This plugin has the ability to gather LLC Occupancy, Memory Bandwidth Occupancy and list RDT capabilities of platform.
- LLC Occupancy metric is available from Haswell (Xeon v3) platform.
- Memory Bandwidth metric is available from Broadwell (Xeon v4) platform.
- Capabilities are always returned with metrics.
