Introduction

Juniper Apstra provides robust automation for managing data center switching fabrics. Apstra’s Intent-Based Networking (IBN) helps create, deploy, operate, and validate networks.

Apstra performs validation to ensure:

• User-supplied inputs are valid.

• User inputs align with network constraints.

• Expected telemetry outputs are correct in a stable network.

• No discrepancies exist between expected and actual telemetry.

After you deploy your network, Apstra collects and validates telemetry data from managed devices. Apstra aggregates and cross-checks the collected telemetry against the intended state of telemetry types, including interfaces, LLDP, and BGP. Intent-Based Analytics (IBA) delivers accurate data for efficient operations and informed decisions making.

Starting with Release 4.2.0, Apstra introduces its Custom Telemetry Collection. This collection lets you quickly configure Apstra to gather new telemetry data from managed devices. Apstra then uses that data in IBA probes to automate knowledge extraction through analysis and visualization.

This document provides IBA fundamentals and explains how to create a custom telemetry service. You will also learn how to build an IBA probe for data visualization and analysis. This guide includes a use case that demonstrates how to:

• Define a telemetry service for power metrics collection from managed devices.

• Create an IBA probe to monitor, detect, and visualize power consumption.

• Store anomaly history in a time-series database.
