# Trippy：新一代 TUI 路由追踪工具（Rust 编写，比 MTR 更现代）
# 安装（Debian/Ubuntu）
wget https://github.com/fujiapple852/trippy/releases/latest/download/trippy-x86_64-unknown-linux-gnu.tar.gz
tar xzf trippy-x86_64-unknown-linux-gnu.tar.gz
mv trip /usr/local/bin/

# 运行（交互式 TUI，实时更新，支持 ICMP/UDP/TCP 多协议）
trip 8.8.8.8

# 报告模式（类似 mtr -r）
trip --report-cycles 10 8.8.8.8

# Bandwhich：按进程/连接实时显示带宽占用（Rust 编写）
# 安装
wget https://github.com/imsnif/bandwhich/releases/latest/download/bandwhich-x86_64-unknown-linux-gnu.tar.gz
tar xzf bandwhich-*.tar.gz && mv bandwhich /usr/local/bin/

# 运行（需要 root 权限，实时显示哪个进程/IP 在消耗带宽）
sudo bandwhich

# nethogs：同类工具，更轻量，apt 直接安装
apt install nethogs -y && nethogs

# 文件路径：/opt/smokeping/docker-compose.yml
# Smokeping：长期监控延迟波动，生成历史图表
