Example 321a1ddfaf924803a075f1e69fc87bc06f53ccd0 | | DURATION | Type Number Description If the page completes loading, then DURATION indicates the duration of time in milliseconds between PAGE\_START\_TIME and when the loading completes. In this case, DURATION corresponds to EFFECTIVE\_PAGE\_TIME. If the page doesn't complete loading, then DURATION indicates the duration of time in milliseconds between PAGE\_START\_TIME and when the user navigates to another page. | | EFFECTIVE\_PAGE\_TIME | Type Double Description Indicates how many milliseconds it takes for the page to load before a user can interact with the page. Multiple factors can affect effective page time (EPT), such as network speed, hardware performance, or page complexity. | | EFFECTIVE\_PAGE\_TIME\_DEVIATION | Type Boolean Description When a deviation is detected, EFFECTIVE\_PAGE\_TIME\_DEVIATION records true. The default value is false. | | EFFECTIVE\_PAGE\_TIME\_DEVIATION\_ERROR\_TYPE | Type String Description Indicates the origin of an error. This field is populated when EFFECTIVE\_PAGE\_TIME\_DEVIATION\_REASON contains the PAGE\_HAS\_ERROR value.

Incomplete loading processes on a previous page can affect how the next page loads. - InteractionsBeforePageLoaded—A user interacts with a page element before the page is fully loaded. - PageInBackgroundBeforeLoaded—A background loading process runs on a page. Background processes run when a user navigates away from a page to another browser tab. The browser de-prioritizes the page in the background until the user activates the page’s tab. Because a user can leave a page in the background for a long time, the page is expected to have a high Effective Page Time (EPT). | | EVENT\_TYPE | Type String Description The type of event.

Some common fields, such as CPU_TIME and RUN_TIME, can have null or zero values depending on how the events are generated for a given feature. Sometimes, three quotation marks appear around event data containing special characters in the CSV file. The third quotation mark is necessary for tools and applications to parse the field data at the correct field value boundary.") - [EventLogFile](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_eventlogfile.htm "Represents event log files generated by Event Monitoring.
