The global default is used only if it doesn't define its own scrape interval. Similarly, each alerting rule group defines its own evaluation interval. The global default is used only if it doesn't define its own evaluation interval.

You can create as many alerting rule groups as you like, and each rule group can have as many alerting rules as you like. Each alerting expression can access *all* the metrics in the TSDB - it is not tied to a specific scrape job. https://prometheus.io/docs/prometheus/latest/configuration/alerting_rules/ -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
