## 🇬🇧 English
The **Fleet Control Agent** is a lightweight monitoring script designed for remote nodes (Raspberry Pi / Linux). It collects hardware telemetry and executes commands sent from the Central Dashboard via MQTT.
The **Fleet Control Agent** is a lightweight monitoring and control script designed for remote MMDVM nodes. It acts as the bridge between your radio hardware and the Central Console.
### ✨ Features
* **Real-Time Telemetry:** Monitors CPU usage, RAM, Temperature, and Disk space.
* **Service Management:** Remote Start, Stop, or Restart of system daemons (MMDVMHost, DMRGateway, etc.).
* **Smart Auto-Healing:** Automatically detects crashed services and attempts to revive them.
* **Hardware Reset (GPIO):** Physically reboot the MMDVM radio HAT via GPIO pins directly from the dashboard.
> ️ **Note:** This is the Remote Agent repository, intended to be installed on individual repeater nodes. To manage and monitor all your fleet from a single web dashboard, you must also install the [Fleet Control Console (Server)](https://git.arifvg.it/iv3jdv/fleet-control-server) on your central hub.
### 🚀 Quick Installation
### ✨ Key Features
* **Real-Time Telemetry:** Streams CPU, RAM, Disk usage, and Temperature data via MQTT.
* **Service Management:** Allows remote Start/Stop/Restart of system daemons (MMDVMHost, DMRGateway, etc.).
* **Remote Configuration:** Enables the Central Server to edit `.ini` files remotely.
* **Hardware Reset:** Supports physical MMDVM HAT reset via GPIO pins (requires RPi.GPIO).
* **Auto-Healing:** Automatically detects service failures and attempts to restart them.
1. **Clone the repo:**
### 🤖 Telegram Bot Integration
The agent features built-in support for **Telegram Bot** notifications. This allows system administrators to receive real-time alerts regarding node status, offline services, and critical system events directly on their mobile devices. Notifications are highly manageable: they can be dynamically enabled or muted for each individual node directly from the central NOC Fleet Console, ensuring you only get notified when it matters.
git clone https://git.arifvg.it/iv3jdv/web-control-agent.git web-control
cd web-control
### 🛠️ Core Configuration Files
To enable full functionality, you must configure these three files:
* **`node_config.json`**: The main configuration. Here you set your MQTT broker, your unique `client_id` (e.g., `IR3XXX`), and the paths for the lists below.
* **`process_list.txt`**: List the names of the system services you want to monitor (e.g., `mmdvmhost`, `dmrgateway`). The agent will check their status and attempt to restart them if they crash (Auto-healing).
* **`file_list.txt`**: List the full absolute paths of the configuration files (e.g., `/etc/MMDVMHost.ini`) that you want to edit remotely from the Dashboard.
2. **Install dependencies:**
### 🚀 Installation Guide
pip install -r requirements.txt
#### 0. Root Privileges
All installation steps must be executed as the `root` user. Before starting, elevate your privileges by running:
```bash
sudo su
```
3. **Configure:** Edit `node_config.json` with your MQTT credentials and a unique `client_id`.
4. **Run:** `python3 system_monitor.py`
#### 1. Clone the Repository
Clone the agent into `/opt` to ensure path consistency:
```bash
sudo git clone https://git.arifvg.it/iv3jdv/fleet-node-agent.git /opt/fleet-node-agent
cd /opt/fleet-node-agent
```
#### 2. Virtual Environment Setup
```bash
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```
#### 3. Configuration
1. **Main Config**: `cp node_config.json.example node_config.json` and edit it with your MQTT credentials.
2. **Processes**: `cp process_list.txt.example process_list.txt` and add your service names (one per line).
3. **Files**: `cp file_list.txt.example file_list.txt` and add the absolute paths to your `.ini` files.
**Note:** To enable Telegram notifications, ensure you have configured your `TELEGRAM_TOKEN` and `CHAT_ID` in the agent's configuration file.
#### 4. Systemd Service (Auto-start)
```bash
cp fleet-agent.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable fleet-agent
systemctl start fleet-agent
```

## 🇮🇹 Italiano
Il **Fleet Control Agent** è uno script di monitoraggio leggero progettato per i nodi remoti (Raspberry Pi / Linux). Raccoglie la telemetria hardware ed esegue i comandi inviati dalla Dashboard Centrale tramite protocollo MQTT.
Il **Fleet Control Agent** è lo script di monitoraggio e controllo per i nodi remoti MMDVM. Funge da ponte tra l'hardware radio e la Console Centrale.
### ✨ Funzionalità
* **Telemetria in Tempo Reale:** Monitoraggio di utilizzo CPU, RAM, Temperatura e spazio su Disco.
* **Gestione Servizi:** Avvio, arresto o riavvio remoto dei demoni di sistema (MMDVMHost, DMRGateway, ecc.).
* **Auto-Healing Intelligente:** Rileva automaticamente i servizi andati in blocco e tenta di riavviarli autonomamente.
* **Reset Hardware (GPIO):** Invia un impulso di reset fisico alla scheda radio MMDVM tramite i pin GPIO direttamente dalla dashboard.
> ️ **Nota:** Questo è il repository dell'Agent Remoto, da installare sui singoli nodi ripetitore. Per gestire e monitorare tutta la flotta da un'unica dashboard web, devi installare anche la [Fleet Control Console (Server)](https://git.arifvg.it/iv3jdv/fleet-control-server) sul tuo hub centrale.
### 🚀 Installazione Rapida
1. **Clona il repository:**
### ✨ Funzionalità Principali
* **Telemetria Real-Time:** Invia dati su CPU, RAM, Disco e Temperatura via MQTT.
* **Gestione Servizi:** Permette l'avvio, l'arresto o il riavvio remoto dei demoni di sistema (MMDVMHost, DMRGateway, ecc.).
* **Configurazione Remota:** Consente al Server Centrale di modificare i file `.ini` a distanza.
* **Reset Hardware:** Supporta il reset fisico della scheda MMDVM HAT tramite pin GPIO (richiede RPi.GPIO).
* **Auto-Healing:** Rileva automaticamente i crash dei servizi e tenta di riavviarli.
git clone https://git.arifvg.it/iv3jdv/web-control-agent.git web-control
cd web-control
### 🤖 Telegram Bot Integration
L'agent dispone del supporto nativo per le notifiche tramite **Bot Telegram**. Questo permette agli amministratori di sistema di ricevere alert in tempo reale sullo stato dei nodi, sui servizi offline e sugli eventi critici direttamente sul proprio smartphone. La gestione degli avvisi è centralizzata: le notifiche possono essere attivate o silenziate dinamicamente per ogni singolo nodo direttamente dalla Fleet Console centrale, evitando spam inutile.
2. **Installa le dipendenze:**
### 🛠️ File di Configurazione Chiave
Per il corretto funzionamento, è necessario definire i parametri in questi tre file:
* **`node_config.json`**: La configurazione principale. Qui imposti il broker MQTT, il tuo `client_id` univoco (es. `IR3XXX`) e i percorsi per le liste sottostanti.
* **`process_list.txt`**: Elenca i nomi dei servizi di sistema da monitorare (es. `mmdvmhost`, `dmrgateway`). L'agente ne controllerà lo stato e proverà a riavviarli in caso di crash (Auto-healing).
* **`file_list.txt`**: Elenca i percorsi completi dei file di configurazione (es. `/etc/MMDVMHost.ini`) che desideri poter modificare remotamente dalla Dashboard.
pip install -r requirements.txt
### 🚀 Guida all'Installazione
3. **Configurazione:** Modifica il file `node_config.json` inserendo le tue credenziali MQTT e un `client_id` univoco.
4. **Avvio:** `python3 system_monitor.py`
#### 0. Privilegi di Root
Tutti i passaggi di installazione devono essere eseguiti come utente `root`. Prima di iniziare, eleva i tuoi privilegi eseguendo:
```bash
sudo su
```
#### 1. Clonazione del Repository
Clona l'agente nella cartella `/opt` per garantire la coerenza con i servizi systemd:
```bash
sudo git clone https://git.arifvg.it/iv3jdv/fleet-node-agent.git /opt/fleet-node-agent
cd /opt/fleet-node-agent
```
#### 2. Setup Ambiente Virtuale (venv)
```bash
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```
#### 3. Personalizzazione
1. **Config Principale**: `cp node_config.json.example node_config.json` e inserisci i dati MQTT.
2. **Processi**: `cp process_list.txt.example process_list.txt` e aggiungi i nomi dei tuoi servizi (uno per riga).
3. **File**: `cp file_list.txt.example file_list.txt` e inserisci i percorsi assoluti dei tuoi file `.ini`.
**Nota:** Per abilitare le notifiche Telegram, assicurati di aver configurato il tuo `TELEGRAM_TOKEN` e il `CHAT_ID` nel file di configurazione dell'agent.
#### 4. Esecuzione come Servizio (systemd)
```bash
cp fleet-agent.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable fleet-agent
systemctl start fleet-agent
```
