The Records Module provides the most granular view of system performance by showing every step of the interaction between the test node (or user) and the server(s).
A RUM Record represents a single pageview by a real user. Each record contains detailed metrics for each file requested as part of the pageview. The records module provides a waterfall representation of the selected record, which shows all of the requests on a timeline, enabling you to see exactly how long each process took, and which steps might be creating bottlenecks or causing other performance issues.
To access Records, click on the Analysis module 
in the main menu and select Records.
The Records UI consists of the following sections:
Source
This is the specific App that you are analyzing.
Session
This refers to the specific user session that generated the pageview(s) you will be analyzing.
During the session, the user might have connected to one or more pages within you App. Each connection is considered a unique Pageview, and generates its own Record. You can see a list of all Pageviews from the selected Session in the "Pages Visited" section.
You can select a different Pageview by clicking the corresponding Radio Button here, and this will update the rest of the Records screen with data from that Pageview.
To select a pageview from a different Session, click the "Change Session" button. This displays the Records List blade.
The timeline at the top of this screen covers the whole 24-hour period for the selected date, and represents the Doc Complete (ms) metric using a blue line. You can drag the time window to any time period of interest, and the lower timeline will update accordingly. Each Pageview for which a Record was captured is depicted in this lower timeline as a blue dot. Use the filter options on the left to further narrow down the Sessions/Pageviews displayed. You can select the desired Session or Pageview by clicking a blue dot in the timeline or by clicking the desired item in the list below it.
Waterfall
Once you have selected a Pageview to analyze, you will see its Waterfall chart displayed at the bottom of the screen. Use the Share button at the upper right to generate a link to a view-only version of this record that you can share with anyone.
Each row in the Waterfall chart contains details related to a single resource that was loaded as part of the Pageview. They are numbered in the order that each resource was requested. You can use the Search field to narrow down the items displayed by URL, Host, or Provider, and you can sort the data by any of the columns as well. The Zone dropdown lets you filter by the Zone that the Host belongs to.
On the far right of each row is a Gantt chart depicting the time period during which that resource was being loaded. Each step of the loading process is represented with a different color.
You can hover over the Gantt chart for any particular row to see a detailed breakdown of each step of the process.
