## Overview
Collect memory page faults events.
The plugin calls `sysctl` function to collect necessary data
This collector is supported on all platforms.

## 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 vm.stats.vm.v_pgfaults instance
The number of page faults happened on host.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| mem.pgfaults | memory, io_requiring, cow, cow_optimized, in_transit | page faults/s |
