Client errors overview table

At the top of the Client Errors dashlet is an overview of the different error types. Additionally, a count indicates the number of errors that occurred within the specified time frame. The error types are:

  • Browser Errors

    • JavaScript Error: Errors, which occurred within the JavaScript code.
    • JavaScript Warning: Warnings captured by the JavaScript agent.
    • JavaScript Info: Such as exception messages.

    AppMon does not capture console.log() messages. You can use JavaScript ADK to get them.

  • Mobile Errors

    • Mobile Exceptions: Exceptions from mobile applications.
    • Mobile Error Codes: Error codes from mobile apps.
    • Mobile Crashes: Mobile crashes can contain a crash report, indicating the cause of the crash.

Selecting one or more error types from the overview table changes the details table's content.

Client Errors Detail table

Analyze client errors by different aspects. The dashlet provides different structure modes and filters in the toolbar 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 family and version or device information, and client type such as desktop browser, mobile browser, and mobile app. 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 like the User Actions dashlet, User Action PurePaths dashlet, and Visits dashlet) provide deeper analysis.
