In AOM, VMs refer to processes, and VM metrics refer to process metrics.

**Table 1** Process metrics
Metric	Description	Value Range	Unit
Total CPU cores (aom_process_cpu_limit_core)	Total number of CPU cores that have been applied for a measured object	≥ 1	Cores
Used CPU cores (aom_process_cpu_used_core)	Number of CPU cores used by a measured object	≥ 0	Cores
CPU usage (aom_process_cpu_usage)	CPU usage of a measured object. That is, the percentage of the used CPU cores to the total CPU cores.	0–100	%
Handles (aom_process_handle_count)	Number of handles used by a measured object	≥ 0	N/A
Max. handles (aom_process_max_handle_count)	Maximum number of handles used by a measured object	≥ 0	N/A
Total physical memory (aom_process_memory_request_megabytes)	Total physical memory that has been applied for a measured object	≥ 0	MB
Physical memory usage (aom_process_memory_usage)	Percentage of the used physical memory to the total physical memory	0–100	%
Used physical memory (aom_process_memory_used_megabytes)	Used physical memory of a measured object	≥ 0	MB
Status (aom_process_status)	Process status	0 or 1 0: Normal 1: Abnormal	N/A
Threads (aom_process_thread_count)	Number of threads used by a measured object	≥ 0	N/A
Total virtual memory (aom_process_virtual_memory_total_megabytes)	Total virtual memory that has been applied for a measured object	≥ 0	MB
