2 How events enter Veloopti

Events enter into your organisation though the following methods:

1. A policy running on a Veloopti agent detects a breach
   1. A logfile policy detects a match
   2. A SNMP trap is received that matches
2. A metric threshold is violated
3. It is injected by the Veloopti agent Application Programming Interface (API)

Once the event has been forwarded to Veloopti it is processed according to the following logic.

IF event matches outage rule THEN
     IF outage rule = suppress THEN
          Suppress the event
          EXIT
      ELSE IF outage rule = auto close THEN
          Create the event and close
          EXIT
      END IF
END IF
 
IF event matches one or more storm rules THEN
    Perform the storm rule(s)
END IF
 
IF event matches an existing event with a different severity THEN
    Change the existing events severity to match the new one
    Increment the existing events duplicate count by one
ELSE IF event matches an existing event with the same severity THEN
    Increment the existing events duplicate count by one
ELSE
    Create the event
    IF the event has a notification THEN
         Perform the notification
     END IF
 END IF
