You have to provide the amazonCwClient in the Registry or your accessKey and secretKey to access the Amazon's CloudWatch. |
|
If you need more control over the AmazonCloudWatch
instance configuration you can create your own instance and refer to it from the URI:
from("direct:start") .to("aws-cw://namepsace?amazonCwClient=#client"); |
The #client
refers to a AmazonCloudWatch
in the Registry.
For example if your Camel Application is running behind a firewall:
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); |
Maven users will need to add the following dependency to their pom.xml.
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-aws</artifactId> <version>${camel-version}</version> </dependency> |
where ${camel-version
} must be replaced by the actual version of Camel (2.10 or higher).
