Domain exporter

This allows monitoring domain.com.au listings with Prometheus.

API Key

Grab an API key from https://developer.domain.com.au/. Make a project and add an API key. The free API keys only support 500 queries per day, so don't query often!

Building and running

Edit the searches in searches/*.json to be searches that look like the domain /v1/listings/residential/_search request schema.

$ go build .
$ ./domain_exporter --api_key=<domain api key>

Then navigate to http://localhost:10550/listings?suburb=Pyrmont

Building with docker

$ docker build .

Querying with Prometheus

Example Prometheus config for querying:

scrape_configs:
  - job_name: 'domain_exporter'
    static_configs:
      - targets:
        - 'domain_exporter:10550'
  - job_name: 'domain_exporter_listings'
    # Only 500 requests per day allowed, so don't query too often!
    scrape_interval: 2h
    metrics_path: "/listings"
    params:
      state: ["NSW"]
    # https://github.com/prometheus/prometheus/issues/4885#issuecomment-515144405
    static_configs:
      - targets:
        - Alexandria
        - Pyrmont
        - Glebe
        - Redfern
        - Newtown
        - Surry Hills
        - Ultimo
        - Waterloo
    relabel_configs:
      # Convert the 'targets' list given above to a ?suburb=Pyrmont URL param
      - source_labels: [__address__]
        target_label: __param_suburb
      # Send requests to the real hostname:port
      - target_label: __address__
        replacement: domain_exporter:10550

Caveats

• Domain API will only return a max of 1000 results per search. If you want more than that, consider splitting your search into multiple JSON files.
