The Health report in the Windows Dev Center dashboard lets you get data related to the performance and quality of your app, including crashes and unresponsive events. You can view this data in your dashboard, or download the report to view offline. Where applicable, you can view stack traces and/or CAB files for further debugging.
Alternatively, you can programmatically retrieve the data in this report by using the Microsoft Store analytics REST API.
Near the top of the page, you can select the time period for which you want to show data. The default selection is 72H (72 hours), but you can choose 30D instead to show data over the last 30 days. Note that data is shown in your local time zone for the 72H view and in UTC for the 30D view.
You can also expand Filters to filter all of the data on this page by package version, market, and/or device type.
- Package version: The default setting is All. If your app includes more than one package, you can choose a specific one here.
- Market: The default filter is All markets, but you can limit the data to one or more markets.
- Device type: The default setting is All, but you can choose to show data for only one specific device type. Note that the Other category includes devices where the make/model is recognized but we aren't able to include it into one of the pre-defined categories shown in this filter. For these devices, the device model can be viewed in the Failure log section of the Failure details report.
- OS version: The default is All OS versions, but you can choose a specific OS version.
- OS release version: The default is All OS release versions, but you can choose a specific release version of the selected OS version.
- Sandbox: The default is Retail, but for products that use multiple development sandboxes (such as games which integrate with Xbox Live), you can choose a specific one here. (If your product doesn't use sandboxes, this filter will show only Retail and won't be applicable.)
- Architecture: The default is All architectures, but you can choose a specific system architecture type. This filter is only available when 30D is selected.
- PRAID: The default setting is All, but if you defined multiple package relative app IDs (PRAIDs) when creating your app package, you can choose to show only data related to one PRAID. This filter will not appear if you have not defined multiple PRAIDs.
The info in all of the charts listed below will reflect the date range and any filters you've selected. Some sections also allow you to apply additional filters.
When the 30D time period is selected, you may see circle markers. These represent a significant increase or decrease in a given value that we think you'll want to know about. The date on which the circle appears represents the end of the week in which we detected a significant increase or decrease compared to the week before that. To see more details about what's changed, hover over the circle.
You can view more insights related to significant changes over the last 30 days in the Insights report.
Failure hits by market
The Failure hits by market chart shows the total number of crashes and events over the selected period of time by market.
You can view this data in a visual Map form, or toggle the setting to view it in Table form. Table form will show five markets at a time, sorted either alphabetically or by highest/lowest number of user sessions. You can also download the data to view info for all markets together.
The Package version chart shows the total number of crashes and events over the selected period of time by package version. By default, we show you the package version that had the most hits on top and continue downward from there. You can reverse this order by toggling the arrow in the Hits column of this chart.
The Failures chart shows the total number of crashes and events over the selected period of time by failure name. Each failure name is made up of four parts: one or more problem classes, an exception/bug check code, the name of the image/driver where the failure occurred, and the associated function name. By default, we show you the failure that had the most hits on top and continue downward from there. You can reverse this order by toggling the arrow in the Hits column of this chart. For each failure, we also show its percentage of the total number of failures.
At times, you may see an entry for Unknown in this section. This occurs when despite our best efforts, we are unable to collect full details for one or more failures, which will all be grouped together under Unknown. Most often, this occurs because of storage constraints, but it can also be a result of a device's privacy settings, network connection issues, partial/bad crash dumps, and other factors.
If you see !unknown as part of a failure name, this means that symbols weren’t present, so we couldn’t identify the failure name. Be sure to include symbols in your package to get accurate failure analysis. See Configure an app package. In contrast, failure names that include !unknown_error_in_ and !unknown_function mean that we weren’t able to gather complete details for various other reasons.
To display the Failure details report for a particular failure, select the failure name. If you have included symbol files, the Failure details report includes the number of failure hits over the last month, as well as a failure log that lists occurrence details (date, package version, device type, device model, OS build) and a link to the stack trace and/or CAB file, if available.
CAB files will only be available when the failure occurred on a computer using a Windows Insider build, so not all failures will include the CAB download option. To show only failures that have CAB files, select Failures with downloads in the section filter. You can also click the Links header in the Failure log to sort the results so that failures which include CAB files appear at the top of the list.
On the Failure details page, you'll also see the Stack prevalence chart, which shows the top stacks that contributed to the failure, ordered by percentage, and the Device configuration (30D) chart, which provides details about the configuration of devices which experienced the failure.
Crash-free sessions and devices (30D)
The Crash-free sessions and devices chart shows the percent of devices or user sessions that did not experience a crash in the past 30 days. This info helps you understand how broadly your crashes are affecting your users. For example, an app could have 10,000 crashes in one day. If 90% of your devices are affected, then you would probably classify that as critical and act to fix it right away. However, if that only represents 5% of devices using your app, the priority might be lower.
This chart has two tabs:
- Crash-free devices: Shows the percentage of unique devices that did not experience a failure on each day (during the past 30 days).
- Crash-free sessions: Shows the percentage of unique user sessions that did not experience a failure on each day (during the past 30 days).
