<div id="body32001227"><p id="aom_02_0953__en-us_topic_0000001261759891_p18142351600">By using suppression rules, you can suppress or block notifications related to specific alarms. For example, when a major alarm is generated, less severe alarms can be suppressed. Another example, when a node is faulty, all other alarms of the processes or containers on this node can be suppressed.</p>
