6014.0. "Notification ordering problem with events via rules" by BACHUS::FOLENS () Thu Jun 09 1994 06:36
I'm currently using DECmcc v1.3.
I have created 3 occurs alarm rules:
Domain QUAKER:.backbone Rule router_circuit_down
AT 9-JUN-1994 12:27:25 Characteristics
Examination of attributes shows:
Alarm Fired Procedure = DISK$DATA_1:[FOLENS]MCC_ROUTER_CIRCUIT
_STATE.COM;4
Expression = (OCCURS (Node4 * circ * circuit down))
Severity = Critical
Probable Cause = Unknown
Domain QUAKER:.backbone Rule router_circuit_down_fault
AT 9-JUN-1994 12:27:35 Characteristics
Examination of attributes shows:
Alarm Fired Procedure = DISK$DATA_1:[FOLENS]MCC_ROUTER_CIRCUIT
_STATE.COM;4
Expression = (OCCURS (Node4 * circ * circuit down
circuit fault))
Severity = Critical
Probable Cause = Unknown
Examination of attributes shows:
Alarm Fired Procedure = DISK$DATA_1:[FOLENS]MCC_ROUTER_CIRCUIT
_STATE.COM;4
Expression = (OCCURS (Node4 * circ * circuit up))
Severity = Warning
Probable Cause = Unknown
The purpoose is to detect failure of WAN links and to get a procedure executed
to log the problem to DCM.
Now it happens that a link goes down for a very short period of time.
Thus I receive first an 'circuit down' event and right after a 'circuit up'
event.
Now notification seems to have a problem to report these event in the right
order although that the time reported is right:
The last event detected: Node4 QUAKER:.routers.qbr900 Circuit SYN-0 Circuit Up
9-JUN-1994 05:25:48.81
The last event detected: Node4 QUAKER:.routers.qbr900 Circuit SYN-0 Circuit Down
Circuit Fault 9-JUN-1994 05:25:48.39
If I don't use rules but notify requests the order is correct. What can I do
about it?
