### Main Monitor Window

Use this topic to learn more about the DPA - Remote main monitor window options, controls and fields.

#### Options

The Options menu item lets you control the polling interval, SNMP timeout, scale of graphical presentations, and the font size of displayed information. Note that with the exception of font size, the options affect only the displays in the current monitor window. Font size adjustments affect all displays in all windows that have been opened by the DPA - Remote Control Panel.

Option | Description
Poll Interval | The time, in seconds, between updates of the displayed information. The default is 1 second. The same poll interval is used for all DPA - Remote monitoring functions and displays for this device.
SNMP Timeout | The time, in seconds, to wait for an SNMP response, before assuming that the device is not present, or not ready. The default is 3 seconds. This setting applies to all display frames for the current device monitor window, but not to monitor windows opened for other devices.
Graph Scale | Adjusts the scale of graphical presentations so that the graphs show 0%-10%, 0%-30%, 0%-50% or 0%-100%. Each graph type (network/port/processor & memory utilization) may be set individually. These settings apply to display frames for the current device monitor window, but not to monitor windows opened for other devices.
Font Size | Adjusts the font size of displayed information. The setting of this option affects all frames in all monitor windows that have been opened from the DPA - Remote Control Panel.

To close the frame, choose the port button once more. green - Indicates that activity is detected on the port. white - Indicates the port is up. gray - indicates the port is down. yellow - Indicates the port is in maintenance mode. See Port Monitor Fields and Graphs for more information.
