View¶

You can view the user access environment, trace the user's operation path, analyze the response time of user operations, and understand the performance metrics of a series of call chains in the backend application caused by user operations.

In the View explorer, you can:

• Track user access data for each page, including load time, dwell time, etc.
• Combine data related to each page, such as resource requests, resource errors, and logs, to comprehensively analyze the performance of user access to business applications, helping to quickly discover and optimize code issues in applications.

Explorer List¶

In the View explorer, you can quickly view the page address, page load type, page load time, and user dwell time during user access.

Detail Page¶

Click on the data detail page you want to view in the list, and you can see the performance details of the user-accessed page, including attributes, source, performance details, trace details, error details, associated logs, etc.

Source¶

In Source, you can view the Session details of the current View, and filter/copy the current Session ID.

Performance¶

The Performance page helps you view the frontend page performance when a user accesses a specified application, including page load time, content rendering time, interaction time, input delay, etc. Taking the following figure as an example, you can see that the LCP (Largest Contentful Paint) metric reached 8.4 seconds, while the recommended time is within 2.5 seconds, indicating that the page loads slowly and needs optimization.

For events on the current page, you can choose to display the most recent 50, 100, 200 entries, or all entries:

Obsy AI Error Analysis¶

Guance provides the ability to parse error data with one click. It uses large models to automatically extract key information from the data, combines online search engines and an operations knowledge base, quickly analyzes possible fault causes, and provides preliminary solutions.

1. Click on a single data entry to expand the detail page.
2. Click "Obsy AI Error Analysis" in the upper right corner.
3. Begin the anomaly analysis.

Extended Fields¶

Attributes are the properties and characteristics of data objects, defining the value of each attribute.

In the search bar, you can enter a field name or value to quickly search and locate.

After checking the field alias, you can view it after the field name. You can choose as needed.

In the trace detail page, you can view the relevant field attributes of the current trace in Extended Fields:

Associated Fetch/XHR¶

When switching to Fetch/XHR, you can view each network request made to the backend application during user access, including the time of occurrence, the requested trace, and the duration.

If a network request has a corresponding trace_id, there will be a small icon prompt before the request. Clicking it will jump to the detail page of the corresponding trace.

Click on a data row, and you can choose to view the trace or resources related to that data:

Associated Errors¶

When switching to Errors, you can view the error data information, error type, and error occurrence time that appeared during this user access.

Click on the error message to jump to the detail page of the corresponding error.

For more error details, refer to the Error Explorer.

Associated Logs¶

Through Logs at the bottom of the detail page, you can view logs from the last 1 hour based on the current user access and the log count, and perform keyword searches, multi-tag filtering, and time sorting on these related logs.

• If you need to view more detailed log information: you can click on the log content to jump to the corresponding log detail page, or click Jump to Logs to view all logs related to this host.
• If you need to view more log fields or more complete log content: you can use the associated log explorer Display Columns to customize the Maximum display rows and Display Columns.

Note: For a smoother user query experience, Guance instantly saves the user's browsing settings in Logs (including "Maximum display rows" and "Display Columns") by default, so that Associated Logs remain consistent with Logs. However, custom adjustments made in Associated Logs are not saved after exiting the page.

Bind View¶

Guance supports setting binding or deleting built-in views (user views) to the detail page. Click Bind Built-in View to add a new view to the current detail page.

For more details, refer to the documentation Bind Built-in View.
