Hi Iranga, Actually Stratos uses separate CEP to analyse health statistics that are published from cartridges and services. Those analysed data are sent to the Autoscaler to take autoscaling decisions. You can find more information in [1].
In this DAS integration with Stratos, for the requirement of monitoring health statistics we need those summerized data from CEP. Therefore we need to publish those data from CEP to DAS. Other thing is DAS is an extension point in Stratos. Depend on the user requirement, he can use DAS for monitoring real time statistics.
