Monitoring

Monitoring allows you to visualize and quantify the performance and traffic of your projects on Vercel. You can use example queries or create custom queries to debug and optimize bandwidth, errors, performance, and bot traffic issues in a production or preview deployment.

Charts allow you to explore your query results in detail. Use filters to adjust the date, data granularity, and chart type (line or bar).

Hover and move your mouse across the chart to view your data at a specific point in time. For example, if the data granularity is set to 1 hour, each point in time will provide a one-hour summary.

To get started with the most common scenarios, use our Example Queries. You cannot edit or add new example queries. For a list of the available options, view our example queries docs.

You can save either personal (My Queries) or Team Queries from the left navigation bar. Personal queries can only be viewed and edited by the user who created them. Only team members with the owner or member roles can access team queries.

You can manage your saved personal and team queries from the query console. Select a query from the left navigation bar and click on the vertical ellipsis (⋮) in the upper right-hand corner. You can choose to Duplicate, Rename, or Delete the selected query from the dropdown menu.

Alternatively, you can perform the same actions from the left navigation bar. Hover your mouse over a saved query and click on the vertical ellipsis (⋮) to view the drop-down menu.

Duplicating a query creates a copy of the query in the same folder. You cannot copy queries to another folder. To rename a saved query, use the ellipses (⋮) drop-down menu or directly click its title to edit.

Deleting a saved personal or team query is permanent and irreversible. To delete a saved query, click the Delete button in the confirmation modal.

You may encounter errors such as invalid queries when using Monitoring. For example, defining an incorrect location parameter generates an invalid query. In such cases, no data appears.

Vercel creates events each time a request is made to your website. These events include unique parameters such as execution time and bandwidth used.

Certain events such as public_ip may be considered personal information under certain data protection laws. To hide IP addresses from your Monitoring queries:

1. Go to the Vercel dashboard and ensure your team is selected in the scope selector.
2. Go to the Settings tab and navigate to Security & Privacy.
3. Under IP Address Visibility, toggle the switch next to off so the text reads IP addresses are hidden in your Monitoring queries..
