Introduction

Let user know the total, external, internal network I/O data traffic for individual virtual machine.

...

For now, user can get a external data traffic for a virtual network from virtual router. Moreover, as
As user we also want to know the data traffic for a virtual machine, including external and internal data traffic.

Target Branch

4.2

Feature Specifications

• Agent manager get and report the total and external network I/O network usage of VM from hypervisor.
• Agent managet manager get and report the network I/O external network usage of VM from virtual router.
• store the network network I/O statistics into db
• analyse the network usage in usage server.

Use cases

TBD

Architecture and Design description

• add vm_statistics_network table in cloud database.
• Agent manager get the total I/O from hypervisor.
• Agent manager get the external I/O from virtual router.
• change APIs
• change cloud-usage server

Web Services APIs

...

• deal with deployVM, destroyVM, stopRouter, startRouter, restartNetwork.

Hypervisors

KVM
