Managing the Webtrends Installation

Highlights system features for the administrator: topology, groups, and clusters.

Viewing Available Resources

The Topology dialog shows all the hosts, or computers, in your installation, the roles assigned to each host, and the available resources for each computer. A role is a function that the host performs according to the modules you installed on that computer. A group is a designation that you create primarily for the purpose of distributing work. To view the computers in your installation:

  1. In the left pane, click Administration > Application Settings > Monitoring > Topology .

Using Groups to Distribute Work

Webtrends allows you to create groups and assign the computers in your installation to those groups. For example, if you have multiple hosts that have the Standard Analysis Engine Role, you can use Host Groups to make sure that the computers that have sufficient system resources analyze your largest web activity data files. You could then assign profiles that process large data sets to this group. To work with host groups:

  1. In the left pane, click Administration > Application Settings > Host Groups .
  2. Click New to begin creating a new host group or edit an existing host group.

Managing Webtrends Services

For troubleshooting purposes, you may need to check the status of the Webtrends services. The Service Health dialog allows you manage all the Webtrends services in your installation through Webtrends Administration. To manage Webtrends services:

  1. In the left pane, click Administration > Application Settings > Monitoring > Service Health .

SQL Cluster Installation

Webtrends supports installation on a Microsoft SQL database cluster using Microsoft SQL 2008 Enterprise for the master database (wt_master and wt_sched), XMDB, and the Event database. Installing on a cluster can provide redundancy for your installation. SQL cluster environments are complex and require expert SQL knowledge. Extensive SQL cluster documentation is available from Microsoft and other sources.

To perform a SQL Cluster installation, you need:

  • A dedicated computer for each node in the SQL cluster.
  • A high-performance storage array network (SAN)

If you plan to install on a SQL cluster, you can use the standard distributed installation instructions for either Analytics or Visitor Data Mart, with the following modifications:

  1. When you install the first component in the distributed installation, which is always the master database, run the installation executable on a virtual machine that is NOT hosting the cluster from a command line using the ALLOW_CLUSTERING argument. For example:

    c:\msiv12\setup.exe ALLOW_CLUSTERING

  2. In the Master Database Connection dialog, select Use an existing SQL Server 2008 installation. For the Host field, specify the name of the SQL cluster. Use the virtual SQL server name, not the name of a node.
