Configuring GermainUX Monitoring for ReactJS Applications

⚙️ Configure Monitoring for ReactJS

Configure GermainUX ReactJS monitoring to tailor Real User Monitoring, Session Replay, component analysis, errors, performance, JavaScript Profiling, network activity, privacy, analytics, SLAs, alerts, and automation.

⚙️ Access the ReactJS UX Monitoring Profile

Navigate to:

Germain Workspace → Settings → Analytics → UX Monitoring Profiles

Select the UX Monitoring Profile used by the ReactJS application.

The profile controls the browser-side monitoring behavior for the application.

🏷️ Configure the Application

Verify that monitored activity is associated with the correct application.

Use consistent application and environment names across:

• Production

• Staging

• Development

• Other monitored environments

Correct application identification is important for analytics and correlation with backend and infrastructure telemetry.

👤 Configure Real User Monitoring

Configure the actual-user telemetry required for the ReactJS application.

Depending on the monitoring objective, analyze:

• Sessions

• Navigation

• User actions

• Application activity

• Browser information

• Performance

• Errors

• Network requests

Enable only the telemetry required for the intended analysis.

🎥 Configure Session Replay

Session Replay is controlled by the ReactJS UX Monitoring Profile.

Navigate to:

Settings → Analytics → UX Monitoring Profiles → [ReactJS Profile]

Enable or disable:

Session Replay Monitoring

Session Replay can be configured to control:

• Whether sessions are recorded

• Session duration

• Session timeout

• User/session behavior

• Privacy

• Exclusions

• Timeline events

Use replay to investigate the context surrounding ReactJS performance, errors, and user friction.

⏱️ Configure Session Duration

Configure session behavior according to the application.

GermainUX supports settings such as:

settings.constants.maxSessionDurationMillis

to limit the maximum recording duration.

Session timeout can also be configured globally through:

Settings → System → UX and Session Replay Settings

👥 Configure Session Handling When Users Change

For environments where multiple users may authenticate through the same browser, configure:

settings.constants.createNewSessionIfUsernameChanges

Use:

settings.constants.createNewSessionIfUsernameChanges = true;

to create a new monitored session when the username changes.

🧩 Configure ReactJS Component Analysis

Configure analytics for ReactJS component activity captured from the application.

Use component analysis to identify:

• Component usage

• Rendering performance

• Slow-performing components

• Components associated with poor user experience

Analyze component performance together with the affected user session rather than in isolation.

⚡ Configure Performance Monitoring

Configure monitoring for browser and ReactJS performance conditions.

Analyze:

• User-perceived performance

• React component performance

• JavaScript execution

• Network response time

• Application responsiveness

Use performance KPIs and SLAs according to the expected application behavior.

🚨 Configure JavaScript Error Monitoring

Configure browser error collection for the ReactJS application.

Depending on the enabled RUM capabilities, monitor:

• JavaScript errors

• Unhandled errors

• Console errors

• Resource errors

• Application-specific errors

Correlate errors with:

• Application

• User

• Session

• Page

• User action

• Browser

• Network activity

This helps distinguish widespread issues from isolated errors.

🖥️ Configure Console Monitoring

Where console monitoring is required, configure the console information GermainUX should collect.

Use console telemetry to capture relevant:

• Errors

• Warnings

• Diagnostic messages

Avoid collecting unnecessary verbose console data in production.

⏳ Configure Long-Task Monitoring

Configure JavaScript long-task monitoring to identify execution that may block the browser's main thread and affect responsiveness.

Use the appropriate threshold for the application.

Long-task telemetry can help connect poor responsiveness with JavaScript execution occurring during the affected user interaction.

🔬 Configure JavaScript Profiling

For deeper JavaScript performance analysis, navigate to:

Settings → Analytics → UX Monitoring Profiles → [ReactJS Profile]

Enable:

JavaScript Profiling Monitoring

GermainUX supports JavaScript profiling through the available browser profiling mechanisms.

🔧 Configure JavaScript Profiling Parameters

Advanced profiling behavior is available through:

settings.plugins.jsProfiling

Configuration options include:

• functionMinStackHits

• maxSampleBufferSize

• maxProfileDuration

• profileOnPageReady

• sampleIntervalMillis

• useSelfProfilingAPI

• excludedUsernames

• includedUsernames

Use these settings only when the standard profiling configuration needs to be customized.

🌐 Configure Network & API Monitoring

Configure browser network monitoring for requests generated by the ReactJS application.

Analyze:

• Request URL or endpoint

• Response time

• Latency

• HTTP status

• Successful requests

• Failed requests

Network telemetry helps determine whether poor ReactJS experience originates in an API, service, or external integration.

🔗 Configure Integration Analysis

Associate relevant network and application telemetry with the integrations used by the ReactJS application.

Examples include:

• Backend APIs

• Authentication services

• Third-party services

• Payment services

• Search services
