Windows 10, version 1803 basic level Windows diagnostic events and fields

Article
05/24/2023

Applies to

Windows 10, version 1803

The Basic level gathers a limited set of information that is critical for understanding the device and its configuration including: basic device information, quality-related information, app compatibility, and Microsoft Store. When the level is set to Basic, it also includes the Security level information.

The Basic level helps to identify problems that can occur on a particular device hardware or software configuration. For example, it can help determine if crashes are more frequent on devices with a specific amount of memory or that are running a particular driver version. This helps Microsoft fix operating system or app problems.

Use this article to learn about diagnostic events, grouped by event area, and the fields within each event. A brief description is provided for each field. Every event generated includes common data, which collects device data.

Microsoft.Windows.FaultReporting.AppCrashEvent

This event sends data about crashes for both native and managed applications, to help keep Windows up to date. The data includes information about the crashing process and a summary of its exception record. It does not contain any Watson bucketing information. The bucketing information is recorded in a Windows Error Reporting (WER) event that is generated when the WER client reports the crash to the Watson service, and the WER event will contain the same ReportID (see field 14 of crash event, field 19 of WER event) as the crash event for the crash being reported. AppCrash is emitted once for each crash handled by WER (e.g. from an unhandled exception or FailFast or ReportException). Note that Generic Watson event types (e.g. from PLM) that may be considered crashes" by a user DO NOT emit this event.

The following fields are available:

AppName The name of the app that has crashed.
AppSessionGuid GUID made up of process ID and is used as a correlation vector for process instances in the telemetry backend.

Aria.f4a7d46e472049dfba756e11bdbbc08f.Microsoft.WebBrowser.SystemInfo.Config

The following fields are available:

app_version The internal Edge build version string, taken from the UMA metrics field system_profile.app_version.
appConsentState Bit flags describing consent for data collection on the machine or zero if the state was not retrieved. The following are true when the associated bit is set: consent was granted (0x1), consent was communicated at install (0x2), diagnostic data consent granted (0x20000), browsing data consent granted (0x40000).
Channel An integer indicating the channel of the installation (Canary or Dev).
client_id A unique identifier with which all other diagnostic client data is associated, taken from the UMA metrics provider. This ID is effectively unique per device, per OS user profile, per release channel (e.g. Canary/Dev/Beta/Stable). client_id is not durable, based on user preferences. client_id is initialised on the first application launch under each OS user profile. client_id is linkable, but not unique across devices or OS user profiles. client_id is reset whenever UMA data collection is disabled, or when the application is uninstalled.
ConnectionType The first reported type of network connection currently connected. This can be one of Unknown, Ethernet, WiFi, 2G, 3G, 4G, None, or Bluetooth.
container_client_id The client ID of the container, if in WDAG mode. This will be different from the UMA log client ID, which is the client ID of the host in WDAG mode.
container_session_id The session ID of the container, if in WDAG mode. This will be different from the UMA log session ID, which is the session ID of the host in WDAG mode.
Etag Etag is an identifier representing all service applied configurations and experiments for the current browser session. This field is left empty when Windows diagnostic level is set to Basic or lower or when consent for diagnostic data has been denied.
EventInfo.Level The minimum Windows diagnostic data level required for the event where 1 is basic, 2 is enhanced, and 3 is full.
install_date The date and time of the most recent installation in seconds since midnight on January 1, 1970 UTC, rounded down to the nearest hour.
installSource An enumeration representing the source of this installation: source was not retrieved (0), unspecified source (1), website installer (2), enterprise MSI (3), Windows update (4), Edge updater (5), scheduled or timed task (6, 7), uninstall (8), Edge about page (9), self-repair (10), other install command line (11), reserved (12), unknown source (13).
PayloadClass The base class used to serialise and de-serialise the Protobuf binary payload.
PayloadGUID A random identifier generated for each original monolithic Protobuf payload, before the payload is potentially broken up into manageably-sized chunks for transmission.
PayloadLogType The log type for the event correlating with 0 for unknown, 1 for stability, 2 for on-going, 3 for independent, 4 for UKM, or 5 for instance level.
session_id An identifier that is incremented each time the user launches the application, irrespective of any client_id changes. session_id is seeded during the initial installation of the application. session_id is effectively unique per client_id value. Several other internal identifier values, such as window or tab IDs, are only meaningful within a particular session. The session_id value is forgotten when the application is uninstalled, but not during an upgrade.
