+## Overview
+
+Information about NUMA (Non-Uniform Memory Access) nodes on the system.
+
+NUMA is a method of configuring a cluster of microprocessor in a multiprocessing system so that they can
+share memory locally, improving performance and the ability of the system to be expanded. 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 |
+
+
+
