Network bandwidth metering support provides you with network usage data for the appliances running on your grids. You can use this data to bill your customers for the amount of network bandwidth used by their applications.
The external network usage statistics are collected every 12 minutes by the metering client. The following network usage data is collected for each external interface:
Metered traffic is the network traffic that CA AppLogic® "meters". Metered traffic statistics account for network traffic that actually leaves and enters a grid (to or from an external system outside of the grid itself). The following is a list of network traffic that is not metered:
Network traffic between two appliances on separate grids and the grids are in different datacenters is metered. The remote MAC address is used to determine if a packet is metered.
Also, once a component is stopped, the statistics are retrieved and written to the controller's metadata volume in /var/applogic/stats. This is to account for the external network usage since the last metering collection. The subsequent metering collection will retrieve this data and include it in the next collection data.
Important: If a server crashes, the external network usage data since the last metering collection period is lost for all components that were running on that server.
In the daily metering reports that is sent to the metering server, the metering client includes the metered statistics for each appliance. If the VLAN ID is set on the appliance, the VLAN ID is included in the report too. This data is available through the metering server for each application and VLAN.
