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. An instance is uniquely identified by a set of labels. - - - -### Per numa node - - - -Labels: - -| Label | Description | -|:-----------|:----------------| -| numa_node | TBD | - -Metrics: - -| Metric | Dimensions | Unit | -|:------|:----------|:----| -| mem.numa_nodes | hit, miss, local, foreign, interleave, other | events/s | - - - -## Alerts - -There are no alerts configured by default for this integration. - - -## Setup - -### Prerequisites - -No action required. - -### Configuration - -#### File - -There is no configuration file. -#### Options - - - -There are no configuration options. - -#### Examples -There are no configuration examples. - - |
