Monitoring Amazon CodeBuild
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. - Amazon account level
-
These metrics are for all builds in an account. To see metrics at the Amazon account level, do not enter a dimension in CloudWatch. Build resource utilization metrics are not available at the Amazon 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 Amazon account over time.
-
How many builds were successful in a build project or an Amazon account over time.
-
How many builds failed in a build project or an Amazon account over time.
-
How much time CodeBuild spent running builds in a build project or an Amazon 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.
For more information, see Monitoring CodeBuild metrics.

CodeBuild CloudWatch dimensions
CodeBuild provides the following CloudWatch metric dimensions. If none of these are specified, the metrics are for the current Amazon account.
- BuildId, BuildNumber, ProjectName
-
Metrics are provided for a build identifier, build number, and project name.
- ProjectName
-
Metrics are provided for a project name.
CodeBuild CloudWatch alarms
You can use the CloudWatch console to create alarms based on CodeBuild metrics so you can react if something goes wrong with your builds. The two metrics that are most useful with alarms are:
-
FailedBuild
. You can create an alarm that is triggered when a certain number of failed builds are detected within a predetermined number of seconds. In CloudWatch, you specify the number of seconds and how many failed builds trigger an alarm. -
Duration
. You can create an alarm that is triggered when a build takes longer than expected. You specify how many seconds must elapse after a build is started and before a build is completed before the alarm is triggered.
For information about how to create alarms for CodeBuild metrics, see Monitoring builds with CloudWatch alarms. For more information about alarms, see Creating Amazon CloudWatch alarms in the Amazon CloudWatch User Guide.
