Hi Bryan,

You can see neutron driver's action with 'openstack congress datasource 
actions show' command.  It shows all execution method supported by 

btw, the prefix of reaction policy rule is datasource *name*. If you 
initialize openstack like devstack, the datasource name for neutron is 
not neutron but neutronv2.

best regard,
