| Parameter | Description |
|---|
| Server Session Start-Up Durations |
| Session ID | The unique ID for each user session. |
| Client IP | The IP address of the device connecting to a XenApp / Presentation Server. |
| Client Machine Name | The name of a device connecting to a XenApp / Presentation Server. |
| Logon Client User Name | The name of the user who is connecting to the XenApp / Presentation Server and accessing published application. |
| Credentials Authentication (in ms) | The Credentials Authentication Server Duration (CASD) is the time the application server spends authenticating the user's credentials against the authentication provider, which may be Kerberos, Active Directory, or a Security Support Provider Interface. |
| Credentials Obtention (in ms) | The Credentials Obtention Server Duration (COSD) is the time taken for the server to obtain the user credentials. Because this metric may be artificially inflated if a user fails to provide credentials in a timely manner, it is not included in the Session Start-up Server Duration (SSD). |
| Drive Mapping (in ms) | The Drive Mapping Server Duration (DMSD) is the time needed for the server to map the user's client drives, devices and ports. |
| Printer Creation (in ms) | The Printer Creation Server Duration (PCSD) is the time required for the server to synchronously map the user’s client printers. If the configuration is set such that printer creation is performed asynchronously, no value is recorded for PCSD as it is does not impact completion of the session start-up. |
| Profile Load (in ms) | The Profile Load Server Duration (PLSD) is the time required for the server to load the user’s profile. |
| Session Creation (in ms) | The Session Creation Server Duration (SCSD) is the time the server spends creating the session. This should not be confused with the overall SSD. |
| Session Startup (in ms) | The Session Startup Server Duration (SSSD) is the high-level server-side connection start-up metric that encompasses the time XenApp takes to perform the entire start-up operation. When an application starts in a shared session, this metric is normally much smaller than when starting a new session, which involves potentially high-cost tasks such as profile loading and login script execution. |
| Client Session Startup Durations |
| Session ID | The unique ID for each user session. |
| Client IP | The IP address of the device connecting to a XenApp / Presentation Server. |
| Client Machine Name | The name of a device connecting to a XenApp / Presentation Server. |
| Logon Client User Name | The name of the user who is connecting to the XenApp / Presentation Server and accessing published application. |
| Application Name | The name of the application user request to get session. |
| Application Enumeration (in ms) | The Application Enumeration Client Duration measures the time needed to retrieve the list of applications from the Web Interface service. Application enumeration is one of the issues slowing down session start times. |
| Back-Up URL Client Count | The BackUp URL Client Count (BUCC) is a recording of the number of back-up URL retries before a successful launch. This is the only start-up metric that is a measure of attempts, rather than time duration. If this metric has a value higher than 1, it indicates the Web Interface server is unavailable and the XenApp Plugin (formerly known as Program Neighborhood Agent) is attempting to connect to back-up Web Interface servers to launch the application. |
| Credentials Obtention (in ms) | The Credentials Obtention Client Duration (COCD) is the time it takes to obtain user credentials. Note: COCD is only measured when the credentials are entered manually by the user. Because this metric may be artificially inflated if a user fails to provide credentials in a timely manner, it is subtracted from the Startup Client Duration (SCD). This consideration is especially important if the metric is to be used for threshold alerting. |
| Configuration File Download (in ms) | The Configuration File Download Client Duration (CFDCD) is the time it takes to get the configuration file from the XML server. |
| ICA File Download (in ms) | The ICA File Download Duration (IFDCD) is the time it takes for the plugin (client) to download the ICA file from the server. Note: The overall process involved in downloading the ICA file is:- The user clicks on application icon.
- The user’s browser requests the Web Interface launch page.
- The Web Interface launch page receives the request and starts to process the launch, communicating with XenApp server and potentially other components such as Secure Ticket Authority (STA).
- The Web Interface generates ICA file data.
- The Web Interface sends the ICA file data back to the user’s browser.
- The browser passes ICA file data to the plugin (client). IFDCD metrics represents the time it takes for the complete process (step 1 to 6). Metric stops counting time when the client receives the ICA file data.
|
| Launch Page Web Server (in ms) | The Launch Page Web Server Duration (LPWD) metric is only used when Web Interface is the application launch mechanism. If LPWD is slow, there is a bottleneck on the Web Interface server.Process under this:- 1. The Web Interface launch page receives the request and starts to process the launch, communicating with XenApp server and potentially other components such as Secure Ticket Authority (STA).
- 2. The Web Interface generates ICA file data.
|
| Session Look-Up (in ms) | The Session Look Up Client Duration (SLCD) represents the time it takes to query every session to host the requested published application. The check is performed on the client to determine whether an existing session can handle the application launch request. The method used depends on whether the session is new or shared. |
| Session Creation (in ms) | The Session Creation Client Duration (SCCD) is the time it takes to create a new session, from the moment wfica32.exe is launched to when the connection is established. |
| Startup Client (in ms) | The Startup Client Duration (SCD) is a high-level client connection startup metric. It starts as close as possible to the time of the request (mouse click) and ends when the ICA connection between the client device and server running the XenApp / Presentation Server has been established. In the case of a shared session, this duration will normally be much smaller, as many of the setup costs associated with the creation of a new connection to the server are not incurred. |
