Critical App Faults User Guide

Overview

This DEX Pack Lite gives insight on which critical applications are the worst offenders for faults. A critical application is defined as an application in focus for more than five percent of the total application focus time, and it includes the top five critical apps per system.

How This Feature Helps You

The Critical App Faults DEX Pack is a diagnostic tool designed to help IT teams identify and address stability issues in key business applications. Here are the main benefits:

Identify Fault-Prone Applications

  • Highlights the top five critical applications per system that are most prone to faults.

  • A "critical application" is defined as one that is in focus for more than 5% of total application usage time.

Visualize Fault Trends

Provides pie charts and bar graphs showing:

  • Number of faults per application

  • Number of faulting systems

  • Number of faulting versions

Helps prioritize which applications need immediate attention.

Track Faults Over Time

  • Displays fault trends by date for specific application versions.

  • Useful for identifying whether issues are improving or worsening after updates or patches.

  • Drill Down into Fault Details

Offers detailed tables showing:

  • Fault combinations (for example, app version, module, fault address)

  • Systems affected by specific faults

  • Fault addresses and their frequency

Improve Application Stability

  • Enables proactive troubleshooting by pinpointing unstable app versions or configurations.

  • Reduces downtime and improves user experience by addressing root causes of crashes.

Customizable Filters

  • Allows filtering by system group, time frame, application, and version.

  • Makes it easy to focus on specific departments, teams, or time periods.

Global Filters

In the Global Filters section, you can select a group and a time frame for which to see the total faults and to populate the other sections on the page. The default for Group is All Systems. The default for Days is one week, which you can change to various durations from five days to one month. The Total Faults box adjusts to show you the total faults for the group and time frame that you select.

Faults per App

The Faults per App section displays a pie chart of applications and their faults. In the Display field, you can switch between three options:

  • Num Faults: This default option sets the chart to show the number of faults per application.

  • Num Faulting Systems: Select this option to set the chart to show the number of systems that have faulted per application.

  • Num Faulting Versions: Select this option to set the chart to show the number of application versions that have faulted per application.

Use the Application Search field in this section to limit the results to one application.

In the Display Top N Faulting Apps field, you can select to limit results to the top 10, 20, or 50 applications.

Hover over the pieces of the chart to see the details about each application. Click a piece of the chart to populate the other sections with that set of data.

Faults per App Version

This section shows a bar chart with the number of faults per application version. In the Display field, you can change the display to show the number of faulting systems per application version.

Hover over a bar in the chart to see exact numbers.

Selected Version Faults Over Time

This section shows a chart with the number of faults by date for the application version you selected. In the Display field, you can change the display to show the number of faulting systems per application version. In the Version to Display field, you can select to show all versions or just the version you selected.

Hover over a bar in the chart to see exact numbers.

Selected Version Systems

This section shows a table with all systems that experienced a fault for the application version you selected. In the Version to Display field, you can select to show all versions or just the version you selected.

Fault Combinations for Selected App

This section shows a table with details about fault combinations for the application you selected. For example, if you select Teams, you see a table with all Teams faults and their application version, module name, module version, fault address, fault count, first fault date, and last fault date.

Fault Address

This section shows a chart with the number of faults for each fault address for the application version you selected.
