prometheus-waze-exporter

Simple Prometheus exporter to monitor the travel distance and duration thanks to Waze API

Purpose

It has been made to monitor when is the best time to commute to avoid traffic jam.

Install

Having a working Golang environment:

go install github.com/trazfr/prometheus-waze-exporter@latest

Use

It performs a query to Waze to compute 2 main metrics:

• waze_travel_distance_meters
• waze_travel_time_seconds

It needs a configuration file to define which travel should be monitored.

To run it, just prometheus-waze-exporter config.json

Example of configuration file

config.json:

{
    "addresses": {
        "paris": "55 Rue du Faubourg Saint-Honoré, Paris, France",
        "versailles": "Place d'Armes, Versailles, France",
        "holidays": "Bormes-les-Mimosas, France"
    },
    "paths": [
        {
            "from": "paris",
            "to": "versailles"
        },
        {
            "from": "versailles",
            "to": "paris"
        },
        {
            "from": "paris",
            "to": "holidays"
        }
    ],
    "listen": ":9091",
    "region": "row",
    "vehicle": "taxi",
    "avoid_toll": true,
    "avoid_subscription_road": true,
    "avoid_ferry": true,
    "sleep": 500
}

• region may be:

  • us for the United States
  • il for Israel
  • row, this is the default value

• vehicle may be:

  • empty (""), it is a regular car. This is the default value if not defined
  • taxi
  • motorcycle

• avoid_toll, avoid_subscription_road and avoid_ferry are booleans. Their default value is false.

• sleep is an integer. It represents the number of milliseconds to wait between two calls to Waze API. Its default value is 500ms.

• listen is :9091 if unset, so you may configure in your scrape config if Prometheus is running on the same server:

- job_name: prometheus-waze-exporter
  scrape_timeout: 1m
  scrape_interval: 5m
  static_configs:
  - targets: ['127.0.0.1:9091']
