BIG-IP Access (APM) Visibility

Overview: About the BIG-IP configuration for Access visibility

The F5 BIG-IQ Centralized Management Application Summary dashboard displays statistics for applications and users that are managed by the BIG-IP system. This includes the most requested applications, and how often individual users access the applications. For example, as an administrator, you can see the application summary report for the SharePoint application managed by the BIG-IQ system. You can use the report to track usage statistics, such as the request count for SharePoint and the most frequent users by request count. You can also adjust the time slider to see statistics for a certain time period.
To display these statistics, you must configure the BIG-IP system to classify the application traffic, create log messages, and send them to the BIG-IQ system. You can choose from two types of configurations:
Basic
A Basic configuration is your starting point to configure the BIG-IP system for application visibility. In some cases, you only need this option to generate the application logs and send them to the BIG-IQ system.
Advanced
In an Advanced configuration, after you configure a basic configuration and validate the reports, you might need to configure more BIG-IP resources such as classification presets and profiles. This situation typically occurs if there are no predefined classification profile in the application where you want to display statistics and reports.
Before you begin configuring application visibility, refer to
Access Reporting and Statistics
, in the
BIG-IQ: Monitoring and Reports
 guide.
Configure both BIG-IP and BIG-IP APM. Portal Access is not supported.
Sample Application Summary dashboard
Notice the length of time displayed by the line graph, dictated by the time slider above. Also notice the top ten applications, with SharePoint at number one. You can select an application and view the usage over time and the top users for that application.

View and configure the Application Summary dashboard

The BIG-IQ Centralized Management Application Summary dashboard displays information regarding the applications linked to the system.
  1. At the top of the screen, click
    Monitoring
    .
  2. On the left, select
    DASHBOARDS
    Access
    Application Summary
    .
The Application Summary screen opens, showing detailed information and charts for specific applications.

What is a basic configuration?

The basic BIG-IP system configuration for BIG-IQ application visibility is when a classification profile is already available to the administrator. This situation occurs when you want to track predefined access applications in BIG-IQ, such as SharePoint, OWA, PeopleSoft, or Lotus Notes. When you configure the virtual server for one or more of these applications, the BIG-IP system has already configured a classification profile. For most other applications, this basic configuration does not apply, and you must create the classification profile as well as other necessary resources.
In some cases, you might want to define your own signatures. If so, even in a basic configuration, you must upload the signatures in Traffic Intelligence.
For a basic configuration, configure the following resources in both the BIG-IQ and BIG-IP systems:
  • Enable remote logging in the Access area of BIG-IQ. Refer to the "BIG-IQ Centralized Management: Access" manual to learn how to configure remote logging.
  • Update classification signatures in BIG-IP Traffic Intelligence.
  • Configure a virtual server in BIG-IP Local Traffic.
  • Attach an existing classification profile to the virtual server.
You must use BIG-IP version 13.0 as well as BIG-IQ version 5.2 or later.
As part of the remote log configuration process, the system creates only the classification profile object name (classification _access). Because this classification profile is not attached to any virtual servers, you must add it to the virtual server used for applications that display reporting data. You should also enable the classification profile on the virtual server.

About traffic signatures for application visibility

Classification signatures
 define different types of traffic that the BIG-IP® system can recognize through Traffic Intelligence. The system recognizes a predefined set of signatures for common applications and application categories that are updated periodically. You can download signature updates from F5 Networks, and schedule the system to automatically update the signatures (pull the updated signatures automatically). You can also manually install the classification signatures and updates, for example, if the BIG-IP system does not have Internet access.
Signatures are updated once a month and have the following requirements:
  • Set up the DNS server on the BIG-IP system in order for the automatic updates to work.
  • The management network should be on the Internet.

Scheduling automatic signature updates

You can set up the BIG-IP system to automatically update the classification signatures. This ensures that the system always has the latest classification signature files.

Modify the virtual server for a basic configuration

Before you configure the virtual server in the BIG-IP system, you must enable remote logging in the BIG-IQ system.
For the BIG-IQ system to display statistics and reporting for an application such as SharePoint, OWA, or Lotus Notes, the application's virtual server must have a classification profile attached.
  1. In the Main tab, click
    Local Traffic
    Virtual Servers
    Virtual Server List
    .
    A list of existing virtual servers displays.
  2. Select the virtual server of the application that you wish to map to the BIG-IQ system.
    The virtual server editing (properties) screen opens.
  3. From the
    Configuration
     list, select
    Advanced
    .
  4. From the
    Classification Profile
     list, select
    classification_access
    .
    This classification profile was created by the BIG-IP system when you enabled remote logging in the BIG-IQ system.
  5. Click
    Update
    .
You have added a classification profile to the virtual server.

What is an advanced configuration?

If you want to display statistics and reports using the Access feature of BIG-IQ in an application that does not have a predefined classification profile, you must create the classification profile and attach it to the virtual server. This is considered an advanced configuration, and applies to most applications.
Because of this, you must configure the following resources in both BIG-IQ and BIG-IP systems:
  1. Enable remote logging in BIG-IQ Access. Refer to the
    BIG-IQ Centralized Management: Access
     manual to learn how to configure remote logging.
  2. Create a classification policy in BIG-IP system Traffic Intelligence screens.
  3. Create a new application from the Traffic Intelligence application list by customizing a category.
  4. Update the existing classification preset or create a new preset.
  5. Create a classification profile in the BIG-IP system's Local Traffic settings if you created a new classification preset. Otherwise, update the existing classification profile to include the existing preset.
  6. Configure a virtual server in the BIG-IP system's Local Traffic settings.
As part of the remote log configuration, only the classification profile object name (classification _access) is created. Because this classification profile is not attached to any virtual servers, you must add to the virtual server used for applications that display reports. You should also enable the classification profile on the virtual server.

Creating a custom local traffic policy

You can create a custom local traffic policy to manage traffic assigned to a virtual server.
  1. On the Main tab, click
