This implementation describes how to view application statistics on the BIG-IP® system. It describes how you can examine the statistics in the Analytics charts
when Application Visibility and Reporting (AVR) is provisioned. Analytics charts display
statistical information about traffic on your system. The system updates the information every
The Overview screen shows all of the HTTP statistics in one place, including averages for
transactions per second (TPS), request and response throughput, server latency, page load time,
concurrent sessions, and new sessions. You can filter, drill down, and view selected information
by different metrics, such as by application, virtual server, URL, country, and so on.
The Analytics Custom screen provides a summary of the most frequent recent types of application
traffic, such as the most accessed virtual servers, URLs, pool members, and so on. You can design
the Analytics Custom screen so that it shows the specific types of data you are interested in.
You can schedule the reports to be sent to email addresses periodically. From any of the
displayed reports, you can also export them to a PDF file, or send the report to one or more
Note: The displayed Analytics
statistics are rounded up to two digits.
Examining application statistics
Before you can look at the
application statistics, you need to have created an HTTP Analytics profile so that the
system is capturing the application statistics internally on the BIG-IP® system. You must associate the Analytics profile with one or more
virtual servers (in the HTTP Analytics profile or in the virtual server). If you created
an iApp application service, you can use the provided template to associate the virtual

HTTP statistics for traffic on the BIG-IP system. The HTTP Overview screen provides
visibility into application behavior, user experience and client activity, transactions,
data center resource usage, and more.
On the Main tab, click
The Overview screen opens and displays current HTTP statistics averaged
over the last hour. On the screen, you can see time controls on the top, charts
on the left, and a list of dimensions on the right.
Use the time settings at the top of the screen to set a time range or refresh
the information on screen.
To immediately update the statistics on screen, adjust the time range or

applications, resource utilization, and more. You can focus on the specific data you
need using the filters and comparison chart option provided in the Dimensions pane.

About comparison charts
The AVR charts display aggregated statistics for your entire BIG-IP®
system. You can create customized charts based on specific, compatible data of interest, with
a comparison chart. You create comparison charts using dimension entities to highlight
specific data metrics, or to compare multiple entities in one chart.
Create a comparison chart using the
You can create new charts that
present statistic information about your BIG-IP® system for
selected entities from a dimension in the Dimensions pane. Once a new chart is created,
you can adjust the metric value that is presented. You can create multiple comparison
charts per screen.
On the Main tab, click
In the Dimensions pane, expand a dimension widget to view its entity
Select one or more dimension entities for the comparison chart by clicking the
entity title. You can also select entities in other dimensions that have
entities automatically filters information in the Charts pane and compatible
data in other dimensions. You can remove these filters once the comparison

About the reporting interval for charts and reports
The system updates the statistics for charts and reports at five minute intervals: at five
minutes after the hour, ten minutes after the hour, and so on. Each five-minute mark includes
data from the previous five minutes; so 12:45 includes data starting from 12:40:01 to
Charts and data that you export from charts reflect the publishing interval of five minutes.
For example, if you request data for the time period 12:40-13:40, the data in the chart or in the
file that you export is for that time period. But if there is a request for data from
12:42-13:42, the data in the chart is from 12:45-13:45. By default, the BIG-IP® system displays one hour of data.
Saving or emailing report files
To send reports by email, the default analytics profile must
specify an SMTP configuration ( ).
You can export or email any of the
Analytics charts including those which display statistics for HTTP, TCP, memory, disk,
virtual servers, and other charts available on your system.
On the main tab, click
and select the type of chart to display.
Adjust the chart so that it shows the information you want, adjusting the
content as needed.
On the upper right of the charts screen, click

Customizing your statistics view
Before you can view HTTP
application statistics, you need to have created an Analytics profile so that the system
is capturing the application statistics internally on the BIG-IP®
system. You must associate the Analytics profile with one or more virtual servers (in
the Analytics profile or in the virtual server). If you created an iApp application
service, you can use the provided template to associate the virtual server.
You can customize how you view
statistics by displaying the information you want, organized as you want to see it into
data-specific widgets. A set of default widgets is provided showing HTTP
statistics for the top URLs, pool members, virtual servers, client subnets, and
countries. You can create additional widgets or reorganize what's there.
On the Main tab, click
The Custom Page opens showing current HTTP statistics. By default, there
are five widgets organized in two columns.
To view statistics for a particular device group, from the
Device Group list, select the one you want.
To adjust the time range for all widgets, from Override time
range to, select a new time frame for which to view
If you select (per widget), you can specify
different time ranges for each widget.
For each widget you want to change, click the gear icon and select
The Modify Widget Properties popup opens where you can change what the
widget shows and the format used.
To change the order of the widgets, drag them up or down within the
To delete a widget if you do not need that information, click the gear icon and
To focus in on the specific details you want more information about in any
widget, click an item in the chart.
The system refreshes the charts and displays information about the
item. Click Back to return to the Custom Page.
To create a new widget in either column, click Add
Widget at the bottom of the column.
Fill in the Add New Widget popup screen to define the widget.
From the Available Measurements, select the
measurement to use.
If there is a choice, select the data visualization.
The new widget displays in the column.

Note: The timestamp
on the report reflects a publishing interval of five minutes; therefore, a
time period request of 12:40-13:40 actually displays data between
12:35-13:35. By default, the BIG-IP system displays one hour of data.
You can continue to adjust the
