The beta phase of this feature has been concluded, and has reached general availability. This means that we now also support showing additional metrics, such as W3C navigation timings and Core Web Vitals for your transactions. You can find the additional metrics included in the transaction waterfall, in steps for which a waterfall has been enabled.
To enable the extra metrics for your transaction monitoring, select Chrome with extra metrics from the Browser type drop-down in the Advanced tab in the monitor settings. This feature will be available for Business- and Enterprise-level accounts only.
