# Ping Input Plugin
Sends a ping message by executing the system ping command and reports the results.
Currently there is no support for GNU Inetutils, use with iputils-ping
instead:
```
apt-get install iputils-ping
```
### Configuration:
```toml
[[inputs.ping]]
## List of urls to ping
urls = ["example.org"]
## Number of pings to send per collection (ping -c <COUNT>)
# count = 1
## Interval, in s, at which to ping. 0 == default (ping -i <PING_INTERVAL>)
## Not available in Windows.
# ping_interval = 1.0
## Per-ping timeout, in s. 0 == no timeout (ping -W <TIMEOUT>)
# timeout = 1.0
## Total-ping deadline, in s. 0 == no deadline (ping -w <DEADLINE>)
# deadline = 10
## Interface or source address to send ping from (ping -I <INTERFACE/SRC_ADDR>)
## on Darwin and Freebsd only source address possible: (ping -S <SRC_ADDR>)
# interface = ""
## Specify the ping executable binary, default is "ping"
# binary = "ping"
## Arguments for ping command
## when arguments is not empty, other options (ping_interval, timeout, etc) will be ignored
# arguments = ["-c", "3"]
```
### Metrics:
- ping
- tags:
- url
- fields:
- packets_transmitted (integer)
- packets_received (integer)
- percent_packets_loss (float)
- average_response_ms (integer)
- minimum_response_ms (integer)
- maximum_response_ms (integer)
- standard_deviation_ms (integer, Not available on Windows)
- errors (float, Windows only)
- reply_received (integer, Windows only)
- percent_reply_loss (float, Windows only)
- result_code (int, success = 0, no such host = 1, ping error = 2)
##### reply_received vs packets_received
On Windows systems, "Destination net unreachable" reply will increment `packets_received` but not `reply_received`.
### Example Output:
**Windows:**
```
ping,url=example.org result_code=0i,average_response_ms=7i,maximum_response_ms=9i,minimum_response_ms=7i,packets_received=4i,packets_transmitted=4i,percent_packet_loss=0,percent_reply_loss=0,reply_received=4i 1469879119000000000
```
**Linux:**
```
ping,url=example.org average_response_ms=23.066,maximum_response_ms=24.64,minimum_response_ms=22.451,packets_received=5i,packets_transmitted=5i,percent_packet_loss=0,result_code=0i,standard_deviation_ms=0.809 1535747258000000000
