Overview: Monitoring the performance of a BIG-IP acceleration application

The BIG-IP's performance reports provide information about page requests, the frequency of those requests, and how well the BIG-IP system serviced those requests from cache. Additionally, performance reports provide information about the acceleration application, policy, policy node, HTTP response status, S-code, size range of the response, response object type, and ID of the BIG-IP system or browser making the request.

The BIG-IP system provides three types of performance reports.

  • Traffic Reports. These reports display the number of requests (hits) received, and responses served, by the BIG-IP system.
  • Byte Reports. These reports display the bytes of content that the BIG-IP system has sent in response to requests.
  • Response Reports. These reports display the average amount of time it takes the BIG-IP system to respond to a request from the client.

You can use these performance reports to evaluate your acceleration policies, adjusting them as required to maximize client access to your applications. The individual performance reports display content according to the persistent parameters that you select for the filter. You can also save performance reports to a specified file type so that you can import them into specific applications.

Note: Enabling performance monitoring for a BIG-IP acceleration application can degrade overall performance and should only be used temporarily.

  4. From the Performance Monitor list, select Enable.
  5. In the Data Retention Period field, type the number of days to retain data.
  6. Click Save.
Performance monitoring is enabled for the application.

Disabling performance monitoring for a BIG-IP application

You can disable performance monitoring for a BIG-IP application, as necessary.
  1. On the Main tab, click Acceleration > Web Application > Applications .
    The Applications List screen opens.
  2. Click the name of an application.
  3. From the General Options list, select Advanced.
  4. From the Performance Monitor list, select Disable.

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.

The new pool appears in the Pools list.

Overview: Configuring ROI reports

You can evaluate the benefits and performance improvements of acceleration functionality for an application by examining ROI Statistics. Acceleration ROI Statistics provide data on compression, caching, minification, inlining, image optimization, and Intelligent Browser Referencing (IBR), which you can assess to determine the current acceleration performance, and, based on those results, refine the acceleration performance.
