This release note documents the version 11.0.0 release of the Analytics Module.
Note: F5 offers general availability releases and general sustaining releases. For detailed information on our policies, refer to SOL8986, F5 software lifecycle policy.

You can work with the BIG-IP® Configuration utility using the following browsers:
Note that we recommend that you leave the browser cache options at the default settings.
Important: Popup blockers and other browser add-ons or plug-ins might affect the usability of the browser-based Configuration utility. If you experience issues with navigation, we recommend that you disable these types of browser plug-ins and add-ons.
To view a list of supported platforms, see SOL10288: BIG-IP software and platform support matrix.
If you are unsure which platform you have, look at the sticker on the back of the chassis to find the platform number.
The following instructions explain how to install the Analytics Module version 11.0.0.
This section lists only the very basic steps for installing the software. The BIG-IP® Systems: Getting Started Guide contains details and step-by-step instructions for completing an installation. F5 recommends that you consult the getting started guide for all installation operations.
The steps in this section assume that:
Installation consists of the following steps.
After the installation finishes, you must complete the following steps before the system can pass traffic.
Each of these steps is covered in detail in the BIG-IP® Systems: Getting Started Guide, and we recommend that you reference the guide to ensure successful completion of the installation process.
The upgrade process installs the software on the inactive installation location that you specify. This process usually takes between three minutes and seven minutes. During the upgrade process, you see messages posted on the screen. For example, you might see a prompt asking whether to upgrade the End User Diagnostics (EUD), depending on the version you have installed. To upgrade the EUD, type yes, otherwise, type no.
You can check the status of an active installation operation by running the command tmsh show sys software.
If installation fails, you can view the log file. The system stores the installation log file as /var/log/liveinstall.log.
After upgrading or installing a new version, before you can use the Analytics Module, you must set the Analytics Module resource provisioning level to Nominal. You can do this from the command line, or using the Configuration utility.
To set the Analytics Module resource provisioning level to Nominal from the command line
Open the command line interface utility, and run the following commands:
tmsh modify sys provision avr level nominal
tmsh save sys config
To set the Analytics Module resource provisioning level to Nominal using the Configuration utility
Important: Wait 5 minutes after you set the resource provisioning level before making any configuration changes to the Analytics Module. The system overrides all configuration changes made before this process is completed. The system informs you when the process is not completed by displaying, in the Configuration utility, the following message: AVR is not ready. The system informs you when the process completed by indicating in the log (/var/log/avr) the following message: AVR started successfully.
This release introduces BIG-IP Analytics, also known as Application Visibility and Reporting (AVR). Analytics is a module on the BIG-IP® system that lets you analyze performance of web applications. It provides detailed metrics such as transactions per second, server latency, page load time, request and response throughput, and sessions. You can view metrics for applications, virtual servers, pool members, URLs, specific countries, and additional detailed statistics about an application. You can use the Configuration utility filters to configure which traffic the system captures, publishes and analyzes.
Transaction counters for response codes, user agents, HTTP methods, countries, and IP addresses provide statistical analysis of the traffic that is going through the system. You can capture traffic for examination and have the system send alerts so you can troubleshoot problems and immediately react to sudden changes.
Use the remote logging capabilities to consolidate statistics gathered from multiple BIG-IP appliances onto syslog servers or Security Information and Event Management (SIEM) devices, such as Splunk.
You must provision AVR. AVR is provisioned separately from the Local Traffic Manager™, but requires the Local Traffic Manager be provisioned.
Once you have provisioned AVR, you can perform the following:
Important: You must have Adobe Flash Player installed on the computer where you plan to view Analytics statistics.
The following items are known issues in the current release.
Different methods of calculating statistics (ID 344054)
The system calculates statistics differently in the graphs and in the table. In the graphs, the system displays a snapshot of statistics recorded at a specific point in time, every five minutes. In the table, the system displays a cumulative number of statistics recorded.
Report delay (ID 344763)
It may take up to a few minutes for the system to display in the graphs changes made to the Analytics configuration.
Compressed responses (ID 346255)
Analytics does not collect page load time statistics for gzipped (compressed) responses.
Collecting response code statistics (ID 346258)
Response code statistics are collected on URLs, not on Virtual Server IP addresses or Pools. Therefore, to collect response code statistics, you must enable the collection of URL statistics.
Virtual server traffic when AVR not provisioned (ID 355362, ID 349658)
If AVR is not provisioned, or if you un-provision AVR, and you assign an Analytics profile to a virtual server, traffic will not pass through the virtual server. In addition, in the Configuration utility, the Analytics Profile setting is visible in the virtual server's advanced properties screen even when AVR is not provisioned on the machine.
URL Decoding (ID 350381)
Analytics does not perform URL decoding, and therefore logs normalized and not normalized URLs as different URLs.
Global Traffic Manager pools and Analytics Statistics (ID 351257)
Health monitor requests for Global Traffic Manager™ (GTM) pools or servers are shown in Analytics statistics.
