Ilia Shakitko commented on CLOUDSTACK-721:
------------------------------------------
Here is a suggestion of my collegue, how to make it works (all changes made in
VirtualNetworkApplianceManagerImpl.java)
http://pastebin.com/w2tFu21F
But the point is to understand is it bug, or feature changes in CS 4.0.0
Thanks

> Key: CLOUDSTACK-721
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-721
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Usage
> Affects Versions: 4.0.0
> Reporter: Ilia Shakitko
> Labels: network, usage, user_statistics
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> The usage server can give the system usage of each virtual machine (such as
> running time, ServiceOffering, IPAddress, Volume, Template, ISO, Port
> Forwarding Rule, Network offering), except the network bytes sent/received.
> This problem only exists in CloudStack 4.0. In CloudStack 3.0.2, the usage
> server works well.
> Analysis steps:
> 1. Check the CloudStack logs
> We can get the logs in /var/log/cloud/management/management-server.log

> From Step 1 to Step 4, we can conclude that the inconsistent of data
> initialization and data processing procedure is the root cause of this
> problem.
> ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
> We notice that there are some changes of the data processing procedure
> between CloudStack 3.0 and CloudStack 4.0. That's why this problem only
> exists in CloudStack 4.0.0
> Does anybody know why this change was made or it's just a bug?
