16 Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide • Sample Type - Defines the sampling method for the selected variable and comparing the value against the thresholds. The possible field values are: - Delta - Subtracts the last sampled value from the current value. The difference in the values is compared to the threshold. - Absolute - Compares the values directly with the thresholds at the end of the sampling interval. • Rising Threshold - Displays the rising counter value that triggers the rising threshold alarm. The rising threshold is presented on top of the graph bars. Each monitored variable is designated a color. • Rising Event - Selects an event which is defined in the Events table that triggers the rising threshold alarm. The Events Table is displayed in the RMON Events page. • Falling Threshold - Displays the falling counter value that triggers the falling threshold alarm. The falling threshold is graphically presented on top of the graph bars. Each monitored variable is designated a color. • Falling Event - Selects an event which is defined in the Events table that triggers the falling threshold alarm. The Events Table is displayed in the RMON Events page. • Startup Alarm - Displays the trigger that activates the alarm generation. Rising is defined by crossing the threshold from a low-value threshold to a higher-value threshold. • Interval - Defines the alarm interval time in seconds. • Owner - Displays the device or user that defined the alarm. 3.
