Cluster Metrics and Dimensions

Cluster metrics are aggregated by AOM based on host metrics, and do not include the metrics of master nodes.

**Table 1** Cluster metrics
Metric	Description	Value Range	Unit
Total CPU cores (aom_cluster_cpu_limit_core)	Total number of CPU cores that have been applied for a measured object	≥ 1	Cores
Used CPU cores (aom_cluster_cpu_used_core)	Number of CPU cores used by a measured object	≥ 0	Cores
CPU usage (aom_cluster_cpu_usage)	CPU usage of a measured object	0–100	%
Available disk space (aom_cluster_disk_available_capacity_megabytes)	Disk space that has not been used	≥ 0	MB
Total disk space (aom_cluster_disk_capacity_megabytes)	Total disk space	≥ 0	MB
Disk usage (aom_cluster_disk_usage)	Percentage of the used disk space to the total disk space	0–100	%
Available physical memory (aom_cluster_memory_free_megabytes)	Available physical memory of a measured object	≥ 0	MB
Available virtual memory (aom_cluster_virtual_memory_free_megabytes)	Available virtual memory of a measured object	≥ 0	MB
Available GPU memory (aom_cluster_gpu_memory_free_megabytes)	Available GPU memory of a measured object	> 0	MB
GPU memory usage (aom_cluster_gpu_memory_usage)	Percentage of the used GPU memory to the total GPU memory	0–100	%
Used GPU memory (aom_cluster_gpu_memory_used_megabytes)	GPU memory used by a measured object	≥ 0	MB
GPU usage (aom_cluster_gpu_usage)	GPU usage of a measured object	0–100	%
Physical memory usage (aom_cluster_memory_usage)	Percentage of the used physical memory to the total physical memory	0–100	%
Downlink rate (BPS) (aom_cluster_network_receive_bytes)	Inbound traffic rate of a measured object	≥ 0	Byte/s
Uplink rate (BPS) (aom_cluster_network_transmit_bytes)	Outbound traffic rate of a measured object	≥ 0	Byte/s
Total physical memory (aom_cluster_memory_total_megabytes)	Total physical memory that has been applied for a measured object	≥ 0	MB
Total virtual memory (aom_cluster_virtual_memory_total_megabytes)	Total virtual memory that has been applied for a measured object	≥ 0	MB
Virtual memory usage (aom_cluster_virtual_memory_usage)	Percentage of the used virtual memory to the total virtual memory	0–100	%
