To know about the field descriptions of Telemetry section, see iDRAC Online Help.
NOTE:
● StorageDiskSMARTDATA is only supported on SSD drives with SAS/SATA bus protocol and behind the BOSS controller.
● 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.

串行数据捕获
iDRAC 允许使用串行数据捕获功能捕获控制台重定向串行，以便稍后检索。此功能需要 iDRAC Datacenter 许可证。
串行数据捕获功能的目的是捕获系统序列数据并将其存储起来，以便客户稍后出于调试目的检索。
