Prometheus style "smokeping" prober.

Example Graph


This prober sends a series of ICMP (or UDP) pings to a target and records the responses in Prometheus histogram metrics.

usage: smokeping_prober [<flags>] [<hosts>...]

  -h, --help                     Show context-sensitive help (also try --help-long and --help-man).
      --config.file=CONFIG.FILE  Optional smokeping_prober configuration yaml file.
                                 Address on which to expose metrics and web interface.
                                 Path under which to expose metrics.
                                Path to config yaml file that can enable TLS
                                 A comma delimited list of buckets to use
  -i, --ping.interval=1s         Ping interval duration
      --privileged               Run in privileged ICMP mode
  -s, --ping.size=56             Ping packet size in bytes
      --log.level=info           Only log messages with the given severity or above. One of: [debug, info, warn,
      --log.format=logfmt        Output format of log messages. One of: [logfmt, json]
      --version                  Show application version.

  [<hosts>]  List of hosts to ping


The prober can take a list of targets and parameters from the command line or from a yaml config file.

Example config:

- hosts:
  - host1
  - host2
  interval: 1s # Duration, Default 1s.
  network: ip # One of ip, ip4, ip6. Default: ip (automatic IPv4/IPv6)
  protocol: icmp # One of icmp, udp. Default: icmp (Requires privileged operation)
  size: 56 # Packet data size in bytes. Default 56 (Range: 24 - 65535)

In each host group the interval, network, and protocol are optional.

The interval Duration is in Go time.ParseDuration() syntax.

NOTE: The config is only read on startup, SIGHUP is not supported (yet).
