Known Issues

1. When the hardware NAT is enabled, the packet forwarding does not pass through the CPU, and the network speed statistics are inaccurate. If the hardware NAT is turned off, the performance will be degraded.(Reference) ;
2. Padavan's file system is immutable (TMPFS), so this program is currently running in SSH mode. That is, you need to run this program on other machines and connect to padavan through SSH;

Assets

这个exporter，是要docker-compose在哪个主机？

看日志，是要部署在padavan固件上，
但是，padavan不支持docker吧？

如果部署在去监控padavan的那个linux上，那我要去哪里修改ssh连接配置？谢谢。
