# 2 小时综合长测（task-3 第 1、3 项）。
#
# 同时测四件事，并且都带**时间戳**，这样才能回答
# "失败是不是集中在某个时段"（运营商时段性抖动）：
#
#   1. 公网可用率    每 15 秒一次 /v1/health，连续 2 小时
#   2. 长轮询成功率  30 次真实 poll（每次挂 60 秒），后台跑
#   3. 连接数波动    每 60 秒采样两个 metrics 端口
#   4. 重连/拨号失败 从两个 tunnel 日志的事件增量算
#
# 输出:
#   /root/long2h_health.tsv   时间戳 状态码 耗时ms
#   /root/long2h_poll.tsv     序号 状态码 耗时ms 起始时间
#   /root/long2h_conns.tsv    时间戳 quic连接 http2连接
#   /root/long2h_summary.txt  汇总
