Mobile app stores Prometheus Exporter (iTunes & Google Play)

This Prometheus exporter exports metrics (score, ratings, reviews, app version, etc.) from Apple iTunes and Google Play

It's based on google-play-scraper and app-store-scraper to help getting the data from the mobile app stores.

I'm looking to add more stores in the future (Microsoft Store, Amazon Appstore, etc.)

Metrics supported by the exporter

Currently, the Prometheus Exporter exports these datas:

Metric	iTunes	Google Play
Score since first version	✅	✅
Current Version Score	✅	❌
Current Version number of Reviews	✅	❌
Total Number of Reviews	✅	✅
Total Number of Ratings	✅	✅
Total Number of Ratings with 1 star	✅	✅
Total Number of Ratings with 2 stars	✅	✅
Total Number of Ratings with 3 stars	✅	✅
Total Number of Ratings with 4 stars	✅	✅
Total Number of Ratings with 5 stars	✅	✅
Minimum Active Installs	❌	✅
Maximum Active Installs	❌	✅

Requirements

NodeJS >=18

Installation

Docker image

Default with demo apps

The simplest way to test this Prometheus exporter is by using Docker.

The command below will exports the metrics from the default apps from the src/examples/apps.json.

mkdir ./config
cp -R ./src/examples/*.json ./config

docker-compose up

Now, you can see the Prometheus metrics from your browser or command line at http://localhost:9514/metrics

curl http://localhost:9514/metrics

There is also a health check available which you can access from your browser or command line at http://localhost:9514/health

curl -v http://localhost:9514/health

Customize with yours apps

Now, try to test with your own app(s) by editing the config files.

Start by copy the files from the src/examples folder to the config folder (root of the project):

From		To
`src/examples/apps.json`	=>	`config/apps.json`
`src/examples/config.json`	=>	`config/config.json`

Add now your app IDs for iOS or/and Android on the apps.json file and activate the metrics you wants to export in the config.json file.

When it's done, restart the Docker container to see the changes:

docker-compose down
docker-compose up

curl http://localhost:9514/metrics

NPM install

From sources

git clone [email protected]:timoa/app-stores-prometheus-exporter.git
cd app-stores-prometheus-exporter
npm install

Copy the configuration files

From		To
`src/examples/apps.json`	=>	`config/apps.json`
`src/examples/config.json`	=>	`config/config.json`

mv ./src/examples/*.json ./config

Start the App Stores Prometheus Exporter:

npm start

The console will output this message:

Prometheus App Stores exporter is listening on http://localhost:9514

Prometheus configuration

To configure Prometheus to pull the data of the App Stores exporter, you just need to add this job to your prometheus.yml:

global:
[...]

scrape_configs:
  - job_name: 'appstores'
    scrape_interval: 5m

    static_configs:
      - targets:
        - localhost:9514

Scrape interval

Since the mobile app stores are using cache for the app details pages, it doesn't make sense to check the pages every 5s.

Depending of the number of apps you will monitor, it will be better to set the scrape interval to 5m or more.

Tests

API

You can launch the Docker container or node.js app and test the endpoints with Postman:

NPM

Unit-tests

npm test

Coverage

npm run test:coverage

Functional

npm run test:functional

All the tests

npm run test:all

Will be replace by chai-http soon.

Dashboards

The following Grafana dashboards are available in the Grafana Dashboards repository and can be install in your own Grafana instance (just copy the ID to import it):

TODO

Improve test coverage
Refactoring of the code to add more stores as plugins
Simplify multiple countries configuration
Add support to Mac App Store
Add support to Microsoft Store
Add support to Amazon Appstore
Add other metrics from official App Store and Google Play API (downloads, active installations, etc.)
