# Monitoring CodeGuru Reviewer with Amazon CloudWatch
<a name="monitoring"></a>

You can use Amazon CloudWatch to monitor the number of recommendations created for your source code in an associated repository over time. 

The recommendations are available for three *dimensions*: 
+  `ProviderType` – View the number of recommendations for a provider type. You can view the count of recommendations in all repositories in AWS CodeCommit, your Bitbucket account, your GitHub account, or your GitHub Enterprise Server account, over a period of time. 
+  `CodeReviewType` – View the number of recommendations for a code review type. The one available code review type is `PullRequest`. Use it to view the count of recommendations in one pull request. 
+  `RepositoryName` – View the count of recommendations for one repository over a period of time. 

You can set a CloudWatch alarm that notifies you when the number of recommendations exceeds a threshold you set. 

For more information about creating and using CloudWatch alarms and metrics, see [Using Amazon CloudWatch alarms](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html). 

You can track the following metric for each dimension over a period of time.

# Monitoring CodeGuru Reviewer recommendations with CloudWatch alarms
<a name="cloudwatch-alarm"></a>

You can create an Amazon CloudWatch alarm for your CodeGuru Reviewer recommendations to monitor their count over time. 

An alarm watches the number of recommendations for one of three CodeGuru Reviewer CloudWatch dimensions that you specify: 
+  `ProviderType` – View the number of recommendations for a provider type. You can view the count of recommendations in all repositories in AWS CodeCommit, your Bitbucket account, your GitHub account, or your GitHub Enterprise Server account, over a period of time. 
+  `CodeReviewType` – View the number of recommendations for a code review type. The one available code review type is `PullRequest`. Use it to view the count of recommendations in one pull request. 
+  `RepositoryName` – View the count of recommendations for one repository over a period of time. 

You set one or more actions that happen when the number of recommendations for a dimension exceeds a count over a number of time periods you choose. For example, you can specify that an Amazon SNS notification is sent when more than 25 recommendations are generated for a branch in a repository within an hour. 

A user or role must have CloudWatch `PutMetricAlarm` permissions to create an alarm.
