Alarm Configurations

Last updated: 2023-12-27 15:01:54


    Elastic MapReduce (EMR) has been connected to Cloud Monitor (CM). You can configure alarm policies for EMR nodes and service monitoring metrics in the CM console.
    EMR has been connected to CM's default alarms. CM will automatically create a default alarm policy. For information about metrics/events or alarm rules supported by the EMR default policy, see Default Alarm Policy.
    You can manually create an alarm policy and set it as the default alarm policy. After the default policy is set, newly purchased instances will be automatically associated with the default policy without requiring manual addition.

    2. On the Alarm Policy page, click Create.
