Value representing the number of times the synthetic transaction entity was down in a given time range.

For example, if the entity was down the entirety of the time range, the count would be 1.

Historical Overview. The amount of time in seconds that it took your synthetic transaction to complete its execution.

May be displayed as:

• Average Test Duration. Average time it took for your synthetic transaction to complete its execution.

Apdex score. A measurement of user satisfaction, using the Application Performance Index standard to specify the degree to which measured performance meets user expectations. The satisfactory load time, tolerating, and frustrated load times are defined when creating the website entity. For more information about the Apdex standard, Defining the Application Performance Index.

If the response time for requests takes less time than the satisfied load time threshold set for your website, the Apdex score is considered a satisfied load time. It is a tolerating load time if the response time takes up to four times the satisfied load time threshold, and a frustrated load time if it takes longer than four times the satisfied load time threshold.

Largest Contentful Paint. A measurement of how quickly the largest image or text content of a web page is loaded.

Largest contentful paint time is considered good if loading the largest image or text block takes less than 2.5 seconds, needs improvement if it takes up to 4.0 seconds, and poor if it takes longer than 4.0 seconds.

Interaction to Next Paint. A measurement of how quickly the website responds to user interactions such as clicks and key presses.

Interaction to next paint time is considered good if the response to a customer's first interaction with the website is below or at 200ms, needs improvement if it takes up to 500ms, and poor if it takes longer than 500ms.

Cumulative Layout Shift. Measures how much a webpage shifts unexpectedly while a user is viewing the webpage. A shift may occur if content loads at different speeds or if elements are added to the website dynamically.

A cumulative layout shift value of less than .1 is considered good, a value up to .25 needs improvement, and a value greater than .25 is poor.

First Input Delay. Time from when a user first interacts with your site to the time when the browser is able to respond to the interaction. First input delay (FID) helps measure the first impression a user has of your site's responsiveness.

The FID is considered good if responding to a customer’s first interaction with the site takes less than 100ms, needs improvement if it takes up to 300 ms, and poor if it takes longer than 300 ms.
