Telegraf监控客户端调研笔记（5）-本地端口监控&远程TCP探测

夜莺v4版本中有个端口监控功能，我们来看一下Telegraf如何实现这个功能。遍历了一下Telegraf的input plugin列表，看起来可以用net_response这个plugin来实现。该plugin配置如下：

# # Collect response time of a TCP or UDP connection# [[inputs.net_response]]#   ## Protocol, must be "tcp" or "udp"#   ## NOTE: because the "udp" protocol does not respond to requests, it requires#   ## a send/expect string pair (see below).#   protocol = "tcp"#   ## Server address (default localhost)#   address = "localhost:80"##   ## Set timeout#   # timeout = "1s"##   ## Set read timeout (only used if expecting a response)#   # read_timeout = "1s"##   ## The following options are required for UDP checks. For TCP, they are#   ## optional. The plugin will send
