Network Statistics Collector

A high-performance network statistics collector for router servers, built using eBPF and gRPC.

Features

• Real-time IPv4 and IPv6 connection statistics collection
• Kernel-level tracking using eBPF
• Efficient gRPC communication with TLS support
• JSON configuration file support
• Hot-reloadable configuration
• Comprehensive connection tracking
• Memory-efficient implementation
• Systemd service integration

Requirements

• Linux kernel 5.8 or newer (for eBPF features)
• CMake 3.10 or newer
• GCC or Clang
• libbpf
• OpenSSL
• gRPC
• Protocol Buffers
• JSON-C

Building

1. Clone the repository:

git clone https://github.com/yourusername/network-stats-collector.git
cd network-stats-collector

2. Run the build script:

chmod +x build.sh
./build.sh

Configuration

The collector is configured using a JSON file. A sample configuration is provided in config.json.

Configuration Options

• push_interval_ms: Interval between data pushes (milliseconds)
• log_level: Logging level (DEBUG, INFO, WARN, ERROR)
• log_file: Path to log file
• endpoints: Array of gRPC endpoints to push data to
• use_tls: Enable/disable TLS
• ca_cert: Path to CA certificate
• client_cert: Path to client certificate
• client_key: Path to client private key
• batch_size: Maximum number of connections to batch before pushing
• max_connections: Maximum number of connections to track

Usage

1. Install the service:

sudo systemctl enable collector

2. Start the service:

sudo systemctl start collector

3. Check the status:

sudo systemctl status collector

4. View logs:

sudo journalctl -u collector -f

Security

• The collector uses mutual TLS authentication
• Runs with minimal privileges
• Secure communication channels
• Memory-safe implementation

Performance

The collector is optimized for performance:

• Uses eBPF for kernel-level tracking
• Implements zero-copy techniques
• Uses batched processing
• Minimizes memory allocations
• Uses lock-free data structures
