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: screenshot

Usage

  1. 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
    
  2. 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
