This is a summary of hardware and software requirements for small, medium and large Webtrends installations. The number of page views (Analytics) and events (Visitor Data Mart) determine the installation's size.

For all installations, note the following:

  1. Installation on a domain controller is not supported.
  2. All servers must reside on the same subnet and the same Windows domain.
  3. Do not store logs, analysis data, or report data, even temporarily, on the same drive as the operating system on a Webtrends computer. A minimum of two physical hard drives are required.
  4. Always allocate one processor core and 1GB of RAM to the operating system on any server, regardless of the Webtrends components installed on it.
  5. Usually, you can allow the operating system on each computer to allocate RAM to Webtrends components. The RAM recommendations provided for each installation size indicate the average amount of RAM that should be made available to each component.
  6. A gigabyte network is recommended for medium and larger installations.
  7. If installed to a virtual machine, both the RAM and CPUs need to be reserved for the Webtrends machine, and the limits set to match the reservations.

About Existing Installations and Hardware Scaling

If you have an existing installation of Webtrends software on hardware that does not meet the recommended configurations, the Webtrends installer will not prevent you from installing new versions of Webtrends software. However, if you encounter performance issues with a new installation on existing hardware, Webtrends support may recommend that you first upgrade your hardware to comply with minimum recommended hardware configurations.

As with any enterprise software, the recommended hardware configuration for running Webtrends software is likely to include more dedicated processing power and RAM as the application matures. The low cost of multi-core processors and RAM makes it sensible to install Webtrends software on computers that exceed the minimum recommended configuration. This makes it less likely that your organization will need to purchase new hardware as your use of the application increases.
## Storage and Memory Allocation Guidelines
Many factors influence storage requirements, including type of profile (Full analysis, Express, Visitor Data Mart) and complexity (number of custom reports or event tables, analysis limits). The following storage specifications are guidelines based on average usage and do not cover all usage ranges. The actual storage needed for your installation of Webtrends software may be different depending on the type and use of your installation. Storage should be managed so that there is ample free space on both the storage drive and the drive where analysis is occurring. Running out of hard drive space can corrupt your installation.

Storage Sizing Guidelines for Analytics

Page Views per day Per Profile Storage Guidelines
1.5-3 million page views 500 MB per profile for each year of data
10-15 million page views 1 GB per profile for each year of data
40-50 million page views 2 GB per profile for each year of data

For example, if you have 50 profiles that collect 100 million page views per day, your storage guideline is:
100 million page views / 50 profiles = 2 million page views per profile, per day
1 GB (twice the average for 2 MPV/day/profile) * 50 = 50 GB

Note:These figures do not include archiving of snapshots for backup purposes, which can quickly increase storage requirements. For example, if you keep 7 daily archives, 4 weekly, 1 monthly, 1 quarterly and 1 yearly, for your analytics data using default settings for archiving, you will need 15 times more storage than without archiving.

Virtualization

Webtrends supports installation of Webtrends software on the following virtualization products only:

VMWare ESX, versions 3.5 and above
VMWare ESXi, versions 3.5 and above

SDC may be run in a virtual environment with these characteristics:

  • Webtrends SDC On Premises v9.2.1 or higher
  • vSphere (VMWare and ESXi) v4.1 or 5.0
  • Virtual network adapter VMXNET 3 with default buffer settings
  • SmartSource Data Collector Hardware Requirements are fulfilled.

Webtrends does not support installation of Webtrends software on any other virtualization products, including the following:

  • Microsoft Hyper-V
  • VMware Workstation
  • VMware Fusion
  • VMware Server
  • VMware GSX Server
  • VMware Player

If you plan to install Webtrends on virtualization software, ensure that the virtualization environment complies with VMWare requirements and best practices for the hardware, and with the Webtrends system requirements (for example, reserved memory available within the image). Virtualization environments should be managed by a knowledgeable IT staff.

Webtrends Technical Support can assist with virtualized implementations as any other implementations. However, in cases where an issue cannot be reproduced by Technical Support, we may request a copy of your virtual environment and try to reproduce the issue using this image.

Webtrends and Anti-Virus Software

We recommend disabling anti-virus programs on your Webtrends servers because virus scanning can lock files that Webtrends needs. If the anti-virus program locks even a few files during a Webtrends analysis, Webtrends’ inability to write to these files can cause analysis to be incomplete and fail. Although the presence of anti-virus software does not guarantee a failure, running anti-virus and Webtrends on the same computer is not recommended.

Rather than disable virus scanning, you can configure the program not to scan log files, data files, or configuration files by excluding Webtrends directories. (Depending on your Webtrends installation, some of these files may be located on network drives or, in a distributed installation, on other computers.) Another option is to set your anti-virus program to run when Webtrends is not analyzing data, by turning off Webtrends services and then scanning.

Webtrends generates alerts based on whether anti-virus is running on the same computer as Webtrends. You can use the Alert Configuration dialog box to change the default response to anti-virus scanning. If you still have questions, please contact Webtrends Technical Support.
