Diagnostics Window

The Diagnostics window, which is available in both the Designer and the Vision Client, contains a number of useful troubleshooting features. It features a number of tabs, some of which are initially hidden. Right-click on any of the visible tabs to show or hide other tabs.

Performance

Displays a number of small realtime charts that display various aspects of the currently executing Designer or Client's performance. These charts can be very useful to help troubleshoot performance issues, especially slow queries. One of the most common causes of query slowdown is simply running too many queries too frequently, and the # of Select Queries / Second chart can help identify when this is occurring.

Console

Displays the Output Console.

Log Viewer

Displays the logged events for the current Designer or Client session. Whenever errors occur, they will be logged and displayed in this tab. This is a good place to go when troubleshooting an issue, as any errors shown here may illuminate the cause of the problem. To view entries across all categories chronologically, uncheck the Group Categories checkbox.

Logging Levels

Determines the verbosity of a host of internal loggers. Most users will not use this tab unless prompted by a technical support representative.

Thread Viewer

Shows information about the currently running threads. Most users will not use this tab unless prompted by a technical support representative.
