AWS-EC2 Server Logins Test

This test attempts to connect to the default region in the cloud; in the process, the test reports whether the configured AWS user account is able to access the cloud-based infrastructure or not, and if so, how quickly the connection with the infrastructure was established.

If a user is denied access to a server instance on a clod, or if a user experiences a significant delay in connecting to his/her instances, you can use this test to validate the user credentials and to figure out whether any connectivity issues exist.

Target of the test: Amazon EC2 Cloud

Agent deploying the test: A remote agent

Output of the test: One set of results for the AWS EC2 Cloud being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

AWS Access Key, AWS Secret Key, Confirm AWS Access Key, Confirm AWS Secret Key

To monitor an Amazon EC2 instance, the eG agent has to be configured with the access key and secret key of a user with a valid AWS account. For this purpose, we recommend that you create a special user on the AWS cloud, obtain the access and secret keys of this user, and configure this test with these keys. The procedure for this has been detailed in the Obtaining an Access key and Secret key topic. Make sure you reconfirm the access and secret keys you provide here by retyping it in the corresponding Confirm text boxes.

Proxy Host and Proxy Port

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.

Proxy User Name, Proxy Password, and Confirm Password

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. Then, confirm the password by retyping it in the CONFIRM PASSWORD text box. By default, these parameters are set to none, indicating that the proxy sever does not require authentication by default.

Proxy Domain and Proxy Workstation

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.

Exclude Region

Here, 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*

Cloudwatch Enabled

This parameter only applies to the AWS - EC2 Aggregated Resource Usage test. This test reports critical metrics pertaining to the resource usage of the server instances launched in the cloud. If you want this test to report resource usage metrics very frequently - say, once every minute or lesser - you will have to configure the tests to use the AWS CloudWatch service. This is a paid web service that enables you to monitor, manage, and publish various metrics, as well as configure alarm actions based on data from metrics. To enable is test to use this service, set the CloudWatch Enabled flag to Yes. On the other hand, to report resource usage metrics less frequently - say, once in 5 minutes or more - this test does not require the AWS CloudWatch service; in this case therefore, set the cloudwatch enabled flag to No. Note that for enabling CloudWatch, you will have to pay CloudWatch fees. For the fee details, refer to the AWS EC2 web site.

Exclude Instance

This parameter applies only to AWS-EC2 Instance Connectivity, AWS-EC2 Instance Resources , and AWS-EC2 Instance Uptime tests. In the Exclude Instance text box, provide a comma-separated list of instance names or instance name patterns that you do not wish to monitor. For example: i-b0c3e*,*7dbe56d. By default, this parameter is set to none.

Measures reported by the test:

Measurement Description Measurement Unit Interpretation

Default region availability:

Indicates whether or not the test is able to access the default region on the cloud using the configured AWS user account .

Percent

The value 0 indicates that the region is not accessible, and the value 100 indicates that it is accessible. If the default region is inaccessible, it could be owing to any one of the following reasons:

  • The cloud is unavailable;
  • The configured AWS account does not have the access rights to the default region;
  • The test has been configured with incorrect login credentials. 

Response time:

Indicates the time taken by the test to establish a connection with the default region on the cloud.

Secs

A low value is desired for this measure. A high value or a consistent increase in this value could indicate connection bottlenecks.
