fping-exporter

fping-exporter allows you to run measure network latency using fping and prometheus. Compared to blackbox-exporter, it gives you additionally latency distribution and a packet loss statistics. Also, it is probably better performing thanks to fping.

WARNING: This is currently a work in progress, the code is not production-ready yet

This graph shows the fping_rtt summary as "SmokePing"-like graph in Grafana:

Usage

Start fping-exporter as follows:

  fping-exporter [OPTIONS]

Application Options:
  -l, --listen=[HOST]:PORT    Listen address (default: :9605)
  -p, --period=SECS           Period in seconds, should match Prometheus scrape interval (default: 60)
  -f, --fping=PATH            Fping binary path (default: /usr/bin/fping)
  -c, --count=N               Number of pings to send at each period (default: 20)

Help Options:
  -h, --help                  Show this help message

Configure Prometheus to use this, as you would with blackbox-exporter. For example:

global:
  scrape_interval: 60s

scrape_configs:
  - job_name: test
    metrics_path: /probe
    static_configs:
    - targets:
      - "8.8.4.4"
      - "8.8.8.8"
    relabel_configs:
    - source_labels: [__address__]
      target_label: __param_target
    - source_labels: [__param_target]
      target_label: instance
    - target_label: __address__
      replacement: 127.0.0.1:9605  # The fping-exporter's real hostname:port.

Metrics

fping-exporter produces the following metrics:

fping_sent_count: Number of sent probes
fping_lost_count: Number of lost probes
fping_rtt_count: Number of measured latencies (successful probes)
fping_rtt_sum: Sum of measured latencies
fping_rtt: Summary of measured latencies
