[jira] [Commented] (STRATOS-108) Load Balancing Statistics Reporting Interface and its implementation for CEP

    [ https://issues.apache.org/jira/browse/STRATOS-108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13800178#comment-13800178 ] 

Nirmal Fernando commented on STRATOS-108:
-----------------------------------------

Load balancer and CEP is communicating via Observer pattern, where a statistics collector in LB acting as the subject and CEPs act as Observers. Stats collector periodically notifies all the registered observers, so that they can act upon changes.

Fixed in 19d493a0a63b578fb23466de3eedf4e2be8b26f9 and 8c0597c51fe78d026ef27f9b931023eea6502711

> According to the new architecture load balancers need to report statistics with respect to the incoming request load and member availability to Complex Event Processor (CEP). To make this communication generic the idea of this task is to design an interface and implement it for different types of receivers.
