C++ Application Data Collection

After collecting application data to Guance, you can perform custom configuration scenarios and configure anomaly detection events through the Guance console.

Data Types

User access monitoring in Guance includes six types of data:

Type Description
session User session information records. In the current session, data related to user pages, resources, actions, errors, and long tasks are recorded based on the session dimension.
view A view record is generated each time a user visits an application page. When a user stays on the same page, resource, long task, error, and action records are linked to the relevant RUM view via the view_id attribute.
resource Records of resources loaded when the user accesses a page.
error Exceptions or crashes emitted by the application.
long_task For any task that blocks the main thread for more than a specified duration threshold in the application, a long task event is generated.
action Records user activities in the application (such as app startup, clicks, swipes, back actions, etc.). Each action is attached with a unique action_id.

Global Attributes

Scenarios for user access monitoring and event alerts can be queried using the following global attributes.

SDK Attributes

sdk_name string Collector name, fixed names:
df_macos_rum_sdk
df_linux_rum_sdk

sdk_version string Collector version information

Application Attributes

pre: pre-release environment
common: daily environment
local: local environment
version string Required, version number.
service string Optional, name of the associated business or service. Fixed names:

Custom Attributes

In addition to global attributes, custom attributes (SDK supports user-defined tag data) can be used to build scenarios and configure event alerts. Custom attributes are non-global attributes that allow tracking the entire process of user access to the application, identifying and discovering affected user visits, and monitoring user access performance.
