## `numastat` collector
```json
"numastat": {}
```
The `numastat` collector reads data from `/sys/devices/system/node/node*/numastat` and outputs a handful **memoryDomain** metrics. See: https://www.kernel.org/doc/html/latest/admin-guide/numastat.html
Metrics:
* `numastats_numa_hit`: A process wanted to allocate memory from this node, and succeeded.
* `numastats_numa_miss`: A process wanted to allocate memory from another node, but ended up with memory from this node.
* `numastats_numa_foreign`: A process wanted to allocate on this node, but ended up with memory from another node.
* `numastats_local_node`: A process ran on this node's CPU, and got memory from this node.
* `numastats_other_node`: A process ran on a different node's CPU, and got memory from this node.
* `numastats_interleave_hit`: Interleaving wanted to allocate from this node and succeeded.
