| NUM_CPUS |
Number of CPUs or processors available |
| IDLE_TIME |
Number of hundredths of a second that a processor has been idle, totalled over all processors |

| IOWAIT_TIME |
Number of hundredths of a second that a processor has been waiting for I/O to complete, totalled over all processors |
| NICE_TIME |
Number of hundredths of a second that a processor has been busy executing low-priority user code, totalled over all processors |
| AVG_IDLE_TIME |
Number of hundredths of a second that a processor has been idle, averaged over all processors |
| AVG_BUSY_TIME |

| OS_CPU_WAIT_TIME |
Total number of hundredths of a second that processes have been in a ready state, waiting to be selected by the operating system scheduler to run |
| RSRC_MGR_CPU_WAIT_TIME |
Total number of hundredths of a second that Oracle processes have been in a ready state, waiting for CPU to be available for their consumer group in the currently active resource plan |
| VM_PAGE_IN_BYTES |
Total number of bytes of data that have been paged in due to virtual memory paging |
| VM_PAGE_OUT_BYTES |
Total number of bytes of data that have been paged out due to virtual memory paging |
| PHYSICAL_MEMORY_BYTES |
Total number of bytes of physical memory |
| LOAD |
Current number of processes that are either running or in the ready state, waiting to be selected by the operating-system scheduler to run. On many platforms, this statistic reflects the average load over the past minute. |
| NUM_CPU_CORES |
Number of CPU cores available (includes subcores of multicore CPUs as well as single-core CPUs) |
| NUM_CPU_SOCKETS |
Number of CPU sockets available (represents an absolute count of CPU chips on the system, regardless of multithreading or multi-core architectures) |
