`all-smi` is a command-line utility for monitoring GPU and NPU hardware across multiple systems. It provides a real-time view of accelerator utilization, memory usage, temperature, power consumption, and other metrics. The tool is designed to be a cross-platform alternative to `nvidia-smi`, with support for NVIDIA GPUs, AMD GPUs, NVIDIA Jetson platforms, Apple Silicon GPUs, Intel Gaudi NPUs, Google Cloud TPUs, Tenstorrent NPUs, Rebellions NPUs, and Furiosa NPUs.
The application presents a terminal-based user interface with cluster overview, interactive sorting, and both local and remote monitoring capabilities. It also provides an API mode for Prometheus metrics integration.

See [Building from Source](DEVELOPERS.md#building-from-source) in the developer documentation.
## Usage
### Command Overview
```bash
# Show help
all-smi --help
# Local monitoring (requires sudo on macOS) - default when no command specified
all-smi
sudo all-smi local
# Remote monitoring (requires API endpoints)
all-smi view --hosts http://node1:9090 http://node2:9090
all-smi view --hostfile hosts.csv
# API mode (expose metrics server)
all-smi api --port 9090
```
### Local Mode (Monitor Local Hardware)
The `local` mode monitors your local GPUs/NPUs with a terminal-based interface. This is the default when no command is specified.
```bash
# Monitor local GPUs (requires sudo on macOS)
all-smi # Default to local mode
sudo all-smi local # Explicit local mode
# With custom refresh interval
sudo all-smi local --interval 5
```
### Remote View Mode (Monitor Remote Nodes)
The `view` mode monitors multiple remote systems that are running in API mode. This mode requires specifying remote endpoints.
```bash
# Direct host specification (required)
all-smi view --hosts http://gpu-node1:9090 http://gpu-node2:9090
# Using host file (required)
all-smi view --hostfile hosts.csv --interval 2
```
**Note:** The `view` command requires either `--hosts` or `--hostfile`. For local monitoring, use `all-smi local` instead.
Host file format (CSV):
```
http://gpu-node1:9090
http://gpu-node2:9090
http://gpu-node3:9090
```
## Platform-Specific Requirements
### macOS (Apple Silicon)
- **No sudo required:** Uses native macOS APIs for metrics collection
- Uses IOReport API and Apple SMC directly
- Provides actual temperature readings from SMC sensors
- Run with: `all-smi local`
### Linux with AMD GPUs
- **Sudo Access Required:** AMD GPU monitoring requires `sudo` to access `/dev/dri` devices
- **ROCm Installation:** AMD GPU support requires ROCm drivers and libraries
- **Build Requirements:**
- AMD GPU support is available in **glibc builds only** (`x86_64-unknown-linux-gnu`, `aarch64-unknown-linux-gnu`)
- **Not available in musl builds** (`x86_64-unknown-linux-musl`, `aarch64-unknown-linux-musl`) due to library compatibility
- For static binaries with AMD GPU support, use the glibc builds
- **Permissions:** Add user to `video` and `render` groups as an alternative to sudo:
```bash
sudo usermod -a -G video,render $USER
```
### Linux with NVIDIA GPUs
- **No Sudo Required:** NVIDIA GPU monitoring works without sudo privileges
- **Driver Required:** NVIDIA proprietary drivers must be installed
### Windows
- **No Sudo Required:** GPU and CPU monitoring works without administrator privileges
- **CPU Temperature Limitations:**
- Standard Windows WMI thermal zones (MSAcpi_ThermalZoneTemperature) are not available on all systems
- The application uses a fallback chain to try multiple temperature sources:
1. ACPI Thermal Zones (standard WMI)
2. AMD Ryzen Master SDK (AMD CPUs - requires AMD drivers or Ryzen Master)
3. Intel WMI (Intel CPUs - if chipset drivers support it)
4. LibreHardwareMonitor WMI (any CPU - if [LibreHardwareMonitor](https://github.com/LibreHardwareMonitor/LibreHardwareMonitor) is running)
- If temperature is not available, it will be shown as "N/A" without error messages
- For best temperature monitoring on Windows, install and run LibreHardwareMonitor in the background

### API Mode (Prometheus Metrics)
Expose hardware metrics in Prometheus format for integration with monitoring systems:

all-smi api --port 9090
# Custom update interval (default: 3 seconds)
all-smi api --port 9090 --interval 5
# Include process information
all-smi api --port 9090 --processes
# Unix Domain Socket support (Unix only)
all-smi api --socket # Default path
all-smi api --socket /custom/path.sock # Custom path
all-smi api --port 9090 --socket # TCP + UDS simultaneously
all-smi api --port 0 --socket # UDS only (disable TCP)
# Access via Unix socket
curl --unix-socket /tmp/all-smi.sock http://localhost/metrics
```
**Unix Domain Socket Details:**
- Default paths: `/tmp/all-smi.sock` (macOS), `/var/run/all-smi.sock` or `/tmp/all-smi.sock` (Linux)
- Socket permissions are set to `0600` for security (owner-only access)
- Socket file is automatically cleaned up on shutdown
- Currently Unix-only (Linux, macOS); Windows support pending Rust ecosystem maturity
Metrics are available at `http://localhost:9090/metrics` (TCP) or via Unix socket and include comprehensive hardware monitoring for:
- **GPUs:** Utilization, memory, temperature, power, frequency (NVIDIA, AMD, Apple Silicon, Intel Gaudi, Google TPU, Tenstorrent)
- **CPUs:** Utilization, frequency, temperature, power (with P/E core metrics for Apple Silicon)

For a complete list of all available metrics, see [API.md](API.md).
### Quick Start with Make Commands
For development and testing, you can use the provided Makefile:
```bash
# Run local monitoring
make local
# Run remote view mode with hosts file
make remote
# Start mock server for testing
make mock
# Build release version
make release
# Run tests
make test
```
## Library API
`all-smi` can also be used as a Rust library for building custom monitoring tools or integrating hardware metrics into your applications.
### Add Dependency
Add to your `Cargo.toml`:
```toml
[dependencies]
all-smi = "0.15"
```
### Basic Usage
```rust
use all_smi::{AllSmi, Result};
fn main() -> Result<()> {
// Initialize with auto-detection
let smi = AllSmi::new()?;
// Get all GPU/NPU information
for gpu in smi.get_gpu_info() {
println!("{}: {}% utilization, {:.1}W",
gpu.name, gpu.utilization, gpu.power_consumption);
}
// Get CPU information
for cpu in smi.get_cpu_info() {
println!("{}: {:.1}% utilization", cpu.cpu_model, cpu.utilization);
}
// Get memory information
for mem in smi.get_memory_info() {
println!("Memory: {:.1}% used", mem.utilization);
}
Ok(())
}
```
### Using the Prelude
For convenience, import all common types:
```rust
use all_smi::prelude::*;
fn main() -> Result<()> {
let smi = AllSmi::new()?;
// Types like GpuInfo, CpuInfo, MemoryInfo are available
let gpus: Vec<GpuInfo> = smi.get_gpu_info();
println!("Found {} GPU(s)", gpus.len());
Ok(())
}
```
### Available Methods
| `get_gpu_info()` | `Vec<GpuInfo>` | GPU/NPU metrics (utilization, memory, temp, power) |
| `get_cpu_info()` | `Vec<CpuInfo>` | CPU metrics (utilization, frequency, temp) |
| `get_memory_info()` | `Vec<MemoryInfo>` | System memory metrics |
| `get_process_info()` | `Vec<ProcessInfo>` | GPU process information |
| `get_chassis_info()` | `Option<ChassisInfo>` | Node-level power and thermal info |
### Configuration
```rust
use all_smi::{AllSmi, AllSmiConfig};
let config = AllSmiConfig::new()
.sample_interval(500) // 500ms sample interval
.verbose(true); // Enable verbose warnings
let smi = AllSmi::with_config(config)?;
```
### Thread Safety
`AllSmi` is `Send + Sync` and can be safely shared across threads:
```rust
use std::sync::Arc;
use std::thread;
let smi = Arc::new(AllSmi::new()?);
let smi_clone = smi.clone();
// ...
});
```
