•Device: The name of the device
•Variable: The MIB variable being monitored
• Sample Type: Absolute or Delta
• Sample Interval: The time between samples, in seconds.
• Rising Threshold: A threshold value that will trigger an event when the value of the
variable increments past this value.
•FallingThreshold:A threshold value that will trigger an event when the value of the
variable decreases past this value.
•Startup:The condition that will cause the initial event (Rising, Falling, or
RisingOrFalling).
•Index, the device index as obtained by the EPICenter server from the device.
For a detailed definition of these parameters, see “RMON Rule Configuration” on
