Browser Compatibility
To start the Browser monitoring, apply the browser agent to the web application to collect. Before applying the browser agent, check the browser compatibility.
Collected data items for each browser version

To avoid overheads during session replay data collection, data is collected in idle time of the main thread. For this purpose, use the requestIdleCallback API. To avoid performance degradation, we have disabled collecting the session replay data on the browsers that do not support the requestIdleCallback API.
The requestIdleCallback API is designed to perform a callback when the browser is idle, making sure that it does not interfere with the main tasks while collecting the session replay data. For more information, see the following link.
