Overview: Examining and exporting application statistics

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, including the following details:

  • Overview
  • Transactions
  • Latency
  • Throughput
  • Sessions

The system updates the Analytics statistics every five minutes (you can refresh the charts periodically to see the updates). The Analytics Overview provides a summary of the most frequent recent types of application traffic, such as the top virtual servers, top URLS, top pool members, and so on. You can customize the Analytics Overview so that it shows the specific type of data you are interested in. You can also export the reports to a PDF or CSV file, or send the reports to one or more email addresses.

Note: The displayed Analytics statistics are rounded up to two digits, and might be slightly inaccurate.

Examining application statistics

Before you can look at the 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.
Note:

Newer browsers (Internet Explorer 9 or later, Firefox 3.6 or later, or Chrome 14 or later) support viewing Analytics charts with no additional plug-in. If using older browsers (Internet Explorer 8 or earlier, Firefox 3.5 or earlier, or Chrome 13 or earlier), Adobe Flash Player (version 8 or later) must be installed on the computer where you plan to view Analytics charts.

You can review charts that show statistical information about traffic to your web applications. The charts provide visibility into application behavior, user experience, transactions, and data center resource usage.
  1. On the Main tab, click Statistics > Analytics > HTTP. The Overview screen opens.
  2. From the Override time range to list, select a new time frame to apply to all of the widgets in the overview.
    Tip: Within each widget you can override the default time range, as needed.
  3. For each widget, select the data format and the time range to display, as needed.
  4. From the menu bar, select the type of statistics you want to view.
    Select this option To see these application statistics
    Overview Top statistical information about traffic on your system or managed systems, such as the top virtual servers, top URLs accessed, and top applications. You can customize the information that is displayed.
    Transactions The HTTP transaction rate (transactions per second) passing through the web applications, and the number of transactions to and from the web applications.
    Latency > Server Latency The number of milliseconds it takes from the time a request arrives at the virtual server until a response arrives at the virtual server.
    Latency > Page Load Time The number of milliseconds it takes for a web page to fully load on a client browser, from the time the user clicks a link or enters a web address until the web page displays in its entirety.
    Throughput > Request Throughput HTTP request throughput in bits per second.
    Throughput > Response Throughput HTTP response throughput in bits per second.
    Sessions > New Sessions The number of transactions that open new sessions, in sessions per second.
    Sessions > Concurrent Sessions The total number of open and active sessions at a given time, until they time out.
    The charts display information based on the settings you enabled in the Analytics profile.
  5. From the View By list, select the specific network object type for which you want to display statistics. You can also click Expand Advanced Filters to filter the information that displays.
  6. To focus in on the specific details you want more information about, click the chart or the details. The system refreshes the charts and displays information about the item.
  7. On the screen, the system displays the path you followed to reach the current display, including the items you clicked. For example, to review throughput details for a particular virtual server, follow these steps:
    1. From the Throughput menu, choose Request Throughput.
    2. From the View By list, select Virtual Servers. The charts show throughput statistics for all virtual servers on this BIG-IP system. You can point on the charts to display specific numbers.
    3. Click the virtual server you want more information about. You can either click a part of the pie chart or click the name of the virtual server in the Details table. The charts show throughput statistics for that virtual server, and shows the path you used to display the information.
    4. To view information about other applications or retrace your path, click a link (in blue) in the path displayed by the charts.
    As you drill down into the statistics, you can locate more details and view information about a specific item on the charts.
You can continue to review the collected metrics on the system viewing transactions, latency, throughput, and sessions. As a result, you become more familiar with the system, applications, resource utilization, and more, and you can view the statistics in clear graphical charts, and troubleshoot the system as needed.

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.

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 the time period 12:35-13:35. By default, the BIG-IP system displays one hour of data.

Exporting or emailing application statistics

To send reports by email, the default analytics profile must specify an SMTP configuration (Local Traffic > Profiles > Analytics).
You can export or email charts that show application statistics.
  1. On the Main tab, click Statistics > Analytics > HTTP. The Overview screen opens.
  2. Display the charts that show the information you want, clicking any of the menu bar options and adjusting the content as needed.
  3. On the upper right of the charts screen, click Export.
    Tip: You can also export any single report widget from the Overview screen. Click the widget configuration icon for the report and select Export.
    The Choose Export Options popup screen opens.
  4. Choose the appropriate options.
    Option Action
    Export the data in option format Specify the export format:
    • Select PDF to save the information in a graphical format to a PDF file.
    • Select CSV (Time Series) to export the information to a text file including specific information for time increments.
    • Select CSV (Details Table) to export the information to a text file providing summary details.
    If exporting the entire Overview screen, the information is saved only in PDF format (no export format options are available). When exporting widgets, the format options are PDF or CSV (only one CSV format is provided).
    Save the report file on your computer Select this option to save or open the file containing the report.
    Send the report file as an attachment to the following E-mail address(es) Type one or more email addresses (separated by comma or semicolon) to which to send the report.
  5. Click Export. The system saves the report to a file, or emails the file to the specified recipients. If SMTP is not configured (when sending reports by email), you receive a message that SMTP must be set up before you can send the reports.

Creating an SMTP server configuration

You specify the SMTP server configuration so that you can send emails through an SMTP server.
  1. On the Main tab, click System > Configuration > Device > SMTP.
  2. Click the Create button. The New SMTP Configuration screen opens.
  3. In the Name field, type a name for the SMTP server that you are creating.
  4. In the SMTP Server Host Name field, type the fully qualified domain name for the SMTP server host.
  5. In the SMTP Server Port Number field, type a port number. For no encryption or TLS encryption, the default is 25. For SSL encryption, the default is 465.
  6. In the Local Host Name field, type the host name used in the SMTP headers in the form of a fully qualified domain name. This host name is not the same as the BIG-IP system's host name.
  7. In the From Address field, type the email address that you want displayed as the reply-to address for the email.
  8. From the Encrypted Connection list, select the encryption level required for the SMTP server.
  9. To require that the SMTP server validates users before allowing them to send email, select the Use Authentication check box, and type the user name and password required to validate the user.
  10. Click the Finish button.
You can now configure the system to use this SMTP server to send emails. For the SMTP mailer to work, you must make sure the SMTP server is on the DNS lookup server list, and configure the DNS server on the BIG-IP system.
