But a coupling would still exist between the log textual format and the log parsing regexes, which would themselves be more complex to support multiple matches for each line and data extraction. Also, log processing introduces a delay between the triggering event and sending the data to StatsD.

Once created, you can associate a queue with a network. Then, when ports are created on that network they are automatically created and associated with the specific queue size that was associated with the network. Because one size queue for a every port on a network might not be optimal, a scaling factor from the nova flavor 'rxtx_factor' is passed in from Compute when creating the port to scale the queue."

For multiple-machine installation, the VLAN Network Mode requires a switch that supports VLAN tagging (IEEE 802.1Q). The tenant gets a range of private IPs that are only accessible from inside the VLAN. In order for a user to access the instances in their tenant, a special VPN instance (code named cloudpipe) needs to be created. Compute generates a certificate and key for the user to access the VPN and starts the VPN automatically. It provides a private network segment for each tenant's instances that can be accessed through a dedicated VPN connection from the Internet. In this mode, each tenant gets its own VLAN, Linux networking bridge, and subnet."
