Users Guide

● StorageSensor data is reported only for the drives in Ready / Online / Non-RAID mode and not behind the BOSS
controller.
● NVMeSMARTData is only supported for SSD (PCIeSSD / NVMe Express) drives with PCIe bus protocol (not behind
SWRAID).
● GPGPUStatistics data is only available in specific GPGPU models that support ECC memory capability.
● PSUMetrics is not available on modular platforms.
● Fan Power and PCIe Power Metrics may be displayed as 0 for some platforms.
● CUPS report has been renamed to SystemUsage in 4.40.00.00 release and it's supported on both INTEL and AMD
platforms.
Telemetry Workflow:
1. Install Datacenter license, if not installed already.
2. Configure global Telemetry settings including Enabling the telemetry and Rsyslog server network address and port using
RACADM, Redfish, SCP, or iDRAC GUI.
3. Configure the following Telemetry report streaming parameters on the required device report or log using either RACADM or
Redfish interface:
● EnableTelemetry
● ReportInterval
● ReportTriggers
NOTE: Enable iDRAC Alerts and Redfish events for the specific hardware for which you need telemetry reports.
4. Redfish client makes subscription request to the Redfish EventService on iDRAC.
5. iDRAC generates and pushes the metric report or log/event data to the subscribed client when the predefined trigger
conditions are met.
Feature Constraints:
1. For security reasons, iDRAC supports only HTTPS-based communication to the client.
2. For stability reasons, iDRAC supports up to eight subscriptions.
3. Deletion of subscriptions is supported through Redfish interface only, even for the manual deletion by the Admin.
Behavior of Telemetry feature:
● iDRAC generates and pushes (HTTP POST) the Metric Report or log/event data to all the subscribed clients to the
destination specified in the subscription when the predefined trigger conditions are met. The clients receive new data only
upon successful subscription creation.
● The metric data includes the timestamp in ISO format, UTC time (ends in 'Z'), at the time of data collection from source.
● Clients can terminate a subscription by sending an HTTP DELETE message to the URI of the subscription resource through
the Redfish interface.
● If the subscription is deleted either by iDRAC or the client, then iDRAC does not send (HTTP POST) reports. If the number
of delivery errors exceeds predefined thresholds, then iDRAC may delete a subscription.
● If a user has Admin privilege, they can delete the subscriptions but only through Redfish interface.
● Client is notified about the termination of a subscription by iDRAC by sending 'Subscription terminated' event as the last
message.
● Subscriptions are persistent and can remain even after iDRAC restarts. But, they can be deleted either by performing
racresetcfg or LCwipe operations.
● User interfaces like RACADM, Redfish, SCP, and iDRAC display the current status of the client subscriptions.
Serial Data Capture
iDRAC allows you to capture console redirection serial for later retrieval with the use of Serial Data Capture feature. This feature
requires iDRAC Datacenter license.
The purpose of Serial Data Capture feature is to capture the system serial data and store it so that the customer can later
retrieve it for debugging purpose.
You can enable or disable a serial data capture using RACADM, Redfish, iDRAC interfaces. When this attribute is enabled, iDRAC
will capture serial traffic received on Host Serial Device2 irrespective of serial Mux mode settings.
To enable / disable Serial Data Capture using iDRAC GUI, go to Maintainance > Diagnostics > Serial Data Logs page, and
check the box to enable or disable.
