How do you monitor and observe Laravel integrations?

Every integration is instrumented with Laravel Pulse for performance metrics, Telescope for development tracing, and Sentry for error tracking. For production we add custom CloudWatch or Grafana dashboards tracking integration response times (P50, P95, P99), error rate per integration, queue depth for async work, and webhook delivery success rate. PagerDuty alerts fire on sustained integration failures or breached SLA windows. Every outbound request gets a correlation ID so we can trace a single business operation across multiple integration calls.
