 - Issues with rabbit ?
    - flap when rolling out agent / deploying new agent version
        - even crash on big regions
    - network flap / rabbit partition
        - pause-minority 
+   - reset cluster was ... the solution 
+
+- What's going on with rabbit ?
+    - reproduce workload with rabbit perftest
+    - oslo.metrics 
+    - rabbitmq exporter / grafana dashboards
+    - smokeping between nodes
+
+=> we identified issues were mostly related to neutron 
+    - rabbit flap flood resources to agents
+
+- How ? RPC implementation in Openstack: aka oslo.messaging
+    - pub/sub
+        - RPC server: setup endpoints / queues / listeners
+            - topic, fanout mechanism
+        - publish: rpc provided methods
+            - call
+            - cast
+            - cast / fanout=true
+    - notifications: kafka
