API Monitoring and Health Checks for FileMaker Integrations

Beginner

Build lightweight monitoring for FileMaker Data API integrations: health check endpoints, latency tracking, alert thresholds, and error rate dashboards.

What you'll learn

How to implement a lightweight health check endpoint
How to measure and log API latency over time
How to detect and alert on elevated FileMaker error rates
How to distinguish FM application errors from infrastructure problems

FileMaker Server can throttle connections, run slow under heavy load, or fail silently when network issues arise. A monitoring layer that periodically exercises the API, tracks response times, and alerts on elevated error rates lets you catch problems before users do.

Health check endpoint pattern

Create an HTTP endpoint in your application that performs a minimal Data API call (e.g., fetch one record from a small layout) and returns a JSON summary with status and latency.

FileMaker Script

// GET /api/health/filemaker
export async function GET() {
  const start = Date.now();
  try {
    await fm.login();
    await fm.findRecords('HealthCheck', [{ Active: '1' }], { limit: 1 });
    await fm.logout();
    return Response.json({ status: 'ok', latencyMs: Date.now() - start });
  } catch (err) {
    return Response.json({ status: 'error', message: String(err) }, { status: 503 });
  }
}
