New and Updated Features

This section describes the new and updated features released in Juniper Data Center Assurance.

Assurance

Predictive Analytics for Optical Interface Health

DC Assurance enables you to prevent potential failures in the optical interfaces of the network devices by utilizing the insights provided by an ML-based mechanism to predict optical health. Identifying potential issues early enables you to take corrective actions in advance, thereby preventing link outages and ensuring continuous network reliability.

The ML models use the data received from the Optical Transceivers probe in Apstra to predict future metrics and recognize outliers that might occur in a 15-day period for the following parameters:

  • Received optical power (RX power)

  • Transmitted optical power (TX power)

  • Laser bias current

  • Voltage

  • Temperature

The Predictive Analytics feature identifies the services and clients that would be impacted by the forecasted outliers. It also displays the historical, current, and future metrics for specific interfaces in the topology.

Note:

Predictive Analytics for Optical Interface Health requires your Apstra Data Center Director instance to be running Apstra version 6.1 or higher.

Monitoring and Troubleshooting

View External Routers in the Data Center Network in Topology Views

You can view the external routers connected to the Apstra-managed data centers in the topology views on the App Aware, the Impact Analysis, and the Dashboard pages.

The external routers are external generic systems that can be connected to an Apstra-managed data center network. These systems provide connectivity between two or more data centers as Data Center Interconnect (DCI) connections to share data and resources. DC Assurance supports external routers connected to a border leaf of the data center network architecture and provides information about the health and status of the external router.

Service Level Expectations

Support for Service Health SLE

DC Assurance enables you to monitor the health of the services running in the data center network. The Service Health SLE provides information about the overall service performance impact due to system health and link health related anomalies.

An administrator can use this information to proactively respond to network issues that impact end user experience.

Sustainability

As networks expand to handle increasing bandwidth needs, energy consumption rises proportionally, leading to higher operational costs and a greater carbon footprint. To address this issue, organizations set goals to optimize power usage and reduce emissions. Real-time access to power and emission data, along with actionable recommendations, supports the sustainability objectives of organizations.

Data Center Assurance provides a sustainability dashboard that helps administrators monitor and optimize energy consumption and carbon emission.

To view insights in the sustainability dashboards in Juniper Data Center Assurance, ensure the following:

  • Sustainability feature must be enabled for your organization. To enable the feature for your organization, contact your designated Juniper Networks representative. After the feature is enabled, it can take up to a day for energy data to appear on the dashboards.

  • The Apstra Edge is onboarded to Juniper Data Center Assurance. You can verify the Edge status from the DC Edges page. See, Adopt Juniper Apstra Edge.

  • Verify that devices and software versions meet the supported requirements for energy insights. See, Energy Insights: Supported Platforms and Software Versions.

  • Sustainability settings, such as average power cost, carbon intensity, and port utilization thresholds are correctly configured. These parameters help generate accurate sustainability insights across the organization and its sites.

    See, Configure Sustainability Settings for the Organization, Configure Port Threshold for the Organization.

The sustainability dashboard provides the following information:

  • Actionable insights for power conservation and greenhouse gas emission.
  • Real-time visibility into device power usage, underutilized resources, and idle states—enabling safe shutdowns without impacting network traffic.
  • AI-generated forecasts for energy requirements and associated costs, as well as GHG emissions.
  • Faster troubleshooting of power-related anomalies by identifying problematic devices.

The following sections describe the key sustainability features that Data Center Assurance provides:

Actionable Energy Insights for the Organization

Data Center Assurance provides a dashboard for monitoring sustainability insights at the organization level. From the dashboard, you can track the following information:

  • Current real-time power consumption

  • Aggregated power consumption for the past hour

  • Greenhouse gas emission for the past hour

  • Cost of the power consumed for the past hour

  • Sites ranked in the descending order of energy consumption

These insights help optimize power consumption and track carbon emission trends, thereby contributing to the organization's sustainability and SBTi goals.

[See, View Sustainability Insights for an Organization.]

Actionable Energy Insights for Sites

Use the Site-Level Energy Dashboard to gain comprehensive visibility into a site's energy profile.

Use the dashboard to:

  • Monitor current and historical site-level energy metrics, including power usage, energy consumption, GHG emissions, and power cost.
  • Analyze site-level energy efficiency trends using power-versus-throughput visualizations to understand how energy usage correlates with network load over time.
  • Visualize the site’s network fabric and compare devices across energy, emission, and thermal metrics.
  • Identify top devices in the site across key energy dimensions such as energy consumption, throughput, fan speed, and temperature deviation and evaluate their contribution to overall site energy usage.
  • Review the site’s annual energy report to access actual and historical energy data and AI-generated energy forecasts and use it to support your organization’s SBTi planning and sustainability reporting.

[See, View Sustainability Insights for a Site.]

Actionable Energy Insights for Devices

The Device-Level Energy Dashboard provides granular visibility into the energy usage of individual network devices in your data center. The dashboard includes four dedicated views to help you monitor device behavior, detect inefficiencies, and improve device-level power utilization.

  • Use the Overview tab to view a device’s real time and historical power usage, energy consumption, GHG emissions, power cost, and historical power and throughput trends. Review per port peak and off-peak traffic patterns to identify idle or underutilized ports.
  • Use the Power Supply tab to monitor a device's power module health, redundancy, input-feed status, and device's power capacity and utilization.
  • Use the Thermal Profile tab to track a device’s temperature trends, fan activity, top thermal sensors by deviation, and power trend impact on cooling.
  • Use the Recommendation tab to review data-driven, device-specific energy optimization suggestions that highlight opportunities to reduce idle power draw and improve sustainability.

Configure Port Utilization Threshold

You can configure percentage-based utilization thresholds to classify device ports as Low, Medium, or High utilization. Thresholds apply globally by default, and can be overridden by configuring port threshold at the site level for specific sites. The system provides default thresholds inferred from historical traffic and usage patterns, which administrators can customize as needed. The threshold values are used to render per-port traffic heatmaps and to generate accurate port-level energy optimization recommendations.

To configure port threshold at the organization-level, Organization > Settings > Port Traffic Threshold.

[See, Configure Port Threshold for the Organization.]

To configure port threshold at the site-level, Organization > Site Configuration > Port Threshold.

[See, Configure Port Threshold for the Site.]

Recommendations to Optimize Energy Consumption

Juniper Data Center Assurance provides port-level energy optimization recommendations for network devices. These recommendations help conserve energy, reduce carbon emissions, and save on operational costs. The following two energy optimization recommendations are available in the current release.

  • Optimize low-traffic ports based on historical traffic patterns—The Low-Traffic Port Optimization recommendation identifies ports with consistently low utilization based on historical traffic patterns. It provides actionable guidance, including observed low-traffic windows and relevant configlet-based actions to safely disable ports and reduce idle power consumption.

    [See, Optimize Low Traffic Ports Based on Historical Traffic Patterns.]

  • Optimize energy consumption by shutting down unused ports—The Device Port Power Optimization recommendation identifies unused ports on a device based on operational state and traffic patterns. It provides actionable guidance, including associated benefits and risks, along with relevant configlet-based actions, to safely disable ports and reduce idle power consumption.
