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.
Introduction 1 Introduction This white paper introduces iDRAC9 telemetry performance reports, and respective metrics in those reports. The iDRAC9 telemetry reports can be pulled on demand through Redfish APIs. Or the reports can be configured to be streamed through HTTP subscription, remote syslog, or Server-Sent Events (SSE) based methods. For best practices, troubleshooting tips and details on setting up the telemetry report streams, see the Telemetry Streaming “Getting Started” white paper. 1.
Server Performance metrics and workflows 2 Server Performance metrics and workflows This section describes the telemetry performance reports, metrics, and workflows to derive useful insights. 2.1 System Usage report metrics The Compute Usage Per Second (CUPS) report is available on Intel-based server platforms. CUPS report enables real-time performance monitoring data for CPU, memory, I/O, and system utilization.
Server Performance metrics and workflows In the example, the output compares the telemetry report queried from an Intel-based Dell EMC PowerEdge server before and after the naming schema modification has been implemented. AMD-based Dell EMC PowerEdge servers will differ when compared with Intel-based servers.
Server Performance metrics and workflows 2.5 Workflows and Examples iDRAC9 telemetry feature for downstream analytics and visualization by plotting streamed metric values for gaining useful insights. The image below shows a plot of System Usage metric values.
