React Native Application Data Collection

Introduction

React Native data collection relies on the Android and iOS Native frameworks. To facilitate comparison with Android and iOS data collection, the items marked with strikethrough below are those not yet implemented.

Data Types

Guance Real User Monitoring (RUM) includes six data types.

Type Description
session Records user session information. Within the current session, access data related to user pages, resources, actions, errors, and long tasks is collected on a session dimension.
view Each time a user visits a page in the mobile application, a view record is generated. When the user stays on the same page, records for resources, long tasks, errors, and actions are linked to the relevant RUM view via the view_id attribute.
resource Records information about resources loaded when a user visits a page.
error Records exceptions or crashes raised by the mobile application.
long_task For any task that blocks the main thread for longer than a specified duration threshold in the application, a long task event is generated.
action Records user activity in the mobile application (e.g., app launch, tap, scroll, back). Each action is attached with a unique action_id.

Global Attributes

Both scenario construction and event alerting in RUM 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_ios_rum_sdk
df_android_rum_sdk
sdk_version string Collector version information

Application Attributes

Field Type Description
app_id string Required. The unique ID of the RUM application, automatically generated when creating a monitor in the Guance console.
env string Required. Environment field. Valid 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 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. A new session_id is generated after 15 minutes of inactivity.
session_type string Session type. Valid values: user & synthetics
user: Data generated by RUM functionality;
synthetics: Data generated by headless synthetic tests.
is_signin boolean Whether the user is a registered user. Valid values: T & F.

Device & Resolution Attributes

Field Type Description

Geographic & Network Attributes

Field Type Description

Custom Attributes

In addition to global attributes, you can also use custom attributes (the SDK supports custom tag data added by users) to build scenarios and configure event alerts. Custom attributes are non-global attributes. Using custom attributes, you can track the entire user visit process, locate and discover affected user visits, and monitor user visit performance.
