1 Telemetry overview
Telemetry streaming is an automated communications process by which measurements and other data are
collected at remote or inaccessible points. With iDRAC9 4.0 Datacenter, it is possible to stream a wide variety
of metric reports from one or more PowerEdge servers to an ingress collector such as Splunk or ELK Stack.
These and other tools can then perform remote server monitoring and analysis.
The following diagram shows the basic elements used for Telemetry Streaming Analytics
This paper will focus on the items under iDRAC control, as shown below.
