The VMware View Common Configuration ADMX (vdm_common.admx) template file contains policy settings common to all Horizon components. These templates contain only Computer Configuration settings.

Log Configuration Settings

The following table describes the log configuration policy setting in the VMware View Common Configuration ADMX template files. All of the settings are in the Computer Configuration > Policies > Administrative Templates > VMware View Common Configuration > Log Configuration folder in the Group Policy Management Editor.

Table 1. VMware View Common Configuration Template: Log Configuration Settings
Setting Properties
Log Directory Specifies the full path to the directory for log files. If the location is not writeable, the default location is used. For client log files, an extra directory with the client name is created.
Maximum debug log size in Megabytes Specifies the maximum size in megabytes that a debug log can reach before the log file is closed and a new log file is created.
Maximum number of debug logs Specifies the maximum number of debug log files to retain on the system. When a log file reaches its maximum size, no further entries are added and a new log file is created. When the number of previous log files reaches this value, the oldest log file is deleted.
Number of days to keep production logs Specifies the number of days for which log files are retained on the system. If no value is set, the default applies and log files are kept for seven days.
Send logs to a Syslog server Allows Horizon server logs to be sent to a Syslog server such as VMware vCenter Log Insight. Logs are sent from all Horizon servers in the OU or domain in which this GPO is configured.

You can send Horizon Agent logs to a Syslog server by enabling this setting in a GPO that is linked to an OU that contains your desktops.

To send log data to a Syslog server, enable this setting and specify the log level and the server's fully qualified domain name (FQDN) or IP address. You can specify an alternate port if you do not want to use default port 514. Separate each element in your specification with a vertical bar (|). Use the following syntax:

Log Level|Server FQDN or IP [|Port number(514 default)]

For example: Debug|192.0.2.2

Important: Syslog data is sent across the network without software-based encryption. Because Horizon server logs might contain sensitive data, avoid sending Syslog data on an insecure network. If possible, use link-layer security such as IPsec to prevent the possibility of this data being monitored on the network.

Performance Alarm Settings

VMware View Common Configuration Template: Performance Alarm Settings describe the performance alarm settings in the VMware View Common Configuration ADMX template files. All of the settings are in the Computer Configuration > Policies > Administrative Templates > VMware View Common Configuration > Performance Alarms folder in the Group Policy Management Editor.

Table 2. VMware View Common Configuration Template: Performance Alarm Settings
Setting Properties
CPU and Memory Sampling Interval in Seconds Specifies the CPU and memory polling interval CPU. A low sampling interval can result in an high level of output to the log.
Overall CPU usage percentage to issue log info Specifies the threshold at which the overall CPU use of the system is logged. When multiple processors are available, this percentage represents the combined usage.
Overall memory usage percentage to issue log info Specifies the threshold at which the overall committed system memory use is logged. Committed system memory is memory that has been allocated by processes and to which the operating system has committed physical memory or a page slot in the pagefile.
Process CPU usage percentage to issue log info Specifies the threshold at which the CPU usage of any individual process is logged.
Process memory usage percentage to issue log info Specifies the threshold at which the memory usage of any individual process is logged.
Process to check, comma separated name list allowing wild cards and exclusion Specifies a comma-separated list of queries that correspond to the name of one or more processes to be examined. You can filter the list by using wild cards within each query.
  • An asterisk (*) matches zero or more characters.
  • A question mark (?) matches exactly one character.
  • An exclamation mark (!) at the beginning of a query excludes any results produced by that query.

For example, the following query selects all processes starting with ws and excludes all processes ending with sys:

'!*sys,ws*'

Note: Performance alarm settings apply only to Connection Server and Horizon Agent systems. These settings do not apply to Horizon Client systems.

Security Settings

VMware View Common Configuration Template: Security Settings describe the security settings in the VMware View Common Configuration ADMX template files. All of the settings are in the Computer Configuration > Policies > Administrative Templates > VMware View Common Configuration > Security Settings folder in the Group Policy Management Editor.

Table 3. VMware View Common Configuration Template: Security Settings
Setting Properties
Only use cached revocation URLS Certificate revocation checking will only access cached URLs.

Default if not configured is false.

Revocation URL check timeout milliseconds The cumulative timeout across all revocation URL wire retrievals in milliseconds.

Not configured or value set to 0 means that Microsoft default handling is used.

Type of certificate revocation check Select the type of certificate revocation check to be done:
  • None
  • EndCertificateOnly
  • WholeChain
  • WholeChain

The default is WholeChainButRoot.

General Settings

VMware View Common Configuration Template: General Settings describes the general settings in the VMware View Common Configuration ADMX template files. All of the settings are in the Computer Configuration > Policies > Administrative Templates > VMware View Common Configuration folder in the Group Policy Management Editor.

Table 4. VMware View Common Configuration Template: General Settings
Setting Properties
Configure dump count on program error Limits the number of dump files that can be created. Set Maximum dump files to be created to any numerical value. The value takes effect per process and per process for each user. If you set the value to 0, no dump files are created. If you do not configure this setting, the number of dump files that can be created is 128 or unlimited, depending on the process that generates the dump files.
Configure dump type on program error Specifies the size of the dump files that can be created. Valid values are as follows:
  • Full - Produces a full dump. The dump contains the full memory of a process. The size of a full dump is relatively large.
  • Mini - The dump contains enough information to produce a stack trace and enable you to perform basic troubleshooting steps. The dump does not contain full memory, so you cannot extract information about some objects or object names. The size of the dump is relatively small.

If this setting is not configured, a full dump is created by default.
Disk threshold for log and events in Megabytes Specifies the minimum remaining disk space threshold for logs and events. If no value is specified, the default is 200. When the specified value is met, event logging stops.
Enable extended logging Determines whether trace and debug events are included in the log files.
Override the default View Windows event generation

The following values are supported:

  • 0 - Event log entries are only produced for view events (no event log entries are generated for log messages)
  • 1 - Event log entries are produced in 4.5 (and earlier) compatibility mode. Event log entries are not produced for standard view events. Event log entries are based solely on log file text.
  • 2 - Event log entries are produced in 4.5 (and earlier) compatibility mode with view events also being included.
