Balance exporter for Selectel service

The selectel balance exporter allows exporting balance for each service in selectel to prometheus

How it works

Exporter request balance every hour (by default) and store it value in memory. When prometheus request metrics, exporter send balance value from memory.

Configuration

You must set environment variable:

• SELECTEL_API_KEY - your api key. Api key can be generated at page https://my.selectel.ru/profile/apikeys

Command-line flags

• listen-address - The address to listen on for HTTP requests. (Default: 0.0.0.0:9600)
• interval - Interval (in seconds) for balance requests. (Default: 3600)
• retry-interval - Interval (in seconds) for load balance when errors. (Default: 10)
• retry-limit - Count of tries when error. (Default: 10)

# HELP balance_selectel Balance for service in selectel account
# TYPE balance_selectel gauge
balance_selectel{service="primary"} 10000.54

    -d \
    xxxcoltxxx/selectel-balance-exporter

services:
  selectel-balance-exporter:
    image: xxxcoltxxx/selectel-balance-exporter
    restart: unless-stopped
    environment:
      SELECTEL_API_KEY: <your-key>
    ports:
      - 9600:9600
