Overview

The Stellar Account Prometheus Exporter retrieves account(s) balance and exposes it in prometheus format.

Configuration

Configuration file path must be provided using the --config option.

The config file is yaml formatted file:

networks:
- name: pubnet                              # Human readable name
  horizon_url: https://horizon.example.com  # Horizon URL
  accounts:
  - account_id: ABC123XYZ     # Account ID
    account_name: Account one # Human readable description
  - account_id: DEF456ABC
    account_name: Account two
- name: testnet
  horizon_url: https://horizon-testnet.example.com
  accounts:
  - account_id: QWE789DEF
    account_name: Testnet test account

By default the exporter listens on port 9618. This can be changes using --port switch or "PORT" environment variable.

Exported data

For each account the following metrics are exported:

• stellar_account_balance
• stellar_account_available_balance
• stellar_account_buying_liabilities
• stellar_account_selling_liabilities
• stellar_account_num_sponsored
• stellar_account_num_sponsoring
• stellar_account_scrape_success

Each metric has the following labels:

• network - network name from the configuration file
• account_id - account ID from the configuration file
• account_name - account name, as per configuration file
• asset_type - asset type

To download/test package in pypi you can use venv:

python3 -m pip install stellar_account_prometheus_exporter

./venv/bin/stellar-account-prometheus-exporter --config /path/to/config.yaml

Releasing new version

• ensure you bumped version number in setup.py. PyPi does not allow version reuse
• build new package:

python3 setup.py sdist bdist_wheel

• push to testpypi:

python3 -m twine upload --repository-url https://test.pypi.org/legacy/ dist/*

• test by installing the package (see above). If all good release:

python3 -m twine upload dist/*
