Example Input Plugin
The input plugin test UDP/TCP connections response time. It can also check response text.
Configuration:
[[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 the given string to the server and then
## expect to receive the given 'expect' string back.
## string sent to the server
# send = "ssh"
## expected string in answer
# expect = "ssh"
[[inputs.net_response]]
protocol = "tcp"
address = ":80"
# TCP or UDP 'ping' given url and collect response time in seconds
[[inputs.net_response]]
## Protocol, must be "tcp" or "udp"
protocol = "tcp"
## Server address (default localhost)
address = "github.com:80"
## Set timeout
timeout = "1s"
## Optional string sent to the server
send = "ssh"
## Optional expected string in answer
expect = "ssh"
## Set read timeout (only used if expecting a response)
read_timeout = "1s"
[[inputs.net_response]]
protocol = "udp"
address = "localhost:161"
timeout = "2s"
send = "hello server"
expect = "hello client"
