Two major tools at your disposal for system health and monitoring are the Experience API logs, and system alerts.
Experience API logs
Our logs provide an in-depth overview of your server-side API calls, including events, pageviews, and choose calls. They enable you to verify that your API calls are correct and identify implementation issues. You can also use logs to troubleshoot unexpected behavior and find the root cause.
To access the API Logs, go to Settings › API Logs.
For details about working with API logs, see our Developer Docs.
Alerts
Alerts, which are displayed on your Experience OS dashboard, provide visibility into the health of your API implementation, enabling you to easily communicate ongoing implementation issues with your IT/R&D departments, and expedite the resolution of the underlying issues.
