How to Monitor Business Data Integrity Automatically

Your servers are up. Your APIs return 200. But is the data correct? A pricing error, a stale inventory count, or a broken report can cost more than downtime.

The Data Integrity Gap

Traditional monitoring stops at "is it up?" But businesses need to know:

• Are product prices correct?
• Does inventory match across systems?
• Are daily reports generating with correct data?
• Is the payment gateway returning valid responses?

NightPanel's Approach

NightPanel includes two checker types specifically designed for data validation:

Database Checker

Run SQL queries against your PostgreSQL database and assert conditions:

{
  "type": "database",
  "name": "Daily Revenue Check",
  "query": "SELECT sum(amount) as revenue FROM orders WHERE date = current_date",
  "assertion": "result.revenue > 0"
}

Integration Checker

Validate data from any REST API or file:

{
  "type": "integration",
  "name": "Product Price Validation",
  "url": "https://api.store.com/products/top-seller",
  "jmesPath": "price",
  "assertion": "value > 10 && value < 1000"
}

Real-World Examples

1. E-commerce: Verify that product prices haven't been accidentally zeroed out
2. Finance: Check that daily reconciliation reports have non-zero totals
3. Supply Chain: Confirm inventory counts are within expected ranges
4. SaaS: Validate that subscription counts match across billing and app databases

Getting Started

1. Sign up for NightPanel
2. Create a Database or Integration monitor
3. Set your assertion — the condition that must be true
4. Set the check interval (as low as 30 seconds on Enterprise)

If the assertion fails, your toolbar icon turns red immediately. No dashboard needed.
