Here are some common metrics defined in the Rigor app:
The time it takes for the server to respond to the initial request.
The time it takes for the user to first see the website.
The time it takes for the website to completely load all required page elements.
The Response Time for a single page Real Browser Check is the same as the Load Time. If a Real Browser Check has multiple steps then the Response Time equals the sum of Load Times for each page accessed during the user flow. The Response Time for an Uptime Check is equal to the Server Time.
For an Uptime Check, the Uptime metric represents the percentage uptime of an endpoint for a set time frame. For Real Browser Checks the Uptime percentage represents the percentage of time that the check passed within a set time frame.
The total size of all the files on the page (KB/MB).
The number of elements on the page, or the number of requests it takes to load the page.
Client, Server, or Connection errors that are fired during the page load (HTTP Response Code).
Total Load Time
The time it takes for the page to load all resources, including those that fire after the onload event. Note: Rigor displays the total load time on each waterfall chart, but does not save this metric for reporting or trending.
