The fields you enter values into are combined into a search string with a logical AND. For 
example, if you enter values for Source IP and Destination IP, the search string will look for 
connections matching:

Source IP AND Destination IP

Check the Group box next to any two or more criteria to combine them with a logical OR. For 
example, if you enter values for Source IP, Destination IP, and Protocol, and check Group 
next to Source IP and Destination IP, the search string will look for connections matching:

(Source IP OR Destination IP) AND Protocol

Click Apply Filter to apply the filter immediately to the Active Connections Monitor table. 
Click Reset Filters to clear the filter and display the unfiltered results again. 

You can export the list of active connections to a file. Click Export Results, and select if you 
want the results exported to a plain text file, or a Comma Separated Value (CSV) file for 
importing to a spreadsheet, reporting tool, or database. If you are prompted to Open or Save 
the file, select Save. Then enter a filename and path and click OK. 

The CPU Monitor diagnostic tool shows real-time CPU utilization in second, minute, hour, and 
day intervals (historical data does not persist across reboots). 

High CPU utilization is normal during Web-management page rendering, and while saving 
preferences to flash. Utilization by these tasks is an indication that available resources are 
being efficiently used rather than sitting idle. Traffic handling and other critical, performance-
oriented and system tasks are always prioritized by the scheduler, and never experience 
starvation.
