Telemetry Service

A standalone Go microservice that collects anonymous telemetry data from ProxmoxVE and ProxmoxVED script installations.

Overview

This service acts as a telemetry ingestion layer between the bash installation scripts and a PocketBase backend. When users run scripts from the ProxmoxVE/ProxmoxVED repositories, optional anonymous usage data is sent here for aggregation and analysis.

What gets collected:

• Script name and installation status (success/failed)
• Container/VM type and resource allocation (CPU, RAM, disk)
• OS type and version
• Proxmox VE version
• Anonymous session ID (randomly generated UUID)

What is NOT collected:

• IP addresses (not logged, not stored)
• Hostnames or domain names
• User credentials or personal information
• Hardware identifiers (MAC addresses, serial numbers)
• Network configuration or internal IPs
• Any data that could identify a person or system

What this enables:

• Understanding which scripts are most popular
• Identifying scripts with high failure rates
• Tracking resource allocation trends
• Improving script quality based on real-world data

Features

• Telemetry Ingestion - Receives and validates telemetry data from bash scripts
• PocketBase Integration - Stores data in PocketBase collections
• Rate Limiting - Configurable per-IP rate limiting to prevent abuse
• Caching - In-memory or Redis-backed caching support
• Email Alerts - SMTP-based alerts when failure rates exceed thresholds
• Dashboard - Built-in HTML dashboard for telemetry visualization

Dashboard

The built-in dashboard (/dashboard) provides real-time analytics:

• Installation Statistics - Total installs, success/failure rates
• Top Applications - Most installed scripts with counts
• Failure Analysis - Scripts with highest failure rates (min. 10 installs)
• Resource Trends - CPU, RAM, disk allocation over time
• OS Distribution - Popular operating systems
• Proxmox Versions - PVE version distribution

Dashboard Features:

• Automatic cache warmup (every 4 minutes)
• Configurable time range (7, 30, 90, 365 days)
• Shows actual total count vs. analyzed sample size
• Loading indicator during data fetch
