Configuring Antivirus Software

By default, most antivirus programs are configured to scan all files on the hard disk. If an antivirus program
scans the frequently active Workload Balancing database, it impedes or slows down the normal operation
of Workload Balancing. Consequently, you must configure antivirus software running on your Workload
Balancing servers to exclude specific processes and files. Citrix recommends configuring your antivirus
software to exclude these folders before you initialize Workload Balancing and begin collecting data.
To configure antivirus software on the servers running Workload Balancing components:
• Exclude the following folder, which contains the Workload Balancing log:
On Windows XP and Windows Server 2003: C:\Documents and Settings\All Users\Application Data\Citrix
\Workload Balancing\Data\Logfile.log
On Windows Vista and Windows Server 2008: C:\Program Data\Citrix\Workload Balancing\Data
\Logfile.log.
• Exclude the SQL Server database folder. For example:
On SQL Server: C:\Program Files\Microsoft SQL Server\MSSQL\Data\
On SQL Server Express: C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL
\Data\
These paths may vary according to your operating system and SQL Server version.
Note:
These paths and file names are for 32-bit default installations. Use the values that apply to your installation.
For example, paths for 64-bit edition files might be in the C:\Program Files (x86) folder.
Configuring Workload Balancing Settings
After initialization, you can edit the Workload Balancing server connection settings and the settings Workload
Balancing uses to calculate placement and optimization recommendations.
Placement and optimization settings you can perform include changing the placement strategy, configuring
automatic optimizations and power management, editing performance thresholds and metric weightings,
and excluding hosts. You can also set up report subscriptions that generate and email reports to you on
a preset schedule automatically.
Workload Balancing settings apply collectively to all virtual machines and hosts in the pool. However, you
must configure individual settings for each resource pool in your environment.
Provided the network and disk thresholds align with the hardware in your environment, you might want to
consider using most of the defaults in Workload Balancing initially.
After Workload Balancing is enabled for a while, Citrix recommends evaluating your performance thresholds
and determining if you need to edit them. For example, consider if you are:
• Getting optimization recommendation when they are not yet required. If this is the case, try adjusting the
thresholds until Workload Balancing begins providing suitable optimization recommendations.
• Not getting recommendations when you think your network has insufficient bandwidth. If this is the
case, try lowering the network critical thresholds until Workload Balancing begins providing optimization
recommendations.
