During times of planned system disruptions, muting rules in New Relic Alerts can help filter out noisy notifications while maintaining observability and alerting on the rest of the system. Muting rules allow users to create conditions that match a large number of attributes and tags present in a violation event, overriding default life cycles to indicate that alerts should not send notifications. This enables users to minimize risks of overmuting by targeting specific subsets of their systems affected by planned disruptions, allowing them to observe when entities have recovered from maintenance and returned to a healthy state. Muting rules can be created and managed using either the New Relic Alerts UI or the NerdGraph API explorer, providing flexibility and automation for enterprise-scale issue detection and incident management.
