# Setting alarms on CloudWatch metrics from Amazon EMR
<a name="UsingEMR_ViewingMetrics_Alarm"></a>

Amazon EMR pushes metrics to Amazon CloudWatch. In response, you can use CloudWatch to set alarms on your Amazon EMR metrics. For example, you can configure an alarm in CloudWatch to send you an email any time the HDFS utilization rises above 80%. For detailed instructions, see [Create or edit a CloudWatch alarm](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ConsoleAlarms.html) in the *Amazon CloudWatch User Guide*.
