Sensorsoft Alert User Manual
by setting the ssTrapOnBooleanCriticalEnable to 1. By default, traps will be repeatedly sent at 5
minute intervals as long as the variable is in breach state. You can change this alerting interval by
specifying a new value (in minutes) in ssTrapOnBooleanCriticalInterval.
7. Setting up the return to normal traps:
Now that you have setup the traps to be sent in the breach conditions, you may also want a trap sent
when the variable’s reading returns back to normal. For instance, to have a trap sent when the
currently indexed variable returns to a normal state, you should set the
ssTrapOnReturnToNormalEnable object to 1.
Structure of SNMP Traps from Sensorsoft Alert
When the Alert appliance starts up, it will send a coldStart trap. When it shuts down, it will send a
linkDown trap. During operation of the Alert appliance, there are 1 to 8 enterprise specific traps that may
be sent out. The actual number of unique enterprise specific traps depends on the number of ports on your
Alert appliance. For instance, an 8 port appliance will have 8 enterprise specific traps, whereas a 4 port
appliance will only have 4. The specific trap number corresponds with the serial port which the monitored
device is connected to. For instance, if your NMS receives an enterprise specific trap from the Alert
appliance, and the trap number is 4, then the trap must have originated from an event on the device
connected to serial port 4. To find out what alert condition caused the trap, you must look at the trap’s
variable bindings.
