If you already monitor your web frontends with RUM Classic, upgrading to the New RUM Experience requires only a configuration change. This guide outlines the prerequisites and necessary steps.

Prerequisites

Before enabling the New RUM Experience, make sure the following conditions are met.

Required to enable the setting

  • RUM Classic is enabled.
  • The RUM JavaScript version is RUM JavaScript version 1.317+.
  • The snippet format code snippet, which is not supported by the New RUM Experience, isn't used. For alternatives, see Recommendations for selecting the snippet format.

Required to capture and ingest data

  • The OneAgent version is OneAgent version 1.301+.
  • Because new features are added regularly, we recommend keeping both OneAgent and the RUM JavaScript up to date. The RUM JavaScript version should be configured to either Latest stable or Previous stable, as described in Configure the RUM JavaScript version for a frontend.

If you use automatic injection, the new configuration is applied within 5 minutes. If you insert the RUM JavaScript manually, you may need to update the snippet, depending on the snippet format you’re using:

  • JavaScript tag: The new configuration is applied automatically, but it may not take effect immediately due to caching. The file that contains the monitoring code and configuration is cached for one hour on the Dynatrace CDN. Additionally, browsers respect the configured cache duration.
  • OneAgent JavaScript tag, OneAgent JavaScript tag with SRI or inline code: As with any configuration change, you need to update the inserted snippet.
