White Paper Telemetry Streaming with iDRAC9 - Power and Thermal Metrics Abstract Dell EMC PowerEdge Servers with iDRAC9 4.x Datacenter streams data to help IT administrators better understand the inner workings of their server environment. This white paper explains how to use the Telemetry Power and Thermal reports for monitoring and creating graphs for PowerEdge server power and thermal subsystems.

Executive summary Executive summary Beginning with iDRAC9 v4.00.00.00 firmware and a Datacenter license, IT managers can integrate advanced server hardware operation telemetry into their existing analytics solutions. Telemetry is provided as granular, timeseries data that is streamed, or pushed, compared to inefficient, legacy polling, or pulled, methods. The advanced agent-free architecture in iDRAC9 provides over 180 data metrics that are related to server and peripherals operations.
Telemetry Overview 1 Telemetry Overview 1.1 Terms and Definitions Telemetry: Telemetry is an automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. Telemetry Report: Telemetry (Metric) Report is a DMTF Telemetry specification-compliant JSON document that consists of Metric names, Metric values, and Timestamps.
