• Telemetry Report: A Telemetry report is a DMTF Redfish Telemetry Specification compliant JSON document. It describes time-series data consisting of metric names, metric values, and timestamps.
• Metric Report Definition (MRD): Metric Report Definitions (MRD) is a DMTF-compliant JSON document that describes how a Telemetry Report should be generated and what content it should include. The report output is controlled by the MRD, which contains a list of Metric IDs to include, along with overall configuration details about the report's behavior.
• Metric Definition (MD): Metric Definition (MD) is a DMTF-compliant JSON document that describes the attributes of a metric, such as its ID, description, datatype , units, sensing interval, and more.
• Trigger: Trigger is a DMTF compliant JSON document defining a set of conditions and associated Metric Reports that should be generated and streamed. The conditions can include a system event or a user-defined condition, such as a metric value crossing a threshold limit or equal to a discrete value.
• SSE: Server-Sent Events(SSE) allows a client to open a web service connection to iDRAC, enabling telemetry data to be continuously pushed to the client as needed.
• SupportAssist Collection: Dell SupportAssist Collection is a feature that gathers system diagnostics, hardware logs, and configuration data from Dell PowerEdge servers. It helps with proactive troubleshooting, issue detection, and streamlined support case creation.
• iSM (Integrated Service Module) is a set of tools for monitoring server health, performance, and configurations. It collects metrics, manages firmware, and integrates with SupportAssist for proactive issue resolution.
