and manage gNMI-based streaming telemetry on OcNOS
• Deploy Dial-In and Dial-Out telemetry subscription models
• Use Stream, Sample, On-Change, Poll, and Once subscription modes
• Select encoding types including Protobuf, JSON, and JSON-IETF
• Work with IPI native and OpenConfig data models
• Configure sensor groups, destination groups, and subscription policies
• Apply wildcard and XPath formatting rules for scalable monitoring
• Secure telemetry sessions using TLS authentication
• Monitor CPU utilization and apply suppression thresholds
• Validate telemetry configuration using operational show commands
• Understand subscription limits and scaling behavior
