JSON specification for Energy Monitoring Processed and Aggregated Metrics

All the parameters for the Processed and Aggregated metrics are same except that the Processed metrics provides only Average metrics, and it does not provide minimum and maximum records. The PCM Processed or Aggregated metrics URI for Energy Monitoring provides the following power consumption and thermal data when the AggregationEnabled parameter is enabled for a managed system.

Table 1. Description of metric parameters
Metric name	Description
Version	Version of JSON format for Energy Monitoring.
metricType	Type of the sample. The values are Processed or Aggregated.
frequency	The collection cycle in seconds.
startTimeStamp	Start Timestamp of the samples collected
endTimeStamp	End Timestamp of the samples collected
uuid	UUID of the Managed System
name	name of the Managed System
mtms	Machine Type, Model, and Serial number of the Managed System
metricArrayOrder	AVG, MIN, and MAX. For Processed metrics, the value is AVG
utilSamples: Containing sample of Processed or Aggregated Energy Monitoring metrics.
sampleType	Type of the sample. The value is ManagedSystem
energyUtil	Contains the Energy & Power related data
powerUtil	Power consumption data
powerReading	Power consumed by the system for the specific interval, in watt
thermalUtil	Data related to heat generated by the managed system
inletTemperatures	Generated heat data for the Inlet
cpuTemperatures	Generated heat data for the CPUs
baseboardTemperatures	Generated heat data for the Baseboards
entityId	The ID of the entity. The value can be Inlet, CPU, or Baseboard.
