Node metrics

Table 5. Node metrics
Metric name	Description
CPU Usage	CPU usage on all cores in millicores
CPU Usage Rate	CPU usage rate on all cores in millicores/second
CPU Request	CPU request (the guaranteed amount of resources) in millicores
CPU Limit	CPU hard limit in millicores
CPU Utilization	CPU utilization as a share of node allocatable
Memory Usage	Total memory usage in bytes
Memory Working Set	Total working set usage. Working set is the memory being used and not easily dropped by the kernel.
Memory Rss	RSS memory usage
Memory Request	Memory request (the guaranteed amount of resources) in bytes
Memory Limit	Memory hard limit in bytes
Memory Page Faults	Number of page faults
Memory Major Page Faults	Number of major page faults
Memory Page Faults Rate	Number of page faults per second
Memory Major Page Faults Rate	Number of major page faults per second
Memory Utilization	Memory utilization as a share of memory allocatable
