🚀 Quick Start

Prerequisites

  • Elixir 1.15+
  • Erlang/OTP 26+
  • Phoenix 1.8+
  • SQLite

Installation

# Clone the repository
git clone https://github.com/your-org/flame_ping_monitor.git
cd flame_ping_monitor

# Install dependencies
mix setup

# Start the server
mix phx.server

Visit http://localhost:4000 to access the dashboard.

Adding Domains with Webhook Notifications

  1. Click “Add New Domain”
  2. Enter the domain URL (e.g., https://github.com)
  3. Optionally provide a display name
  4. Configure webhook URL for failure notifications (optional)
    • Example: https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK
    • Supports any HTTP endpoint that accepts JSON POST requests
  5. Click “Add Domain”

The system will automatically begin monitoring across all 5 regions with 10-second intervals. If 6 consecutive ping failures occur, a JSON notification will be sent to your webhook endpoint.

🔔 Webhook Notification System

JSON Payload Format

When 6 consecutive ping failures occur, the system sends this JSON payload:

{
  "domain": "https://example.com",
  "name": "My Website",
  "status": "critical_failure",
  "consecutive_failures": 6,
  "last_failure_at": "2024-01-15T10:30:00Z",
  "error_message": "Connection timeout",
  "timestamp": "2024-01-15T10:30:15Z"
}

Supported Integrations

  • Slack Webhooks: https://hooks.slack.com/services/...
  • Discord Webhooks: https://discord.com/api/webhooks/...
  • Microsoft Teams: https://outlook.office.com/webhook/...
  • PagerDuty Events API: https://events.pagerduty.com/v2/enqueue
  • Custom Endpoints: Any HTTP endpoint accepting JSON POST

Webhook Configuration

  1. Configure your webhook endpoint to accept HTTP POST requests
  2. Parse the JSON payload for failure details
  3. Implement your notification logic (Slack message, email, SMS, etc.)
  4. Return HTTP 200 status for successful delivery confirmation

🔧 Configuration

Environment Variables

# Database
DATABASE_URL="ecto://localhost/flame_ping_monitor_dev"

# Phoenix
SECRET_KEY_BASE="your-secret-key"
PHX_HOST="localhost"
PHX_PORT="4000"

# FLAME (Production)
FLAME_BACKEND="fly"
FLY_API_TOKEN="your-fly-token"

Ping Configuration

# lib/flame_ping_monitor/monitoring/ping_scheduler.ex
@ping_interval 10_000  # 10 seconds
@timeout 30_000       # 30 second timeout
@failure_threshold 6  # Webhook trigger threshold

🚀 Deployment

# Initialize Fly app
fly launch

# Deploy
fly deploy

# Set production secrets
fly secrets set SECRET_KEY_BASE=$(mix phx.gen.secret)
fly secrets set FLY_API_TOKEN="your-fly-api-token"

Note: This application is optimized for Fly.io deployment due to FLAME’s multi-region capabilities. For other platforms, you may need to modify the FLAME backend configuration.
