Example: Interface status actively checked every 4 hours. 0:00 - Active Check OK 1:20 - Passive check causes CRTIICAL state. 1:25 - Passive check causes OK state. 4:00 - Active Check OK 8:00 - Active Check OK 9:29 - Passive check causes CRITICAL state. 10:00 - Passive check casues OK state. State change in this case is 5/7 (57%). If based on a time period of minutes you get 5/600 (.008%). Just an idea to allow for passive monitoring to be better handled with flap detection. ---- Larry Low 4150 N Drinkwater Blvd., 5th Floor Scottsdale, AZ 85251 E-mail: <a href="mailto:llow@telesphere.com">llow@telesphere.com</a>' Telesphere Networks, Inc ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
