All,

New to Flink and more so with Flink CEP.

I want to write a sample program that does the following :

Lets suppose data cpu usage of a given server.

1. Want to Alert when CPU usage is above or below certain value
2. Want to Alert when CPU usage falls in a range
3. Want to Alert when the above condition matches n times in x interval (could be seconds, minutes, hours)
4. Want to Alert when the above condition happens continuously for x interval (could be seconds, minutes or hours) 

How would we achieve 3, 4 in the list above ? Any examples that I refer to ?

thank you,

Basanth
