Measures reported by ViewSessionTest

By tracking the number and type of sessions to the VMware View connection broker, administrators can not only understand the load on their VMware View server, but can also determine how their VMware View licenses are being utilized. Such useful insights on load and license usage are provided by the ViewSessionTest test.

This test reports the total number of sessions on the VMware View server, and also reveals the number of sessions of each type currently active on the server. In addition, the test also highlights the maximum number of concurrent sessions of each type that were launched on the server. Based on these inputs, administrators can understand current license usage and can also plan future license requirements. The test also promptly alerts administrators to the impending expiry of the View license.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
All_sessions The number of View sessions currently active. Number This is a good indicator of the current session load on View.
Checkout_vms Indicates the current number of sessions in which VMs are checked out for use as local desktops. Number This measure will not be available from VMware Horizon View 6.0 onwards, as the ‘Local Mode’ feature has been deprecated from this version.

Compare the value of this measure with that of the Linked clone sessions measure to know what type of sessions are contributing to the current session load on the View server – full VM sessions? or linked-clone sessions?
Full_vms_sessions Indicates the current number of active full VM sessions. Number  
Clone_sessions Indicates the current number of active linked clone View sessions. Number A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation.

Compare the value of this measure with that of the Full_vms_sessions measure to know what type of sessions are contributing to the current session load on the View server – full VM sessions? or linked-clone sessions?
PCoIP_sessions Indicates the current number of PCoIP gateway sessions. Number In the event of a session overload, you can compare the value of these measures to know the type of sessions that is causing the overload.
Secure_sessions Indicates the current number of Secure gateway sessions. Number
Other_sessions Indicates the current number of active View sessions from other sources. Number
App_sesn Indicates the current number of active View application sessions. Number In the event of a session overload, you can compare the value of these measures to know the reason for the overload – is it because too many sessions are launching applications? Or is it many sessions are accessing desktops?
Desktop_sesn Indicates the current number of active View desktop sessions: Number
All_sesn_high Indicates the highest recorded number of concurrent View sessions. Number This is a good indicator of the maximum concurrent session load that the View server can handle. By observing the variations to this measure over time, you can understand the server capacity and accordingly plan its future resource requirements. The measure also indicates how concurrent licenses were utilized, and helps you determine whether/not more licenses will be required in the future.
Full_vm_sesn_high Indicates the highest recorded number of concurrent full VM sessions. Number If concurrent session load/usage of concurrent licenses is abnormally high, you can compare the value of this measure with that of the Link_cln_sesn_high to know the type of sessions that may have contributed the most to the erratic usage.
Link_cln_sesn_high Indicates the highest recorded number of concurrent linked-clone sessions. Number A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation.

If the value of the All_sesn_high measure is abnormally high, you can compare the value of this measure with that of the Full_vm_sesn_high to know the type of sessions that may have contributed the most to the erratic usage.
PCoIP_gtway_high Indicates the highest recorded number of concurrent PCoIP gateway sessions. Number If the value of the All_sesn_high measure is abnormally high, you can compare the value of these three measures to know the type of sessions that may have contributed the most to the erratic usage.
Sec_gtway_high Indicates the highest recorded number of concurrent secure gateway sessions. Number
Other_sesn_high Indicates the highest recorded number of concurrent sessions from other sources. Number
Appl_sesn_high Indicates the highest recorded number of concurrent application sessions. Number If the value of the All_sesn_high measure is abnormally high, you can compare the value of these two measures to know the type of sessions that may have contributed the most to the erratic usage.
Desktop_sesn_high Indicates the highest recorded number of concurrent desktop sessions. Number
Expirydate Indicates the number of days left for the VMware View license to expire. Number If an evaluation license is in use, this measure will report the number of days left for the license to expire. On the other hand, if a permanent license is obtained, a value Unlimited will be displayed indicating that the license will not expire at all.
Localdesktop Indicates whether the local mode license is enabled or not.   This measure will not be available from VMware Horizon View 6.0 onwards, as the ‘Local Mode’ feature has been deprecated from this version.

The idea behind Local Mode is to let VMware View users run virtual desktops while offline, giving them portability and the ability to run applications even when they are not connected to enterprise servers. That is ideal for supporting employees who travel with laptops, work with multiple PCs at different locations or do not have persistent access to a broadband connection.

This measure reports either Enabled or Disabled while indicating the status of the local mode license. The numeric values that correspond to the above-mentioned states are as follows:

State Numeric Value
Enabled 1
Disabled 0

Note:

By default, this measure reports the above-mentioned States while indicating the status of the local mode license. However, the graph of this measure will be represented using the corresponding numeric equivalents of the states as mentioned in the table above.
Viewcomposer Indicates whether the View Composer license is enabled or not.   This measure reports either Enabled or Disabled while indicating the status of the View Composer license. The numeric values that correspond to the above-mentioned states are as follows:

State Numeric Value
Enabled 1
Disabled 0

Note:

By default, this measure reports the above-mentioned States while indicating the status of the View Composer license. However, the graph of this measure will be represented using the corresponding numeric equivalents of the states as mentioned in the table above.
