What is this feature? This PR introduces a new alert rule configuration option, keep_firing_for (Prometheus documentation). keep_firing_for prevents alerts from resolving immediately after the alert condition returns to normal. Instead, they transition into a "Recovering" state and are not considered resolved by the Alertmanager. Once the recovery period ends (or after the next evaluation if it is bigger than keep_firing_for), the alert transitions to "Normal" if it doesn't start alerting again: Before +----------+ +----------+ | Alerting |---->| Normal | +----------+ +----------+ ----- After +----------+ +------------+ +----------+ | Alerting |----->| Recovering |---->| Normal | +----------+ +------------+ +----------+ Why do we need this feature? This feature prevents flapping alerts by adding a recovery period. This helps avoid false resolutions caused by brief alert
