h4. Advanced AmazonCloudWatch configuration
If you need more control over the {{AmazonCloudWatch}} instance configuration you can create your own instance and refer to it from the URI:
{code}

from("direct:start")
.to("aws-cw://namepsace?amazonCwClient=#client");

{code}
The {{#client}} refers to a {{AmazonCloudWatch}} in the [Registry].

For example if your Camel Application is running behind a firewall:
{code}
AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

AmazonCloudWatch client = new AmazonCloudWatchClient(awsCredentials, clientConfiguration);

registry.bind("client", client);
{code}
