Configure metering agent

Procedure 7.14. To install the metering agent and configure the node

1. Install the agent by running:

   # apt-get install neutron-metering-agent

   	Package name prior to Icehouse
   	In releases of Neutron prior to Icehouse, this package was named neutron-plugin-metering-agent.

2. If you use one of the following plugins, you need to configure the metering agent with these lines as well:

   • An OVS-based plug-in such as OVS, NSX, Ryu, NEC, BigSwitch/Floodlight:

     interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

   • A plug-in that uses LinuxBridge:

     interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver

3. To use the reference implementation, you must set:

   driver = neutron.services.metering.drivers.iptables.iptables_driver.IptablesMeteringDriver

4. Set this parameter in the neutron.conf file on the host that runs neutron-server:

   service_plugins = neutron.services.metering.metering_plugin.MeteringPlugin
