View Sustainability Insights for a Device

In data center networks, traffic patterns can fluctuate significantly depending on workload. However, most network devices typically draw a near-constant level of power, even during low traffic windows. Always-on components, such as control planes, PSUs, transceivers, PHY devices, and cooling systems, contribute to this idle power draw and lead to substantial energy wastage during low utilization periods. To optimize energy usage, you need visibility at the individual device level.

The Device-Level Energy dashboard provides you comprehensive energy observability at the individual device level. You gain granular visibility into the device's energy consumption, how efficiently it operates under different traffic conditions, and how you can optimize power usage without impacting device performance.

Use the dashboard to monitor power usage, analyze power-to-traffic proportionality, review per-port activity, monitor thermal performance, and identify opportunities to reduce idle power draw without impacting device performance. You also receive intelligent, data-driven recommendations to guide energy optimization efforts across your data center.

The device-level energy insights are organized into four tabs:

Table 1: Top Tasks by Tab

Tab	Top Tasks
Overview	Monitor a device's power usage, energy consumption, GHG emission, power cost, and track historical trends Analyze a device's power vs throughput behavior Review per port peak and off-peak traffic patterns Correlate port activity with power usage
Power Supply	Diagnose power supply efficiency, redundancy, and input-feed issues. Verify device power capacity and utilization Check power module status Review detailed power module metrics
Thermal Profile	Proactively manage thermal performance. Monitor a device's temperature and fan speed trends Analyze the device power trend Review a device's top sensors by temperature deviation Inspect fan status per tray
Recommendation	Review energy optimization recommendations that can help optimize the device's energy consumption and improve sustainability.

Each tab provides key energy metrics, time-series trends, and actionable insights based on device telemetry.

Attention:

All values displayed on the dashboard are estimations based on the telemetry streamed every 5 to 15 minutes from the device. These values are intended for monitoring and analysis purposes and may not always reflect real-time measurements.
