📦 Deployment options
|
Deployment |
When to use |
|---|---|
|
The monitoring script can be deployed in the web application |
|
|

|
|
Deeper JavaScript execution analysis is required for selected diagnostic users |
|
|
Critical browser workflows must be tested proactively |
The precise coverage depends on the application architecture, browser security model, selected GermainUX component, browser capabilities, and configured privacy controls.
👁️ Real User Monitoring
GermainUX records authorized browser activity as users interact with the monitored application.
Depending on the configuration, collected activity can include:
|

|
Unavailable dependencies |
|
Requests associated with user-visible errors |
|
Network activity causing workflow delays |
Sensitive URLs, headers, query parameters, request bodies, response bodies, cookies, and tokens must be excluded or masked.
See Network Requests Monitoring.
⚙️ Server-Timing monitoring
When an application returns the standard Server-Timing response header, GermainUX can collect the metrics made available by the server.
These values can help divide an observed browser request into application-defined server stages, such as:
|
Examples |
|---|
|
Application processing |
|
Database activity |
|
Cache access |
|
External-service calls |
|
Rendering or preparation |
The browser can expose only the Server-Timing information returned by the application and permitted by cross-origin policies.

GermainUX can monitor supported WebSocket activity within instrumented browser applications.
Depending on configuration and browser access, insights can include:
|
Insights |
|---|
|
Connection opening and closing |
|
Connection duration |
|
Errors |
|
Message activity |
|
Customer-defined WebSocket events |

Activity associated with a user session or workflow |
WebSocket payload collection should be limited to data that is necessary and authorized.
See WebSocket Monitoring.
💬 Popup-dialog monitoring
GermainUX can detect native browser dialogs such as:
|
Type |
|---|
|
|
|
|
|
|
It can record when a dialog appears or closes and, when configured, measure how long it remained active.
Dialog content may contain sensitive business or personal data and should be masked or excluded when required.
🛡️ Browser reports and policy violations
Where supported by the browser, GermainUX can collect browser-reported events such as:
|
Details |
|---|
|
Content Security Policy violations |
|
Permissions Policy violations |
|

|
Browser and browser version |
|
Device and operating system |
|
Application version |
|
Activity preceding the termination |
|
Memory, errors, or long tasks observed before the event |
Browser security and lifecycle behavior prevent any browser-side monitor from detecting every possible process, operating-system, power, or network termination.
