1. timeout when publishing to ifmap-server (mapclient.call())
   when timeout happens keep retrying
2. ifmap-server code needs to inspect healthcheck object publish and if it misses n of them, exit() OR
     config-nodemgr keeps reading healthcheck object from ifmap-server and if it can't read in n secs or value is stale, kill ifmap-server
3. control-node keeps reading healthcheck object from ifmap and it sees stale, move to a new ifmap-server
4. ifmap-publish-greenlet enqueue finds q-full, no change from current

Following steps are needed in a VM environment for contrail all-in-one (assuming trusty r201)

sudo apt-get –y install curl

prep right hostname without this fab get_all_time fails

echo "127.0.0.1 $(hostname)" >>  /etc/hosts

prep keys WARNING do not do this if there is already id_rsa key.

[Cleanup-Steps]
0. Deleted all service-instances, VMs, networks.
1. service supervisor-webui stop on all contrail controllers
2. service supervisor-analytics stop on all contrail controllers
3. service supervisor-config stop on all contrail controllers
4. service supervisor-control stop on all contrail controllers
5. service supervisor-database stop on all contrail controllers
6. service zookeeper stop on all contrail controllers
7. mv /var/lib/cassandra /var/lib/cassandra.old
8. mv /var/lib/zookeeper/version-2 /var/lib/zookeeper/version-2.old

1. Install 3 new servers with base OS same s4,5,6
2. Install analytics and database packages on the 3 new servers s4,5,6
   • which packages kafka too?
3. service supervisor-analytics stop; service cassandra stop; kafka?
4. Determine whether old analytics DB is to be migrated or built anew 4.1 To be anew 4.1.1 service supervisor-analytics stop on s1,2,3 4.1.2 provision cassandra.yaml and cassandra-env.sh to have a cluster of s4,5,6 4.1.3 provision analytics processes - discovery-ip should be VIP. 4.1.4 service supervisor-analytics start; service cassandra start; kafka?
