Hi, I am looking for a common RPC message trace mechanism in oslo_messaging. This message trace mechanism needs to be common to all drivers. Currently some documentation mentions that oslo_messaging_amqp.trace can activate the message trace (say, http://docs.openstack.org/liberty/config-reference/content/networking-configuring-rpc.html). But it seems that this oslo_messaging_amqp.trace is only available to the Proton driver. Do I miss any existing common RPC message trace mechanism in oslo? If there is no such mechanism, I would propose to create such a mechanism for oslo. Any response is appreciated. Thanks.
