net_response

Example Input Plugin

The input plugin test UDP/TCP connections response time. It can also check response text.

Configuration:

# List of UDP/TCP connections you want to check
[[inputs.net_response]]
  protocol = "tcp"
  # Server address (default IP localhost)
  address = "github.com:80"
  # Set timeout (default 1.0)
  timeout = 1.0
  # Set read timeout (default 1.0)
  read_timeout = 1.0
  # String sent to the server
  send = "ssh"
  # Expected string in answer
  expect = "ssh"

[[inputs.net_response]]
  protocol = "tcp"
  address = ":80"

[[inputs.net_response]]
  protocol = "udp"
  # Server address (default IP localhost)
  address = "github.com:80"
  # Set timeout (default 1.0)
  timeout = 1.0
  # Set read timeout (default 1.0)
  read_timeout = 1.0
  # String sent to the server
  send = "ssh"
  # Expected string in answer
  expect = "ssh"

[[inputs.net_response]]
  protocol = "udp"
  address = "localhost:161"
  timeout = 2.0

Measurements & Fields:

• net_response
  • response_time (float, seconds)
  • string_found (bool) # Only if "expected: option is set

Tags:

• All measurements have the following tags:
  • server
