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.

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:

[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.

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.

Examples

Disable swap monitoring.

A basic example that discards swap monitoring

[plugin:macos:sysctl]
  system swap = no
[plugin:macos:mach_smi]
  swap i/o = no

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.
