Telemetry is standard that allows one-to-many solution for collecting and streaming the live system data from one or more PowerEdge servers (iDRAC) to a centralized Remote Server Monitoring, Analysis, and Alerting service. Telemetry enables you to collect metric and data logs from various devices on PowerEdge server and stream that data to the subscribed external client or server application. Using telemetry, it is possible to set types of reports and the frequency of reports that needs to be generated. To take advantage of this feature, ensure that you have the Datacenter license installed in iDRAC and Telemetry along with Reports is enabled in iDRAC. For more information about Telemetry Streaming, see the iDRAC User's Guide.

The Telemetry model has Telemetry Service with four subordinate collection resources:

• Metric Definitions - these contain the definition of metric properties (characteristics, metadata).
• Metric Report Definitions - contains definition of metric reports that will be generated on request.
• Metric Reports - this contains metric definitions that creates a metric report.
• Triggers - these contain threshold triggers and actions that apply to a metric property.

Telemetry reports can be accessed through the following channels:

1. Pull or perform GET on MetricReport.
2. Server-Sent Events
