When you select a property and click on Performance, the navigation pane expands to show the various available pages of web performance analytics for the traffic served from this property.
The available analytics screens are Performance Overview and Mobile App (if the Mobile App Acceleration service is enabled on your account).
At the top of the screen just above the page title is a panel of filters that you can apply to the data that is displayed:
The panel can be collapsed by clicking Hide Filters. With the panel open, you can change to another domain and filter by time; additionally, specific screens have one or more page-specific filters that will appear; for example, the Performance Overview screen has filters for Browser, Device type, and Country.
Click the Apply Changes button to engage the selected filters.
For filtering by domain, All Domains is selected by default. You can uncheck one or more of the entries in the list to narrow it to a subset, or click All Domains to unselect everything and then check the ones you want. You can quickly find a specific domain by starting to type the domain name, and the list's scrollbar will adjust accordingly.
For filtering by time, you can choose Today (the default), 1 week, By month, or Custom Range to specify a custom time period.
For filtering by browser, All browsers is selected by default. You can uncheck one or more of the entries in the list to narrow it to a subset, or click All Browsers to unselect everything and then check the ones you want.
Similarly, for filtering by device type, All device types is selected by default. You can uncheck one or more of the entries in the list to narrow it to a subset, or click All Device Types to unselect everything and then check the ones you want.
For filtering by country, All Countries is selected by default. You can uncheck one or more of the entries in the list to narrow it to a subset, or click All Countries to unselect everything and then check the ones you want. You can quickly find a specific country by starting to type the country name, and the list's scrollbar will adjust accordingly.
The Performance Overview screen allows you to view a summary of the performance benefits from using our HTML Streaming feature for dynamic web pages. This screen provides a view into the benefit HTML Streaming provides over a number of key web performance metrics, including Time to First Byte (when the first bit of HTML is received to the browser), Time to DomContentLoaded event (when the browser has loaded up the HTML document), and Time to OnLoad event (when the page is mostly displayed and interactive for the user).
To access the screen, select Performance Overview from the Performance section of the navigation panel. This opens the Web Performance Analytics screen in the main pane:
The graph shows the Base time (from traffic where HTML Streaming is not enabled) compared to the Accelerated time (from traffic where HTML Streaming is in effect). This gives you a quick visual indication of how the feature is performing on your site. Hovering the cursor over any point on the graph shows the values at that moment.
The default view displays Time to First Byte over the last 24 hours. You can also view the time to the DomContentLoaded event or the OnLoad event by selecting from the Metric pulldown.
|Note||The Mobile App page only appears in the portal if you have purchased the Mobile App Acceleration service. This service boosts performance for native and hybrid applications on iOS and Android mobile devices. Please contact firstname.lastname@example.org to learn more.|
The first part of the Mobile App page is the Timeline graph, which plots speed in Mbps over time. The time axis units depend on the current time filter setting. For example, with the time set to 1 day, the time axis shows units of hours:
If you hover the mouse pointer over a point on the plot, the bandwidth at that point is displayed in a box alongside the mouse pointer, with five-minute granularity.
You can also drag either the left or right side of the zoom control just beneath the timeline to focus on a narrower range of times.
Two traces are displayed: DPR – traffic over the Mobile App Dynamic Packet Recovery protocol – and TCP – traffic delivered via standard TCP.
Below and to the left, the Total Accelerated Mobile Traffic and Total Mobile Uplift are displayed:
Uplift is the aggregated speed improvement provided by DPR for the currently-selected time period and network type. The network type can be Wi-Fi, 4G-LTE, 3G-HSPA, 3G-EVDO, or All.
To the right is a donut chart of Aggregate Sessions By Device OS. You can hover over one of the segments of the donut to display numeric data for that particular OS:
In the next row on the left is the Aggregate Sessions By Country display. This has two ways of visualizing locations that requests have come from – a global map (the default view), or a donut chart. These are selected by clicking the icons at the top right of the box.
For the map view, you can hover the mouse pointer over a country on the map to display numeric data for that particular country:
For the donut chart view, you can similarly hover over one of the segments of the donut to display numeric data for that particular country:
To the right is the Aggregate Sessions By Network donut chart. You can hover over one of the segments of the donut to display numeric data for that particular network:
