CLI-Based Distributed DAQ Simulator (ZeroMQ + tmux)

This is a command-line DAQ-style simulation system built with C++ and ZeroMQ, designed for real-time control and visualization using tmux. It mimics a particle physics detector pipeline, featuring:

• 🛰️ Multiple Detectors generating random events
• ⚙️ A Broker that load-balances data
• 🧠 Multiple Workers processing the data
• 📥 A Collector tallying total hits
• 📡 A Monitor Bus relaying system logs
• 🧾 A Monitor CLI dashboard
• 🕹️ A CCM (Command & Control Module) to gracefully shut everything down

🧱 Architecture

        +-----------+          +---------+         +-----------+
        | Detectors | PUSH --> | Broker  | PUSH -->|  Workers  |
        +-----------+          +---------+         +-----------+
                                   |                    |
                              Control via              PUSH
                              zmq::proxy()              |
                                   v                 +--------+
                               +--------+ <-------- | Collector |
                               |  CCM   |           +--------+
                               | PUB --> all        (tallies PARTICLEs)

Log Flow:

All components PUSH logs to monitor_bus (PULL → PUB), which are displayed in a monitor (SUB) pane in tmux.

🖥️ Live View

Launches into a live tmux session with all components in a tiled layout.
Use the top-left CCM pane to type shutdown and gracefully exit all components.

🚀 Quickstart (Fedora)

1. Install dependencies

sudo dnf install -y gcc-c++ cmake make tmux zeromq zeromq-devel

2. Clone and run

git clone <this repo>
cd ZeroMQ-C-plus-plus-DAQ
chmod +x run_all_tmux.sh
./run_all_tmux.sh

The script will:

• Build all components
• Start a tmux grid view
• Stream logs
• Wait for you to type shutdown

📦 Components

Component	Description
ccm	Command interface (sends shutdown)
broker	Load balances data between detector/worker
collector	Tallies up processed hits
detector	Sends random PARTICLE / MISS events
worker	Processes and forwards only PARTICLEs
monitor_bus	Relays logs to monitor
monitor	Displays logs in a clean CLI view

---

🧹 Cleanup

tmux kill-session -t daq_grid
