Create custom monitors in Vercel Observability Vercel launched custom monitors in Vercel Observability, letting teams trigger alerts from saved Observability queries on metrics such as AI Gateway costs, Core Web Vitals, Workflow and external API failure rates, and Vercel Sandbox CPU time. Each monitor tracks a single metric or a ratio of two, with statistical anomaly detection or a fixed threshold plus configurable detection windows, filters and grouping, and alerts route through email, Slack, Vercel Inbox, push notifications or team-level webhooks. Custom monitors are available on Pro and Enterprise plans with Observability Plus at $0.0035 per GB of data scanned, while built-in alerts remain included with Observability Plus. You can now create custom monitors to get alerts based on your Vercel Observability query https://vercel.com/docs/query results. For example, you can track signals such as AI Gateway costs, Core Web Vitals and other performance metrics, Workflow and external API failure rates, or Vercel Sandbox CPU time. Each monitor tracks a single metric, such as response time, or a ratio of two metrics, such as errors divided by total requests. Choose statistical anomaly detection or a fixed threshold, then configure the detection window, filters, and grouping. To create a monitor, inspect a chart’s query in Observability, start from a preset, or open Settings Alerts https://vercel.com/d?to=%2F%5Bteam%5D%2F%7E%2Fsettings%2Falerts%3FcustomAlert%3Dtrue for your team. Receive alerts through email, Slack, Vercel Inbox, push notifications, or team-level webhooks. You can also add context for Vercel Agent https://vercel.com/agent to use when investigating an alert. Custom monitors are available on Pro and Enterprise plans with Observability Plus, at $0.0035 per GB of data scanned. Built-in alerts remain included with Observability Plus.
