AWS Workspaces - Directory Test

An Amazon WorkSpace is a cloud-based virtual desktop that can act as a replacement for a traditional desktop. A WorkSpace is available as a bundle of compute resources, storage space, and software applications that allow a user to perform day-to-day tasks just like using a traditional desktop. A user can connect to a WorkSpace from any supported device using the free Amazon WorkSpaces client application, or using Chrome or Firefox web browsers. Users will connect using credentials set up by an administrator, or using their existing Active Directory credentials if you’ve chosen to integrate your Amazon WorkSpaces with an existing Active Directory domain. Once the user is connected to a WorkSpace they can perform all the usual tasks they would do on a desktop computer.

If a user is unable to connect to a Workspace or is experiencing considerable slowness when attempting to do so, that user will not be able to use the cloud resources effectively; this in turn will impact user productivity, hit revenues, and increase support costs and penalties.

To avoid this, administrators should be able to detect and resolve the unavailability/inaccessibility of Workspaces, and latencies in connecting to Workspaces, well before users complain. This is where the AWS Workspaces - Directory test helps!

This test automatically discovers the directories configured on the AWS Cloud for storing and managing information for Workspaces and users. For each directory so discovered, the test then reports the count of Workspaces in that directory in different states of activity - eg., available, unavailable, stopped, etc. This way, the test proactively alerts administrators to the abnormal state of Workspaces in a directory. In addition, the test also tracks connection attempts to the Workspaces in each directory, reports connection failures, and thus brings connection issues to the notice of administrators. The average time taken to launch sessions on the Workspaces in every directory is also reported, so that administrators can identify which directory is managing the most latent Workspaces.

Target of the test: Amazon EC2 Cloud

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each directory on the AWS EC2 cloud.

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*

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Available workspaces

Indicates the number of workspaces in this directory that returned a healthy status during the last measurement period.

Number

Amazon WorkSpaces periodically sends status requests to a WorkSpace. A WorkSpace is marked Available when it responds to these requests, and Unhealthy when it fails to respond to these requests.

Ideally, the value of this measure should be high.

Unhealthy workspaces

Indicates the number of WorkSpaces that returned an unhealthy status during the last measure period.

Number

Amazon WorkSpaces periodically sends status requests to a WorkSpace. A WorkSpace is marked Available when it responds to these requests, and Unhealthy when it fails to respond to these requests.

Ideally, the value of this measure should be low.

Connection attempt

Indicates the number of connection attempts made to workspaces in this directory during the last measure period.

Number

Connection success

Indicates the number of connection attempts made to workspaces in this directory that were successful during the last measure period.

Number

Ideally, the value of this measure should be equal to the value of the 'Connection attempt' measure. If the difference between the two measures is very high, it implies that many connections have failed.

Connection failure

Indicates the number of connection attempts to the workspaces in this directory that failed during the last measurement period.

Number

Ideally, the value of this measure should be 0. A value close to or equal to the value of the Connection attempt measure denotes many failed connection attempts, which is a cause for concern.

Session latency

Indicates the average round trip time between the WorkSpaces client and the WorkSpaces in this directory during the measure period.

Secs

This measure is reported after a user has successfully authenticated via the WorkSpaces client and the client then initiates a session. Any delay in authentication and/or session initiation can cause the value of this measure to increase. If you notice abnormal spikes in the value of this measure, then you may want to compare the value of this measure with that of the Session launch time measure to know where the latency is maximum - at the time of authentication? or during session initiation?

Session launch time

Indicates the average time for initiating sessions with the Workspaces in this directory.

Secs

If you notice abnormal spikes in the value of this measure, then you may want to compare the value of this measure with that of the Session latency measure to know where the latency is maximum - at the time of authentication? or during session initiation?

Session disconnect

Indicates the number of connections with Workspaces in this directory that were closed during the last measure period.

Number

The value of this measure also includes user-initiated and failed connections.

Ideally, the value of this measure should be 0.

User connected workspaces

Indicates the number of Workspaces in this directory that had a user connected during the last measurement period.

Number

Amazon WorkSpaces periodically sends connection status requests to a WorkSpace. Users are reported as connected when they are actively using their sessions.

Stopped workspaces

Indicates the number of Workspaces in this directory that stopped during the last measurement period.

Number

Workspaces in maintenance

Indicates the number of Workspaces in this directory that were under maintenance during the last measurement period.

Number

This metric applies to WorkSpaces that are configured with an AutoStop running mode. With this mode, your WorkSpaces stop after a specified period of inactivity and the state of apps and data is saved.

Amazon WorkSpaces schedules maintenance for your WorkSpaces. During the maintenance window, important updates are downloaded and installed. If you enable maintenance mode for your AutoStop WorkSpaces, they are started automatically once a month in order to download and install important service, security, and Windows updates.
