Ping Input plugin

This input plugin will measures the round-trip

Configuration:

# NOTE: this plugin forks the ping command. You may need to set capabilities
# via setcap cap_net_raw+p /bin/ping
[[inputs.ping]]
## List of urls to ping
urls = ["www.google.com"] # required
## 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
## interface to send ping from (ping -I <INTERFACE>)
# interface = ""

Measurements & Fields:

  • packets_transmitted ( from ping output )
  • reply_received ( increasing only on valid metric from echo replay, eg. 'Destination net unreachable' reply will increment packets_received but not reply_received )
  • packets_received ( from ping output )
  • percent_reply_loss ( compute from packets_transmitted and reply_received )
  • percent_packets_loss ( compute from packets_transmitted and packets_received )
  • errors ( when host can not be found or wrong prameters is passed to application )
  • response time
    • average_response_ms ( compute from minimum_response_ms and maximum_response_ms )
    • minimum_response_ms ( from ping output )
    • maximum_response_ms ( from ping output )

Tags:

  • host
  • url

Example Output:

$ ./telegraf --config telegraf.conf --input-filter ping --test
