Subject Re: [GSOC - 2015] Introducing “curve fitting” for statistics prediction algorithm of Autoscaler
Date Fri, 27 Mar 2015 08:25:25 GMT
Hi Lahiru,

I made the proposal public to everyone. But I think the proposal is still
not accessible. I do not figure what is the reason. :(

Hi all,

With the few days of research on the project

"Introducing “curve fitting” for statistics prediction algorithm of

followings regarding the project

>>>>>>>>>>>>>>>>>>>>>>>>>
   1. ClusterMonitor class passes the calculated

   values from the CEP. This value passing happens after

   org.apache.stratos.messaging.event          happens.

   2. RuleTasksDelegator class calculates the

   prediction values using the values(Ex gradient) from the CEP

   3. The classes in the package

   org.apache.stratos.cep.extension deals with the analysis of data in the

   real time and publish the relevant summarized health stats, which are

   needed for the autoscaling.
>>>>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>>>>>
So according to my understanding, I need to modify

above mentioned classes, in order to implement the curve fitting for

statistics prediction.

Furthermore,for this project, we can use the

regression implementation of CEP 4.0, which is expected to be released on

May 15th according to WSO2 public jira. I am planning to do a feasibility

study for the first two weeks of the project, where we can explore other
