Enable AWS JAVA JVM Cloudwatch Metrics

Question

I'm trying to follow the instructions here.

I've added -Dcom.amazonaws.sdk.enableDefaultMetrics=cloudwatchRegion=eu-west-2 to the java options. I also added the following dependencies in the maven pom:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-cloudwatch</artifactId>
    <version>1.11.557</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-dynamodb</artifactId>
    <version>1.11.557</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-core</artifactId>
    <version>1.11.557</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-cloudwatchmetrics</artifactId>
    <version>1.11.557</version>
    <scope>provided</scope>
</dependency>

The docker container runs fine on an ec2 instance with the correct iam role and policies. However, there are no CloudWatch namespaces for AWS SDK/Java as the documentation suggests.

The docs state to use "-Dcom.amazonaws.sdk.enableDefaultMetrics" if you're running on EC2. However, this will only work if your EC2 instances have an IAM Role attached to them and that IAM Role must have permissions to call cloudwatch:PutMetricData. — mickzer

This uses another dependency, change the aws-java-sdk-cloudwatch to aws-java-sdk-cloudwatchmetrics.

<dependency>
  <groupId>com.amazonaws</groupId>
  <artifactId>aws-java-sdk-cloudwatchmetrics</artifactId>
  <version>1.11.557</version>
  <scope>provided</scope>
</dependency>
