C++ Application Data Collection

After application data is collected into Guance, you can use the Guance console to customize scenarios and configure anomaly detection events.

Data Types

Guance's Real User Monitoring (RUM) includes six data types:

Type Description
session Records user session information. During a session, user page, resource, action, error, and long task access data are collected based on the session dimension.
view Each time a user visits a page in the application, a view record is generated. While the user stays on the same page, resource, long task, error, and action records are linked to the related RUM view via the view_id attribute.
resource Records information about resources loaded when a user visits a page.
error Exceptions or crashes emitted by the application.
long_task A long task event is generated for any task that blocks the main thread for longer than the specified duration threshold in the application.
action Records user activities in the application (app launch, click, swipe, back, etc.). Each action has a unique action_id.

Global Attributes

All RUM scenario building and event alerting can be queried using the following global attributes.

SDK Attributes

Field Type Description
sdk_name string Collector name, fixed values:
df_macos_rum_sdk
df_linux_rum_sdk
df_windows_rum_sdk
df_web_rum_sdk
df_miniapp_rum_sdk
df_ios_rum_sdk
df_android_rum_sdk
sdk_version string Collector version information

Application Attributes

Field Type Description
app_id string Required, the unique application ID for RUM, automatically generated when creating a monitor in the Guance console.
env string Required, environment field. Values: prod/gray/pre/common/local. Where:
prod: Production environment
gray: Canary environment
pre: Pre-release environment
common: Daily environment
local: Local environment
version string Required, version number.
service string Optional, the name of the business or service. Fixed values:
df_rum_ios
df_rum_android
df_rum_windows
df_rum_linux

User & Session Attributes

Field Type Description
userid string For unauthenticated users, a random UUID is used as the userid; for authenticated users, the user ID generated by the application backend is used.
user_name string Optional, user name.
user_email string Optional, user email.
session_id string Session ID. If there is no user activity for more than 15 minutes, a new session_id is generated.
session_type string Session type. Reference values: user & synthetics
user: Data generated by RUM features;
synthetics: Data generated by headless synthetic tests.
is_signin boolean Whether the user is a registered user. Values: T & F.

Custom Attributes

In addition to global attributes, you can also use custom attributes (the SDK supports user-defined custom tag data) to build scenarios and configure event alerts. Custom attributes are non-global attributes. Through custom attributes, you can track the entire user access process, locate and identify affected user access, and monitor user access performance.
