Hardware Info

The Hardware Info page gives you a comprehensive, read-only inventory of your system’s components. Unlike the Dashboard (which focuses on live utilization), this page shows static specifications — model names, capacities, core counts, and health ratings that do not change from second to second.

All data is collected once when you first visit the page, so there is no ongoing performance cost.

Hardware Info page

Sections

The page is divided into eight collapsible sections. Each one is a table of key-value pairs relevant to that hardware category.

System

General information about your machine and operating system.

Field	Description
Hostname	Your computer’s network name
Operating System	Distribution or macOS version
Kernel	Linux kernel version or Darwin/XNU version
Architecture	CPU architecture (x86_64, arm64, etc.)
Desktop Environment	GNOME, KDE, Aqua, etc.

Processor

Details about your CPU.

Field	Description
Model Name	Full marketing name of the processor
Physical Cores	Number of physical CPU cores
Logical Cores	Number of threads (includes hyper-threading)
Base Clock	Default clock speed
L1 / L2 / L3 Cache	Size of each cache level

Graphics

Your GPU(s) and their vendors.

Field	Description
GPU Name	Model name of each graphics processor
Vendor	Manufacturer (NVIDIA, AMD, Intel, Apple)

Linux: Detected via sysfs for AMD and Intel, nvidia-smi for NVIDIA cards.

macOS: Detected via IOKit and Metal APIs.

A Copy GPU Diagnostics button at the bottom of the Graphics section copies a detailed diagnostic snapshot to your clipboard — GPU names, vendors, and detection method. This is useful when filing a bug report or asking for help with GPU-related issues.

Memory

System memory totals.

Field	Description
Total RAM	Installed physical memory
Total Swap	Configured swap space

Battery

Shown only on devices with a battery.

Field	Description
Design Capacity	Original factory capacity
Current Max Capacity	Maximum charge the battery can currently hold
Cycle Count	Number of full charge-discharge cycles
Health	Percentage of original capacity remaining

Storage

One row per detected drive, with SMART health data.

Field	Description
Name	Drive identifier or mount point
Size	Total capacity
Model	Drive model string
Health	SMART health verdict with color coding

Health Color Coding

The health verdict uses a simple traffic-light system:

Good (green) — The drive is healthy. No action needed.
Caution (yellow) — Some SMART attributes are degrading. Consider backing up and monitoring closely.
Critical (red) — The drive is reporting failures. Back up your data immediately and plan a replacement.

Tip: Storage health is determined by reading SMART attributes via smartctl. On macOS, Nexis also uses diskutil for additional metadata. If smartctl is not installed, health data may be unavailable.

Linux — limited permissions: If Nexis is running as a normal user and smartctl requires root access to query a drive, that drive will show “Limited data” and an Unlock button inline. If more than one drive needs elevation, an Unlock All Drives button appears at the top of the Storage section.

Clicking either button opens a single authentication dialog (polkit / pkexec). The dialog includes a Make Permanent checkbox — when checked, Nexis runs setcap cap_sys_rawio+ep on the smartctl binary in the same elevated session, so future launches no longer require a password prompt. Once you approve, all locked drives are re-read in a single operation.

For more detail, see the Troubleshooting page.

Network

One row per network interface.

Field	Description
Interface	Name of the network adapter (e.g., eth0, en0, wlan0)
MAC Address	Hardware address
IP Addresses	IPv4 and/or IPv6 addresses assigned to the interface

Thermal

Sensor readings from available temperature probes.

Field	Description
Sensor	Name or label of the thermal sensor
Temperature	Current reading

Linux: Reads from /sys/class/hwmon/ entries.

macOS: Reads from the System Management Controller (SMC).

Export System Report

Click the Export button at the top of the page to save a complete text summary of all hardware information to a file. A save dialog appears with a default filename of nexis-report-YYYY-MM-DD.txt.

The report includes every section visible on the page — System, Processor, Graphics, Memory, Battery, Fans, and Storage — formatted as labeled key-value pairs. The report also contains the Nexis version number and a timestamp. This is useful for:

Sharing specs when asking for technical support or posting to forums.
Archiving your hardware configuration before and after upgrades.
Comparing multiple machines side by side.
