Configuring Amazon CloudWatch support

Configure the appliance to send statistical data to Amazon CloudWatch so that this information can be used by the Amazon Elastic Load Balancer to handle the auto-scaling requirements of the environment.

About this task

To enable this service, configure the ec2.cloudwatch.frequency advanced tuning parameter to set how often the appliance sends the data to Amazon EC2.

To automate this configuration, use the deploy_isam_to_amazon_ec2.py script from the appliance File Downloads page.

The appliance can report memory, swap, and disk space usage metrics to Amazon CloudWatch.

If you already have an AWS Identity and Access Management role that is associated with your instance, make sure that it has permissions to perform the Amazon CloudWatch PutMetricData operation. Otherwise, you must create a new IAM role with permissions to perform CloudWatch operations and associate that role when you launch a new instance.

Procedure

In the appliance local management interface, go to Manage System Settings > System Settings > Advanced Tuning Parameters.
Click New.
Enter ec2.cloudwatch.frequency in the Key field.
In the Value field, set the frequency in minutes for the appliance to send statistical data to Amazon CloudWatch. A value of 0 disables the service.
Note: Monitor the system log for any errors that might occur when the appliance sends the data to CloudWatch.
Click Save Configuration.
Deploy the changes.
