Supported metrics
PowerVC stores metrics based on aggregation. For 15 minutes of aggregation, metrics are stored for a period of 10 days. For 1 hour and 6 hours of aggregation, metrics are stored for a period of 30 days.
| Resource type | Metric | Description |
|---|---|---|
| nova_compute(1) | compute.node.cpu.percent |
CPU utilization of the host. |
compute.node.memory.percent |
Memory utilization of the host. | |
| instance(2) | cpu_util |
CPU utilization of the virtual machine. |
mem_util(3) |
Memory utilization of the virtual machine. For the known problems and solutions for memory utilization of the virtual machine, see Memory utilization of a virtual machine shows full utilization when RMC is inactive. | |
| instance_network_interface | network.incoming.bytes |
The count of the bytes received by the client Network Adapter. |
network.outgoing.bytes |
The count of the bytes sent by the client Network Adapter. | |
| instance_disk | disk.device.read.bytes |
The number of bytes read from the storage adapter. |
disk.device.write.bytes |
The number of bytes written to the storage adapter. | |
disk.vfc.aggregated.read.bytes |
The cumulative number of bytes read from the storage adapter across all virtual Fibre Channel (VFC) interfaces. | |
disk.vfc.aggregated.write.bytes |
The cumulative number of bytes written to the storage adapter across all virtual Fibre Channel (VFC) interfaces. | |
|
cloud_aggregated_metrics |
total_vcpu |

total_memory |
The amount of memory being used by virtual machines. | |
total_volumes |
The amount of storage being used by volumes. | |
