Session Replay is compatible with page-based applications, single-page applications, and applications that use IFrames. However, certain restrictions apply.
The following technologies aren't supported:
- Shadow DOM
- Web components
- Plugins, such as Adobe Flash Player, Java applets, and non-HTML technologies
- Documents, such as PDF files and Word documents
- Pseudo CSS files
- Movie replay
- Traditional ASP (applications residing in the same environment as the monitored application must also not use traditional ASP)
IFrame and nested IFrame recording is supported. However, the following restrictions are applicable:
Session Replay doesn't store resources. It also can't reproduce blob/object URLs.
Restrictions for resources
- Resources must be available on the browser that's used for replay. There must be a direct connection to the server that serves the resources.
- Resources can't be protected. If resources are protected, ensure that they can be accessed by the player without requiring authentication.
- Resources can't be personalized. This is applicable to resources that are different for each user but are served by the same URL. However, the restriction doesn't apply to URLs that are different for each personalized resource. An example of this is avatar images that use the same URL to deliver different avatars for different users.
On average, a minute of session recording and replay consumes 100kB of storage space. This is also the required amount of upstream bandwidth from the client system to the Dynatrace servers that will be consumed. However, this value can't be guaranteed because it depends on the web application. Applications with very frequent DOM changes, big initial sizes, or heavy usage of IFrames can create large amounts of data.
Data transmission and OneAgent
Ensure that you're using OneAgent version 1.163 or above, because it supports a high volume of beacon transmission.
High volume beacon support is available for all Real User Monitoring capable agents:
Web applications are complex. While Session Replay is built to work with any web application and includes support for IFrames and single-page applications, there might be cases in which the reproduction of user interactions isn't perfect. For this reason, Session Replay may not recreate user experiences adequately for all web applications.
Session Replay must send data from client browsers to Dynatrace Server. Data transmission can fail depending on the environment, the available network connectivity, speed, network latency, connection problems, bandwidth, and other environment-related issues.
