Article
10/01/2024

Applies to

Windows 11, version 24H2

Required diagnostic data 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.

Required diagnostic data 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.

The following fields are available:

account_type A number representing the type of the signed in user account, where 0 indicates None, 1 indicates Microsoft Account, 2 indicates Azure Active Directory, 3 indicates On-Prem Active Directory and 4 indicates Azure Active Directory (Degraded). This field is currently only supported on mobile platforms and so the value is set to -1 on non-mobile platforms.
app_sample_rate A number representing how often the client sends telemetry, expressed as a percentage. Low values indicate that said client sends more events and high values indicate that said client sends fewer events.
app_version The internal Microsoft 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 wasn't 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).
AppSessionGuid An identifier of a particular application session starting at process creation time and persisting until process end.
brandCode Contains the 4 character brand code or distribution tag that has been assigned to a partner. Not every Windows install will have a brand code.
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 (for example, Canary/Dev/Beta/Stable). client_id isn't durable, based on user preferences. client_id is initialized 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.
device_sample_rate A number representing how often the device sends telemetry, expressed as a percentage. Low values indicate that device sends more events and high values indicate that device sends fewer events. The value is rounded to five significant figures for privacy reasons and if an error is hit in getting the device sample number value from the registry then this will be -1; and if client isn't on a UTC-enabled platform, then this value won't be set.
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.
experimentation_mode A number representing the value set for the ExperimentationAndConfigurationServiceControl group policy. See Microsoft Edge - Policies for more details on this policy.

PayloadClass The base class used to serialize and deserialize 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.
pop_sample A value indicating how the device's data is being sampled.
reactivationBrandCode Contains the 4 character reactivation brand code or distribution tag that has been assigned to a partner. Not every Windows install will have a brand code.
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.
utc_flags Event Tracing for Windows (ETW) flags required for the event as part of the data collection process.
