#Metrics and the live request log

Observability shows, for the chosen time range, requests, 4xx/5xx errors and error rate, response time (average, p50, p95, p99) and data transferred — for the whole project and per product (Data API, Auth, Storage, Edge Functions, Realtime). API Gateway breaks it down per service, so a slow or failing service stands out.

Observability → Request logs lists the latest 1,000 requests (method, path, status, service, duration) and updates live. Only the path is stored, never the query string, so tokens in URLs don't end up in logs.

#Log drains

A log drain forwards your project's logs to a tool you already use: every API request and every function run. Each line has a source of request or function. New lines are sent in batches within about 10 seconds, oldest first, and never twice. Add drains under Observability → Log drains.

Destinations must be public HTTPS hosts. After repeated failed deliveries (about 20 minutes) a drain pauses itself; fix the destination and resume it. Send test delivers one sample line.

import crypto from 'node:crypto'

export function verify(rawBody: Buffer, header: string | undefined, secret: string): boolean {
  const expected = 'sha256=' + crypto.createHmac('sha256', secret).update(rawBody).digest('hex')
  return !!header && header.length === expected.length && crypto.timingSafeEqual(Buffer.from(header), Buffer.from(expected))
}
