Managed System PCM Preferences
The managed system PCM preference API is a subset of ManagementConsolePCMpreferences API. This API works on a particular managed system that is connected to HMC and provides APIs enable / disable utilization data collection.
A managed system has the following PCM preferences:
- EnergyMonitoringCapable: This is a read-only attribute and provides information on whether the managed system supports Energy data collection or not. For non-supported managed systems, the value of EnergyMonitoringCapable attribute is false. This attribute is available from HMC 860 SP1 release onwards.
- LongTermMonitorEnabled: Long term monitoring configuration value
- AggregationEnabled: Utilization data aggregation configuration value
- ShortTermMonitorEnabled: Short term monitoring configuration value
- ComputeLTMEnabled: Processor and memory metrics monitoring configuration value
- EnergyMonitorEnabled: Energy monitoring status configuration value
For aggregation of the PCM data, it is essential to have Long Term Monitoring (LTM) enabled. If the user enables only aggregation and does not enable LTM, the application implicitly enables LTM and Energy Monitoring, if the managed system supports Energy monitoring.
The Energy Monitoring flag is available from HMC Version 8 onwards.
