Client Errors Detail table

Analyze client errors by different aspects. The dashlet provides different structure modes and filters in the tool bar of the dashlet . The following aggregation options are available:

  • Error: Aggregates errors according to the error message given by the browser or mobile application.
  • Client Type, Client Family: Groups all errors by client type (e.g. desktop browser, mobile browser, and mobile app) and client family with version or device information. For example, IE Mobile - IE Mobile 9.0, or Apple - iPod touch 4G. Another example is an error that occurred using Mozilla Firefox 6 is grouped under Desktop Browser - Firefox - Firefox 6.0.
  • Application: Groups errors by application.
  • Visit: All errors are grouped according to their visit within which it occurred.

Drill-Downs to other dashlets (e.g. User Actions Dashlet, User Action PurePaths Dashlet, and Visits Dashlet) are provided for deeper analysis.
