2.8 Best practices
2.8
1. A Server Configuration Profile (SCP) is better option to configure all the metric reports by including “Custom
Telemetry” option. Once an SCP file is created, the same file can be applied to multiple servers that support
Telemetry feature and Datacenter license.
2. Configure the “report interval” based on the system configuration and number of configured telemetry reports. On
a max config system, a high report interval (2hr) can in-turn result in large telemetry reports since it includes every
relevant device metric. Also, a minimum report interval (10s) can in-turn contribute to processing overheads
based on the number active configured reports.
a. For servers with max configurations (large number of hard drives and or memory cards) it is
recommended to not set the RecurrenceInterval to maximum value.
b. For reports like SystemUsage, PowerMetrics, CPUMemMetrics, ThermalMetrics, and GPUMetrics, it is
recommended to set a minimum RecurrenceInterval of 60s even though the minimum ReportInterval of
10s is allowed.
2.9 Telemetry Error Messages
Telemetry provides error messaging from 2 sources:
• Dell MessageRegistry – prefixed with (IDRAC.)
• Redfish Specification Base MessageRegistry prefixed with (Base.)
o Link to Registry: https://redfish.dmtf.org/registries/Base.1.7.0.json
For ease, iDRAC v4.40.00.00 Telemetry Messages are provided below.
