# Metric alerting and monitoring

Vercel's observability console now lets teams define their own alerting monitors from their own query results, not only from the built-in alerts that Observability Plus has provided. Each monitor tracks a single metric, such as response time, or a ratio of two, such as errors divided by total requests, and uses either statistical anomaly detection or a fixed threshold with a configurable detection window, filters and grouping. Monitors can be started from a chart query, a preset or the team's alerts settings, or defined in JSON and added with the CLI; alerts go to email, Slack or team webhooks, and the feature requires Observability Plus on Pro or Enterprise plans.
