-   * - Cumulative layout shift (CLS)
-     - ``synthetics.webvitals_cls.score``
-     - Measures page stability. CLS is based on a formula that tallies up how many times the components on the page move or “shift” around while the page is loading. Fewer shifts are better.

    * - Largest contentful paint (LCP)
      - ``synthetics.webvitals_lcp.time.ms``
      - Measures page loading times as perceived by users. The LCP metric reports the render time of the largest content element visible within the viewport.
 
    * - Total blocking time (TBT)
      - ``synthetics.webvitals_tbt.time.ms``
-     -  Captures issues that affect interactivity. TBT is a synthetic alternative for First Input Delay (INP), which measures page responsiveness to user input. Optimizations that improve TBT in the lab can also help improve INP for your users.
