# Setting up Amazon CloudWatch alarms on Amazon Glue job profiles
<a name="monitor-profile-glue-job-cloudwatch-alarms"></a>

Amazon Glue metrics are also available in Amazon CloudWatch. You can set up alarms on any Amazon Glue metric for scheduled jobs. 

A few common scenarios for setting up alarms are as follows:
+ Jobs running out of memory (OOM): Set an alarm when the memory usage exceeds the normal average for either the driver or an executor for an Amazon Glue job.
+ Straggling executors: Set an alarm when the number of executors falls below a certain threshold for a large duration of time in an Amazon Glue job.
+ Data backlog or reprocessing: Compare the metrics from individual jobs in a workflow using a CloudWatch math expression. You can then trigger an alarm on the resulting expression value (such as the ratio of bytes written by a job and bytes read by a following job).

For detailed instructions on setting alarms, see [Create or Edit a CloudWatch Alarm](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ConsoleAlarms.html) in the *[Amazon CloudWatch Events User Guide](https://docs.amazonaws.cn/AmazonCloudWatch/latest/events/)*.
