WEM Startup Details - OS Test

One of the common reasons for poor user logon experience in a Citrix XenDesktop environment is the delay in profile loading and group policy application. Using Citrix Workspace Environment Management (WEM), this delay can be greatly minimized!

Citrix WEM uses intelligent resource management and Profile Management technologies to provide the best logon experience to users in Citrix Hypervisor deployments.

Figure 1 depicts the architecture of Citrix WEM. The WEM Administration Console is where policies are defined and managed, resources are created and assigned, and users are authorized. The settings so defined are communicated to a WEM Broker, which stores the same in a SQL server backend. WEM Agents are deployed on VDAs or physical Windows devices. These agents communicate with the WEM Broker and enforce the settings you configured. An Active Directory server is used to push the settings to users.

Figure 2 : Architecture of Citrix WEM

Typically, the WEM agents offload the critical logon processing steps – eg., group policy application, logon script execution, drive/printer mapping, etc. – and perform them after the logon, thus significantly improving logon speed (see Figure 2).

Figure 3 : How Citrix WEM helps minimize logon time

This is why, where WEM is employed, user logons will be quick and hassle-free. However, if WEM clients – i.e., the WEM agents - experience delays or errors in logon processing, it can cause serious performance issues post logon. In other words, user profile loading, logon script execution, drive mapping etc., can become very slow. Because of such issues, a Citrix user will be unable to access the application/desktop profile, even after logging in quickly.

Therefore, to assure users of a high quality experience with Citrix at all times, administrators of WEM-enabled environments should continuously monitor the WEM processing times on the clients. This is exactly where the WEM Startup Details test helps!

For each user of a desktop OS machine that hosts a WEM agent, this test reports on the overall WEM processing duration, the time taken by the WEM agent to perform initial processing (this includes tasks such as detecting and reading initial configuration, reading SQL configuration, etc.), and the time taken by the WEM agent to perform main processing (this includes processing of main instructions - eg., mapping network/virtual drives, processing environmental variables, application launching etc.). In the process, administrators are proactively alerted to a delay in WEM processing. The root-cause of the delay is also accurately pinpointed - is it because WEM agent took too long to perform initial processing? or was too much time spent on processing the main instructions? if initial processing was delayed, then was the delay due to a bottleneck when the WEM agent was reading the initial configuration? or was it due to a delay when reading other settings such as SQL configuration, environmental settings, kiosk settings, etc.? if main processing was delayed, then was the delay because the WEM agent was slow detecting the OS/agent log settings? or was it owing to a delay in processing the critical instructions such as network drive mapping, virtual drive mapping, external task processing, application launching, etc? Errors in processing that could be slowing down WEM start-up are also highlighted, so that administrators can easily rectify them. This way, the WEM Startup Details - OS test promptly captures and reports performance bottlenecks on WEM clients that can impact overall user experience with the virtual server, thus prompting administrators to rapidly initiate remedial measures.

Target of the test : A Citrix Hypervisor VDI

Outputs of the test : One set of results for each user who is currently logged into the desktop OS machines hosting a WEM agent

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.
Port	The port at which the specified host listens. By default, this is NULL.
Xen User, Xen Password and Confirm Password	To enable the eG agent to connect to the XenServer API for collecting statistics of interest, this test should login to the target hypervisor as a root user. Provide the name of the root user in the Xen User text box. Root user privileges are mandatory when monitoring a XenServer 5.5 (or below). However, if you are monitoring XenServer 5.6 (or above) and you prefer not to expose the credentials of the root user, then, you have the option of configuring a user with pool-admin privileges as the Xen User. If you do not want to expose the credentials of a root/pool-admin user, then you can configure the tests with the credentials of a Xen User with Read-only privileges to the XenServer. However, if this is done, then the Xen Uptime test will not run, and the Xen CPU and Xen Memory tests will not be able to report metrics for the control domain descriptor. To avoid such an outcome, do the following before attempting to configure the eG tests with a Xen User who has Read-only privileges to the Citrix Hypervisor: Modify the target hypervisor's configuration in the eG Enterprise. For this, follow the Infrastructure -> Components -> Add/Modify menu sequence, pick Citrix Hypervisor as the Component type, and click the Modify button corresponding to the target hypervisor. In the MODIFY COMPONENT DETAILS page that then appears, make sure that the os is set to Xen and the Mode is set to SSH. Then, in the same page, proceed to provide the User and Password of a user who has the right to connect to the XenServer console via SSH. Then, click the Update button to save the changes. Once this is done, you can configure the eG tests with the credentials of a Xen User with Read-only privileges. The password of the specified Xen User needs to be mentioned in the Xen Password text box. Then, confirm the Xen Password by retyping it in the Confirm Password text box.
SSL	By default, the Citrix Hypervisor is not SSL-enabled. This indicates that by default, the eG agent communicates with the target hypervisor using HTTP. Accordingly, the SSL flag is set to No by default. If you configure the target hypervisor to use SSL, then make sure that the SSL flag is set to Yes, so that the eG agent communicates with the target hypervisor using HTTPS. Note that a default SSL certificate comes bundled with every Citrix Hypervisor installation. If you want the eG agent to use this default certificate for communicating with an SSL-enabled Citrix Hypervisor, then no additional configuration is required. However, if you do not want to use the default certificate, then you can generate a self-signed certificate for use by the target hypervisor. In such a case, you need to explicitly follow the broad steps given below to enable the eG agent to communicate with the target hypervisor via HTTPS: Obtain the server-certificate for the Citrix Hypervisor Import the server-certificate into the local certificate store of the eG agent For a detailed discussion on each of these steps, refer to the Troubleshooting section of this document.
Inside View Using	By default, this test communicates with every VM remotely and extracts “inside view” metrics. Therefore, by default, the Inside View Using flag is set to Remote connection to VM (Windows). Typically, to establish this remote connection with Windows VMs in particular, eG Enterprise requires that the eG agent be configured with domain administrator privileges. In high-security environments, where the IT staff might have reservations about exposing the credentials of their domain administrators, this approach to extracting “inside view” metrics might not be preferred. In such environments therefore, eG Enterprise provides administrators the option to deploy a piece of software called the eG VM Agent on every Windows VM; this VM agent allows the eG agent to collect “inside view” metrics from the Windows VMs without domain administrator rights. Refer to Configuring Windows Virtual Machines to Support the eG Agent’s Inside View Using the eG VM Agent for more details on the eG VM Agent. To ensure that the “inside view” of Windows VMs is obtained using the eG VM Agent, set the Inside View Using flag to eG VM Agent (Windows). Once this is done, you can set the Domain, Admin User, and Admin Password parameters to none.
Domain, Admin User, and Admin Password, and Confirm Password	By default, this test connects to each virtual guest remotely and attempts to collect “inside view” metrics. In order to obtain a remote connection, the test must be configured with user privileges that allow remote communication with the virtual guests. The first step towards this is to specify the DOMAIN within which the virtual guests reside. The ADMIN USER and ADMIN PASSWORD will change according to the DOMAIN specification. Discussed below are the different values that the DOMAIN parameter can take, and how they impact the ADMIN USER and ADMIN PASSWORD specifications: If the VMs belong to a single domain : If the guests belong to a specific domain, then specify the name of that domain against the DOMAIN parameter. In this case, any administrative user in that domain will have remote access to all the virtual guests. Therefore, an administrator account in the given domain can be provided in the ADMIN USER field and the corresponding password in the ADMIN PASSWORD field. Confirm the password by retyping it in the CONFIRM PASSWORD text box. If the guests do not belong to any domain (as in the case of Linux guests) : In this case, specify "none" in the DOMAIN field, and specify a local administrator account name in the ADMIN USER below. Prior to this, you need to ensure that the same local administrator account is available or is explicitly created on each of the virtual machines to be monitored. Then, proceed to provide the password of the ADMIN USER against ADMIN PASSWORD, and confirm the password by retyping it in the CONFIRM PASSWORD text box. If key-based authentication is implemented between the eG agent and the SSH daemon of a Linux guest, then, in the ADMIN USER text box, enter the name of the user whose <USER_HOME_DIR> (on that Linux guest) contains a .ssh directory with the public key file named authorized_keys. The ADMIN PASSWORD in this case will be the passphrase of the public key; the default public key file that is bundled with the eG agent takes the password eginnovations. Specify this as the ADMIN PASSWORD if you are using the default private/public key pair that is bundled with the eG agent to implement key-based authentication. On the other hand, if you are generating a new public/private key pair for this purpose, then use the passphrase that you provide while generating the pair. For the detailed procedure on Implementing Key-based Authentication refer to Troubleshooting the Failure of the eG Remote Agent to Connect to or Report Measures for Linux Guests. If the guests belong to different domains - In this case, you might want to provide multiple domain names. If this is done, then, to access the guests in every configured domain, the test should be configured with the required user privileges; this implies that along with multiple DOMAIN names, multiple ADMIN USER names and ADMIN PASSWORDs would also have to be provided. To help administrators provide these user details quickly and easily, the eG administrative interface embeds a special configuration page. To access this page, simply click on the Click here hyperlink that appears just above the parameters of this test in the test configuration page. To know how to use the special page, refer to Configuring Users for VM Monitoring. If the INSIDE VIEW USING flag is set to ‘eG VM Agent (Windows)’ - In this case, the inside view can be obtained without domain administrator privileges. Therefore, set the domain, admin user, and admin password parameters to none.
Ignore VMs Inside View	Administrators of some high security XenServer environments might not have permissions to internally monitor one/more VMs. The eG agent can be configured to not obtain the 'inside view' of such ‘inaccessible’ VMs using the IGNORE VMS INSIDE VIEW parameter. Against this parameter, you can provide a comma-separated list of VM names, or VM name patterns, for which the inside view need not be obtained. For instance, your IGNORE VMS INSIDE VIEW specification can be: xp,lin,win,vista. Here, the * (asterisk) is used to denote leading and trailing spaces (as the case may be). By default, this parameter is set to none indicating that the eG agent obtains the inside view of all VMs on a Citrix Hypervisor host by default. Note: While performing VM discovery, the eG agent will not discover the operating system of the VMs configured in the IGNORE VMS INSIDE VIEW text box.
Exclude VMs	Administrators of some virtualized environments may not want to monitor some of their less-critical VMs - for instance, VM templates - both from 'outside' and from 'inside'. The eG agent in this case can be configured to completely exclude such VMs from its monitoring purview. To achieve this, provide a comma-separated list of VMs to be excluded from monitoring in the EXCLUDE VMS text box. Instead of VMs, VM name patterns can also be provided here in a comma-separated list. For example, your EXCLUDE VMS specification can be: xp,lin,win,vista. Here, the * (asterisk) is used to denote leading and trailing spaces (as the case may be). By default, this parameter is set to none indicating that the eG agent obtains the inside and outside views of all VMs on a virtual host by default. By providing a comma-separated list of VMs/VM name patterns in the EXCLUDE VMS text box, you can make sure the eG agent stops collecting 'inside' and 'outside' view metrics for a configured set of VMs.
Ignore Winnt	By default, the eG agent does not support the inside view for VMs executing on Windows NT operating systems. Accordingly, the IGNORE WINNT flag is set to Yes by default.
Webport	By default, in most virtualized environments, the target hypervisor listens on port 80 (if not SSL-enabled) or on port 443 (if SSL-enabled). This implies that while monitoring an SSL-enabled Citrix hypervisor, the eG agent, by default, connects to port 443 of the server to pull out metrics, and while monitoring a non-SSL-enabled Citrix hypervisor, the eG agent connects to port 80. Accordingly, the webport parameter is set to 80 or 443 depending upon the status of the ssl flag. In some environments however, the default ports 80 or 443 might not apply. In such a case, against the webport parameter, you can specify the exact port at which the target hypervisor in your environment listens so that the eG agent communicates with that port.
Report by User	While monitoring a Citrix hypervisor, the REPORT BY USER flag is set to No by default, indicating that by default, the guest operating systems on the target hypervisor are identified using the host name specified in the operating system. On the other hand, while monitoring a Citrix hypervisor-VDI, this flag is set to Yes by default; this implies that in case of the Citrix hypervisor-VDI model, by default, the desktops will be identified using the login of the user who is accessing them. In other words, in VDI environments, this test will, by default, report measures for every username_on_virtualmachinename.
Report Powered OS	This flag becomes relevant only if the report by user flag is set to ‘Yes’. If the report powered os flag is set to Yes (which is the default setting), then this test will report measures for even those VMs that do not have any users logged in currently. Such guests will be identified by their virtualmachine name and not by the username_on_virtualmachinename. On the other hand, if the report powered os flag is set to No, then this test will not report measures for those VMs to which no users are logged in currently.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Information messages	Indicates the number of information messages logged in the event logs during WEM processing for this user.	Number
Warnings	Indicates the number of warning messages logged in the WEM logs during WEM processing for this user.	Number	Ideally, the value of this measure should be 0. If a non-zero value is reported, use the detailed diagnosis of this measure to view the warning messages logged in the WEM logs.
Errors	Indicates the number of errors messages logged in the logs during WEM processing for this user.	Number	Ideally, the value of this measure should be 0. A non-zero value is a cause for concern, as it indicates that one/more errors have occurred. You may want to use the detailed diagnosis of this measure to know what errors occurred.
Total WEM processing duration	Indicates the total time taken for WEM processing for this user.	Seconds	A consistent rise in the value of this measure could indicate a bottleneck in WEM processing for that user. To know where the bottleneck lies, compare the value of the Total init processing duration and WEM agent processing duration metrics. This will indicate where WEM agent spent maximum time - in starting up? or in post logon activities (eg., drive mapping, printer mapping, etc.)?
Total Init processing duration	Indicates the total time taken by WEM to perform initial processing for this user.	Seconds	The init processing duration is the time taken by the WEM agent to start-up. This includes the time taken by the WEM agent to detect the start-up settings and then read its configuration. If the value of this measure is abnormally high, it could indicate a delay in WEM agent start-up. To diagnose the root-cause of the delay, compare the value of all metrics grouped under the section Init Processing Breakup in the Layers tab page of the eG monitoring console. This will point you to where the bottleneck lies - did the agent take too long to detect start-up settings? did it take a long time to read the start-up configuration? or did the WEM agent experience any slowness when reading SQL configuration, Microsoft USV settings, environmental settings, system utilities settings, system monitoring settings, or kiosk settings?
WEM agent processing	Indicates the time taken by the WEM agent to perform post-logon activities for this user.	Seconds	The WEM agent processing duration is the sum of the time taken by the WEM agent to process the instructions it detected and read during the init processing/start-up stage, and the time taken to perform post-logon tasks such as virtual drives mapping, network drives mapping, registry entry processing, etc. If the value of this measure is abnormally high, it could indicate a delay in processing by the WEM agent. To diagnose the root-cause of the delay, compare the value of all metrics grouped under the section WEM Agent Processing Breakup in the Layers tab page of the eG monitoring console. This will point you to where the bottleneck lies - did the agent take too long to process the initial configuration it read? did it take a long time to map virtual drives / network drives? did processing of environment variables, registry entries, printers, ports, DNS, file system operations, file associations, or ini file operations take too long? was external task processing slow?
