NUMA is used in a +symmetric multiprocessing (SMP) system. + +In a NUMA system, processors, memory, and I/O devices are grouped together into cells, also known as nodes. +Each node has its own memory and set of I/O devices, and one or more processors. While a processor can access +memory in any of the nodes, it does so faster when accessing memory within its own node. + +The collector provides statistics on memory allocations for processes running on the NUMA nodes, revealing the +efficiency of memory allocations in multi-node systems. + + + + +This collector is supported on all platforms. + +This collector supports collecting metrics from multiple instances of this integration, including remote instances. + + +### Default Behavior + +#### Auto-Detection + +This integration doesn't support auto-detection. + +#### Limits + +The default configuration for this integration does not impose any limits on data collection. + +#### Performance Impact + +The default configuration for this integration is not expected to impose a significant performance impact on the system. + + +## Metrics + +Metrics grouped by *scope*. + +The scope defines the instance that the metric belongs to.
