Subject Flink CEP questions
Date Thu, 17 Aug 2017 13:32:02 GMT
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
