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. The system updates the information every five minutes.
The Overview screen shows all of the HTTP statistics in one place, including averages for transactions per second (TPS), request and response throughput, server latency, page load time, concurrent sessions, and new sessions. You can filter, drill down, and view selected information by different metrics, such as by application, virtual server, URL, country, and so on.
The Analytics Custom screen provides a summary of the most frequent recent types of application traffic, such as the most accessed virtual servers, URLs, pool members, and so on. You can design the Analytics Custom screen so that it shows the specific types of data you are interested in.
You can schedule the reports to be sent to email addresses periodically. From any of the displayed reports, you can also export them to a PDF file, or send the report to one or more email addresses.
|Time Focus||Select the time range of the displayed data.
Note: Additional time options become available as your system gathers more data.
|Currently Selected Time Range||Displays the current time range of the displayed data.|
|Auto-Refresh Interval Selector||Select how frequently the data on this screen is refreshed.|
|Real Time||Activates the real time option to reflect the most current traffic status in the Charts area|
|Manual Refresh||Click Refresh to trigger an immediate refresh of the displayed data.|
|Manual Time Adjustment Handles||Set the data to a specific window of time within the
currently selected time range. Use the handles at either end
of the time line to define the specific time you want to
examine. Use the handle above the time line to display data
that is outside the selected time range.
Note: Adjusting the time range to display previous data stops the auto-refresh so you can focus on a specific data point.
You can save the statistics in a file, and send the file to select users by email. You can also set up schedules to send specific reports to specific users (go to the Scheduled Reports screen,).
The AVR charts display aggregated statistics for your entire BIG-IP system. You can create customized charts based on specific, compatible data of interest, with a comparison chart. You create comparison charts using dimension entities to highlight specific data metrics, or to compare multiple entities in one chart.
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. Each five-minute mark includes data from the previous five minutes; so 12:45 includes data starting from 12:40:01 to 12:45:00.
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 that time period. But if there is a request for data from 12:42-13:42, the data in the chart is from 12:45-13:45. By default, the BIG-IP® system displays one hour of data.
