Available for the all views.
The Timeline is the primary focus of all Endpoint Agent views. It shows test data from the last 30 days, or the length of time the test has been enabled (whichever is the lesser value).
Timeline
The data shown on the timeline can be manipulated in a number of ways:
    By selecting the time range shortcuts (24h, 7d, 14d) in the top left corner of the timeline (to the left of the Metric Selector).
    By clicking within the timeline to select a particular round of data.
    By highlighting a range within the timeline.
    By using the Time Range Selector, described below.
Selecting a round or a time range will result in all views and tabs being updated to focus on that selection. This allows users to drill down into the data to focus on specific moments and issues in order to determine the cause of events.

Timeline Selector

Available for the all views.
The Timeline Selector allows users to customize the window the Timeline focuses on, by moving the highlighted section to the desired date, and increasing/reducing the size of the highlighted time range as necessary.
Timeline Selector
This area of focus can be between 24 hours and 14 days long. In the example image above, the range is between June 19th and June 25th, with the selected round occurring on June 22nd.

Additional Information

User Experience Score

The experience score rates a user's experience when loading a particular page. The score is calculated based on the time to load the DOM of a page, which is then mapped to a score based on our data set of load times. A score of 100 is the top score, 0 is the lowest score. An average experience is in the range of 44 to 89. Average (mean) experience scores can be displayed by Endpoint Agent, or by domain of pages visited.
The ThousandEyes experience score is based on formulas and values that are not all visible in the product. Generally speaking, the score depends on a correlation function of page availability and content speed. While direct validation from the platform view is not fully realizable from the endpoint display, some quantities are shown in the platform view. A detailed break down is shown below.

Experience Score

The experience score (ES) is determined by the following formula:
ES = max( 0, PAS - (100 - SS) )
    The max function is to ensure that the experience score (ES) is always limited between 0 and 100.
    The above formula allows future adding (or subtracting to be more accurate) impedances to the metric based on other factors (other than speed).
    The experience score is defined per page.
    PAS = Page availability score.
    SS = Speed score.

Page Availability Score

The page availability score (PAS) is a binary score indicating the presence of one of the following errors during page load:
    The server did not respond in time.
    A browser error prevented the page from loading.
    The server responded with an error (HTTP response code 4xx or 5xx).
    The server responded successfully (HTTP response code 200) but there was a browser error (e.g., loading an error page instead of the expected one).
    Page load is successful otherwise.
If an error occurs, PAS = 0. Otherwise, PAS = 100.
This is irrespective of the speed of the page (the speed score). It also does not consider component errors, at least for now.

Speed Score

The speed score is determined by the formula below:
SS = min( 0, 1 - ( ( Content Time + Redirect Time - X ) / Y ) ) )
    Content Time: Displayed in ms on the left side of the endpoint view.
    Redirect Time: Displayed in ms on the left side of the endpoint view. If it is 0 it is not shown.
    X and Y are based on the OnContentLoad time thresholds which are not visible in the display based on a linear correlation coefficient:
    Very Fast
    : OnContentLoad <= 1s
    → SS = 100
    → SS = 100
    Fast
    : 1s < OnContentLoad <= 2s
    → 89 <= SS < 100
    Average
    : 2s < OnContentLoad <= 6s
    → SS = 100-100*(CT-1)/(10-1)
    → 44 <= SS < 89
    Slow
    : 6s < OnContentLoad <= 10s
    → 0 < SS < 44
    Very Slow
    : 10s < OnContentLoad
    → SS = 0
    → SS = 0
