The ovf-monitor command monitors and displays overflow consumption on a port by port basis.
ovf-monitor {*|port{,port}{-port}...} {(options}
| * | Monitors all ports. This is the default. | |
| port{,port}{-port}...} | Specifies the port(s) or range of ports to monitor. | |
| options | a | Displays all target ports. By default, only the ports that are actively consuming overflow are displayed. |
| s | Enables scroll mode. Each new occurrence of activity is displayed as a new line in the output display. Note that older entries will scroll off the screen when the screen becomes full. | |
| tn | Specifies the time in n seconds between refreshes of the displayed ports. The default is 10 seconds. | |
Upon running ovf-monitor, a set of options display at the bottom of the results:
Press 8=up; 2=down;7=home;1=end;9-PgUp;3=PgDn;ESC=Exit;Rtn=Refresh
The options allow you to move up and down through the displayed results (not available when scrolling mode is enabled), refresh the displayed results or exit the program.
The example below illustrates using the ovf-monitor command to display all target pibs.

The example below illustrates setting the ovf-monitor command to use a scrolling display that refreshes every 2 seconds. In this case, only the activity on port 20 is being monitored.
