世界上最简单的监控服务 pingd
pingd 是世界上最简单的监控服务，使用 golang 编写。软件支持 IPv6，但是服务器不支持。
pingd 允许同时 ping 上千个 IPs，在此期间还可以管理监控的主机。
用户提供主机名或者 IP，还有用户邮箱地址，就可以使用 3 个生成 URLs 来开启，停止或者删除你的追踪。每当你的服务器停机或者后台在线都会发送通知，还包含控制 URLs。
~$# start monitoring your server with a single curl command. ~$curl ping.gg/me@example.org/104.28.13.51 [ ok ] Ping alert created for host '104.28.13.51' and email 'me@example.org'. Check your email to activate it. ~$# activate the first and the next ones are activated automatically. ~$curl ping.gg/me@example.org/example.org [ ok ] Ping alert created for host 'example.org' and email 'me@example.org'. ~$# you can skip the IP if you run it from the server, watch out for proxies, etc. ~$curl ping.gg/me@example.org [ ok ] Ping alert created for host '104.28.12.51' (your IP) and email 'me@example.org'.

# get the example export GOPATH=$PWD go get github.com/pinggg/pingd/examples/httpmail # start pinging 8.8.8.8 and 8.8.4.4 and email you if they go down sudo bin/httpmail -email=mymail@example.org 8.8.8.8 8.8.4.4 # add a new host while running curl localhost:7700/4.4.2.2 # stop pinging 8.8.4.4 curl -XDELETE localhost:7700/8.8.4.4
