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:
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 file, or send the reports to one or more email addresses.
|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 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.
