定期探测网络是否成功

1. 构建 go build -ldflags="-s -w" ./cmd/healthcheck

2. 建立.env文件

   # 应用名称，默认使用当前pid
   APP_NAME=healthcheck
   # 写入指标日志的间隔时间，默认1s
   METRICS_INTERVAL=1s
   # 写入心跳日志的间隔时间，默认20s
   HB_INTERVAL=20s
   # Metrics对象的处理容量，默认1000，来不及处理时，超额扔弃处理
   CHAN_CAP=1000
   # 日志存放的目录，默认/tmp/log/metrics
   LOG_PATH=/var/log/footstone/metrics
   # 日志文件最大保留天数
   MAX_BACKUPS=7

3. 建立地址列表文件addr.txt

   192.168.126.16:22 测试机1
   192.168.126.18:22 测试机2
   

4. 运行程序

   healthcheck -interval=10s -f addr.txt

5. 查看输出
