# 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
- port
- protocol
### Example Output:
```
$ ./telegraf -config telegraf.conf -input-filter net_response -test
