# macOS
Plugin: macos.plugin
Module: mach_smi
## Overview
Monitor macOS metrics for efficient operating system performance.
The plugin uses three different methods to collect data:
- The function `sysctlbyname` is called to collect network, swap, loadavg, and boot time.
- The functtion `host_statistic` is called to collect CPU and Virtual memory data;
- The function `IOServiceGetMatchingServices` to collect storage information.
This collector is only supported on the following platforms:
- macOS
This collector only supports collecting metrics from a single instance of this integration.
### 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 macOS instance
These metrics refer to hardware and network monitoring.
This scope has no labels.

## Setup
### Prerequisites
No action required.
### Configuration
#### File
The configuration file name for this integration is `netdata.conf`.
The file format is a modified INI syntax. The general structure is:
```ini
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
```
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf
```
#### Options
There are three sections in the file which you can configure:
- `[plugin:macos:sysctl]` - Enable or disable monitoring for network, swap, loadavg, and boot time.
- `[plugin:macos:mach_smi]` - Enable or disable monitoring for CPU and Virtual memory.
- `[plugin:macos:iokit]` - Enable or disable monitoring for storage device.
