ntppool.org Exporter

This exporter is @adoralaura s try to display server scores from servers in ntppool.org in a format which Prometheus can ingest.

Usage

Installation

Binaries can be downloaded soon from the GitLab releases page and need no special installation

Running

Start ntppool-exporter as a daemon or from CLI:

./ntppool-exporter

Visit http://localhost:43609/metrics?target=192.0.0.8 where 192.0.0.8 is the IP of the NTP server you want to get the score from.

Prometheus Configuration

The URL parameter target can be controlled through relabelling.

Example config:

scrape_configs:
  - job_name: 'ntppool'
    static_configs:
      - targets:
        - 192.168.1.2
        - 2003:db8::1
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 127.0.0.1:43609  # The ntppool exporter's real hostname:port.

Similarly to blackbox_exporter, ntppool-exporter is meant to run on a few central machines and can be thought of like a "Prometheus proxy".

TLS and basic authentication

The ntppool Exporter does not support TLS and basic authentication yet. This may be added in a future release.

Scaling

A single instance of ntppool-exporter should be able to query for a lot of servers. However, rate limits for upstream ntppool.org API endpoints may interfere. Furthermore, as this project is in its early stage, issues may currently prevent it from scaling.
