sysgraph 0.0.14

Visualizer for processes and their interconnections

sysgraph

Real-time process-graph visualizer that discovers running OS processes, their inter-process communication channels (pipes, Unix domain sockets, TCP/UDP network connections), and renders them as an interactive force-directed graph in the browser.

Features

• Process discovery — enumerates all running OS processes and their parent-child relationships
• IPC visualization — discovers pipes, Unix domain sockets, and TCP/UDP connections between processes
• Interactive graph — force-directed graph rendered in the browser with zoom, pan, drag, and search
• Real-time — fetch the latest process graph on demand via the web UI
• Fuzzy search — find processes by name, PID, command line, or any property
• Adjacency filtering — right-click a node to show only its neighbors
• Configurable — tune d3 force parameters, colors, and filters via the settings panel
• Export/Import — save and load graph snapshots as JSON

Requirements

• Linux (relies on /proc filesystem and the ss command)
• Python ≥ 3.12
• Root/sudo recommended for full visibility into all processes

Installation

pip install sysgraph

Usage

# Start the web server (default: http://localhost:8000)
sysgraph

# Specify a custom port
sysgraph --port 9000

# Or run as a module
python -m sysgraph

Open your browser to the displayed URL to see the interactive process graph.

For full visibility into all processes and their connections, run with elevated privileges:

sudo sysgraph

Docker

docker run --rm -it --pid=host --net=host gubenkoved/sysgraph

The --pid=host and --net=host flags allow the container to see host processes and network connections.

How It Works

1. The FastAPI backend uses psutil and Linux-specific APIs (/proc, ss) to discover processes, pipes, Unix domain sockets, and network connections.
2. It builds a graph of processes (nodes) and their IPC channels (edges).
3. The browser frontend fetches the graph via GET /api/graph and renders it using force-graph with d3 physics simulation.
