Instance Method Details

This method returns a string suitable for inclusion in a page

  • known as ‘manual instrumentation’ for Real User

Monitoring. Can return either a script tag with associated javascript, or in the case of disabled Real User Monitoring, an empty string

This is the footer string - it should be placed as low in the page as is reasonably possible.

#browser_timing_header ⇒ Object

This method returns a string suitable for inclusion in a page

  • known as ‘manual instrumentation’ for Real User

Monitoring. Can return either a script tag with associated javascript, or in the case of disabled Real User Monitoring, an empty string

This is the header string - it should be placed as high in the page as is reasonably possible - that is, before any style or javascript inclusions, but after any header-related meta tags
