# macOS


<img src="https://netdata.cloud/img/macos.svg" width="150"/>


Plugin: macos.plugin
Module: mach_smi

<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />

## 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.
