system provides a dashboard that you can use to monitor overall system performance and performance of specific modules. The dashboard displays system statistics graphically, showing gauges and graphs, and you can view the same statistics in a table view. Information is updated every three seconds.
This chapter describes how to display the dashboard screens. The dashboard
includes online help for information about how to interpret the statistics on each of the panels that appear on the screens. Click the ?
in the upper right corner of any panel to display the online help.
shows a typical Performance overview screen in the dashboard.
The CPU panel of the Performance Overview screen displays CPU statistics
in a gauge, showing the busiest CPU; a chart, showing the busiest CPU, average CPU usage, and the least busiest CPU; and a table view that shows details for each CPU including fan speed, temperature, and usage.
shows the graphic view of the CPU panel. The busiest CPU is using 89.1% of its CPU capacity on all system management and application tasks.
The Memory panel of the Performance Overview screen displays the
amount of total system memory is currently in use. A chart breaks down memory usage into how much the Traffic Management Microkernel (TMM) is using for traffic management, and how much is being used for all other processes, such as those for system configuration and monitoring.
shows the graphic view of the Memory panel. In this example, the Memory Usage gauge shows that 77.5% of the total system memory is currently in use.
The Breakdown chart in the figure shows that of the 4.1 GB of memory
allocated on this BIG-IP system, processes other than TMM are using most of the memory. The Usage % chart shows that memory usage over the last five minutes has been steady at about 77%.
The Statistics panel of the Performance Overview screen displays the total
open TCP connections on the system, and separately lists new connections, SSL connections, and all active connections for the time specified.
, shows the graphic view of the Statistics panel with the Open tab selected. It shows that during the last 5 minutes the system has had up to 32,000 open connections, and now it has 16,702 connections.
The Throughput panel of the Performance Overview screen summarizes the
amount of traffic in bits per second that the system has handled during the time specified in the timeframe menu. It also separately shows SSL throughput, compression throughput, and all throughput.
shows the graphic view of the Throughout panel with the Total tab selected. The total throughput on the system for the last 5 minutes ranges between about 510 Mbps and 900 Mbps.
If you have licensed and provisioned other modules on the BIG-IP system
that support the dashboard, you can view statistics specific to the module (for example, the WAN Optimization Module).
