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.

Advanced performance monitor settings for general options

For the General Options list, this table describes the Advanced settings and strings for Performance Monitor Options.

Advanced control Default Description
Performance Monitor Disabled Specifies whether performance monitoring for this application is enabled. Enabling performance monitoring on many applications might affect the overall performance of the BIG-IP.
Data Retention Period 30 Specifies the period, in days, that the performance data must be preserved.

Overview: 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.

About Byte Savings reports

Byte Savings reports provide statistics for cached objects that are either optimized or simply cached, as a means to minimize the traffic sent to a client. Byte Savings reports include four types of reports: Caching Bytes Saved, Compression Bytes Saved, Image Optimization Bytes Saved, and Minification Bytes Saved.

Caching Bytes Saved reports

Cache Bytes Saved reports provide statistics about the number of kilobytes served from cache, describing the reduction in bandwidth between the origin web server and the BIG-IP system.

Compression Bytes Saved reports

Compression Bytes Saved reports provide statistics about the reduction in kilobytes sent to the client, when BIG-IP system performs compression instead of the origin web server.

Image Optimization Bytes Saved reports

Image Optimization Bytes Saved reports provide statistics about optimized images in kilobytes, which reduces the sizes of images sent to the client.

Minification Bytes Saved reports

Minification Bytes Saved reports provide statistics about minified JavaScript and cascading style sheet (CSS) objects in kilobytes, reducing the sizes of objects sent to the client.

About Caching Requests Saved reports

Caching Requests Saved reports provide statistics about the number of requests that are served from cache, which reduces the load for the origin web server.

About IBR Savings reports

IBR Savings reports provide statistics about Intelligent Browser Referencing (IBR) links that have been sent or received from a client. IBR Saving reports include two types of reports: Client IBR'd Links and Client IBR'd Links Received reports.

Client IBR'd Links reports

Client IBR'd Links reports provide statistics about the number of IBR links that have been sent to a client. You will want to use the statistics for this setting in combination with the Client IBR'd Links Received statistics, to determine the number of links that eliminated unnecessary conditional GET requests by increasing the content expire time.

Client IBR'd Links Received

Client IBR'd Links Received reports provide statistics about the number of IBR links that have been received from a client. You will want to use the statistics for this setting in combination with the Client IBR'd Links statistics, to determine the number of links that eliminated unnecessary conditional GET requests by increasing the content expire time.

About Inlined Links reports

Inlined Links reports provide statistics about the number of links that become inlined when sending a response to a client, reducing the number of GET requests from the client.

About ICC Savings reports

ICC Savings reports provide statistics about links that Intelligent Client Cache (ICC) functionality provides for a client. ICC Savings reports include two types of reports: ICC Inlined Links and ICC Referenced Links reports.

ICC Inlined Links

ICC Inlined Links reports provide statistics about the number of links that become inlined for a client by ICC functionality, reducing the number of GET requests from the client.

ICC Referenced Links

ICC Referenced Links reports provide statistics about the number of links referencing content that might exist in the client's local storage, added by ICC functionality.
