Metric Injection (Host OS Telemetry)

The Metric Injection (Host OS Telemetry) feature in iDRAC Service Module (iSM) collects metrics from the operating system and injects the metrics data into the iDRAC telemetry interface. The metric injection to the iDRAC telemetry is performed over HTTPS requests following the Redfish standards. iSM supports the Metric Injection (Host OS Telemetry) feature on Microsoft Windows, Linux, and VMware ESXi 8.0 U2 operating systems, with iDRAC firmware 6.10.00.00 and later versions.

Following are the prerequisites for the Metric Injection (Host OS Telemetry) feature:

  • iDRAC Datacenter license
  • iDRAC and host operating system time must be synchronized
  • The Metric Injection (Host OS Telemetry) feature must be installed on iSM
  • Enable the iDRAC web server in the iDRAC UI or RACADM CLI by running the following command: 
    racadm set idrac.webserver.enable 1
  • Enable Redfish service in the iDRAC UI or RACADM CLI by running the following command: 
    racadm set iDRAC.Redfish.Enable 1
  • Enable the telemetry feature in RACADM CLI by running the following commands: 
    racadm set iDRAC.Telemetry.EnableTelemetry 1
    racadm set idrac.Telemetry.EnableMetricInjection 1
NOTE:
  • The Metric Injection (Host OS Telemetry) feature of iSM does not create metric reports on iDRAC. To view the metric values that are injected by iSM to the iDRAC telemetry, you must create the metric report for the required metrics.
  • The Metric Injection (Host OS Telemetry) feature is not supported when iSM is running in Limited Functionality mode.
  • During iDRAC factory reset, the metric information is deleted from the iDRAC.
  • The Metric Injection (Host OS Telemetry) feature supports a maximum of 48 metric values on iDRAC firmware 7.00.60.00 and earlier versions.

The Metric Injection (Host OS Telemetry) feature collects static and dynamic metrics from the host operating system. The static metrics are injected only when the iSM service starts or restarts, and the dynamic metrics have a default update interval of three minutes. The following table lists the static and dynamic metrics that are injected to the iDRAC telemetry:
