Configuration of AWSAmazonECSTest

For each AWS region, this test auto-discovers the clusters configured in that region and also the services running on each cluster. CPU and memory usage is then reported for each cluster and service, alongside the CPU and memory reservations (of all tasks) per cluster. These insights help administrators understand where there is a contention for resources - at the cluster-level? or at the service-level? or both? - and accordingly decide what needs to be done to optimize resource usage:

  • Should more container instances be added to the cluster to increase the amount of resources at its disposal?

  • Should the task definitions of the resource-hungry services be fine-tuned so that the service has more resources to use?

The default parameters associated with this test are:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • Specify the host for which the test is to be configured in the HOST text box.

  • To monitor an AWS EC2, the eG agent has to be configured with the "access key" of a user with a valid AWS account. To obtain the access key, follow the steps given below:

    • Sign up for a new AWS account from the http://aws.amazon.com/ec2/ page.

    • Provide the details of the user for whom you wish to create the AWS account.

    • Based on the AWS EC2 Regions, you will be requested to choose the pricing for an instance to be deployed in the AWS EC2.

    • Once the payment is made, the user will be automatically signed in to the AWS account.

    • From the newly created AWS account, you can request for an "access key". You will be provided with an "access key" and a corresponding “secret key”.

    • Provide the access key in the AWS ACCESS KEY text box; this will enable the eG agent to communicate with the AWS API and collect the required metrics.

  • Confirm the password by retyping it in the CONFIRM PASSWORD text box.

  • Provide the secret key corresponding to the access key that you had obtained through your AWS account in the AWS SECRET KEY text box.

  • In the EXCLUDE REGION box, you can provide a comma-separated list of region names or patterns of region names that you do not want to monitor. For instance, to exclude regions with names that contain ‘east’ and ‘west’ from monitoring, your specification should be: *east*,*west*

  • In some environments, all communication with the AWS EC2 cloud and its regions could be routed through a proxy server. In such environments, you should make sure that the eG agent connects to the cloud via the proxy server and collects metrics. To enable metrics collection via a proxy, specify the IP address of the proxy server and the port at which the server listens against the PROXY HOST and PROXY PORT parameters. By default, these parameters are set to none, indicating that the eG agent is not configured to communicate via a proxy, by default.

  • If the proxy server requires authentication, then, specify a valid proxy user name and password in the PROXY USER NAME and PROXY PASSWORD parameters, respectively. By default, these parameters are set to none, indicating that the proxy sever does not require authentication by default.

  • If a Windows NTLM proxy is to be configured for use, then additionally, you will have to configure the Windows domain name and the Windows workstation name required for the same against the PROXY DOMAIN and PROXY WORKSTATION parameters. If the environment does not support a Windows NTLM proxy, set these parameters to none.

  • By default, this test reports metrics for each cluster and for each service that is running on a cluster. Accordingly, ServiceName is the default selection from the ECS FILTER drop-down. If you do not want service-level metrics, then you can configure the test to report resource usage at the cluster-level alone. For this, just select ClusterName from the ECS FILTER drop-down. If this is done, then the test will only report cluster names as descriptors.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
