CloudWatch events and metrics from Amazon EMR - Amazon EMR

Use events and metrics to track the activity and health of an Amazon EMR cluster. Events are useful for monitoring a specific occurrence within a cluster - for example, when a cluster changes state from starting to running. Metrics are useful to monitor a specific value - for example, the percentage of available disk space that HDFS is using within a cluster.

For more information about CloudWatch Events, see the Amazon CloudWatch Events User Guide. For more information about CloudWatch metrics, see Using Amazon CloudWatch metrics and Creating Amazon CloudWatch alarms in the Amazon CloudWatch User Guide.
