Performance
This dashboard panel displays performance information for your software, appliance size and CPU. For the software and sizing performance calculations you can modify the thresholds by clicking in the colored percentage bar.
Thresholds used to calculate % Used or % Capacity information can be modified from the Performance panel. Hover over the colored bars to display threshold settings. Click on the colored bar to modify threshold settings. Thresholds can also be modified from the Events Management window. See Event thresholds. Threshold changes are global and affect all users.
Color |
Definition |
---|---|
Green |
Percentage used is below the warning threshold. |
Yellow |
Percentage used is above the warning threshold, but below the critical threshold. |
Red |
Percentage used is above the critical threshold. |
Hardware
The system uses as much RAM as is available. The underlying operating system is optimized to use RAM as efficiently as possible. Swap space is configurable, but only by Customer Support. The sum total of space available in RAM and available in swap represents the total amount of virtual memory available on the system.
The disk space representing each directory on the file system is displayed. Thresholds used to calculate Memory+Swap and Disk Used percentages can be modified from the Performance panel by clicking on the colored bar.
Software
Memory is allocated to each of the internal loader processes in the FortiNAC appliance, such as the "master loader". The amount of memory allocated to these processes varies from platform to platform, and is configurable, but only by Customer Support.
Thresholds used to calculate Threads and Used Memory percentages can be modified from the Performance panel by clicking on one of the colored bars.

System Start Time |
Time the software was started. |
System Up Time |
Amount of time the software has been running. |
Process |
Processes that are currently running. If a process is not running it is not displayed. Possible processes include: Principal Nessus |
Threads |
Number of threads being used by a particular process. The thread count for master loader is: Minimum: warning: 500 critical: 575. These numbers may automatically increase depending on the capabilities of the hardware or virtual machine. |
Total Memory |
Total Memory allocated for each process. |
Free Memory |
Portion of Total Memory not being used for each process. |
Used Memory |
Percentage of total memory being used for each process. The amount of memory allocated. |
CPU usage
The graph contained in this tab displays the percentage of CPU Usage. The data contained within the graph is not stored and is based on data points retrieved at each refresh interval. In an environment with a pair of servers, there are separate lines for the FortiNAC Control Server and FortiNAC Application Server.
