Webtrends Analytics 9 Adminstration Guide, November 2012
When you design a custom report, ask yourself how often, when, and from Webtrends should collect data, who will use reports, and how much data the report will generate.
Where will Webtrends Analytics 9 find the information you want to report on? If you want your site to record the information you need, you may need to set up custom tagging on your pages. Your custom reports may also depend on your configuring advanced features such as Content Groups and Scenario Analysis. When you choose dimensions, make sure you know how Webtrends tracks them.
How often and when should Webtrends Analytics 9 collect data? Some kinds of data give the same result for every hit during a visit. Others give a different result with every hit. Some measurements only make sense when collected once per visit. Think about what kinds of data you want to measure, and when Webtrends should measure them to get the most meaningful results.
Who will use the report? You can specify up to 32 different measures per custom report, but only a few of these may be relevant to the person who needs the report, and using many measures increases processing time and can affect performance. This question may also help you decide whether to use translation files, and give you guidance as you name your reports and report columns and as you provide Help text.
How much data will this report generate? Depending on the dimensions you choose and the structure of your data, you may encounter problems with very large table sizes that can affect performance. You may need to adjust table limits, filter your data very precisely, or reconsider your strategy for isolating the data that interests you.
