# Monitor CodeBuild builds with CloudWatch
<a name="monitoring-builds"></a>

You can use Amazon CloudWatch to watch your builds, report when something is wrong, and take automatic actions when appropriate. You can monitor your builds at two levels: 

Project level  
These metrics are for all builds in the specified project. To see metrics for a project, specify `ProjectName` for the dimension in CloudWatch.

AWS account level  
These metrics are for all builds in an account. To see metrics at the AWS account level, do not enter a dimension in CloudWatch. Build resource utilization metrics are not available at the AWS account level.

CloudWatch metrics show the behavior of your builds over time. For example, you can monitor: 
+  How many builds were attempted in a build project or an AWS account over time. 
+  How many builds were successful in a build project or an AWS account over time. 
+  How many builds failed in a build project or an AWS account over time. 
+  How much time CodeBuild spent running builds in a build project or an AWS account over time. 
+ Build resource utilization for a build or an entire build project. Build resource utilization metrics include metrics such as CPU, memory, and storage utilization.
