Description (partial)


Since day one, vManage does not provide a way to replicate the idle timeout of a given client/API session across a cluster.

On load balancing scenario, if requests are distributed across servers in the cluster, it is possible that a server will not receive them in a frequency high enough to avoid idle timeout to kick in, and delete the session 
For example, if the application doing API queries, launches one every 20 minutes, across a server of 3 nodes, after 30 min, the first node will have expired

Per engineering feedback, this is day one behavior

API queries on low frequency
Load balancer in front of the vManage cluster

API frequency per server is lower than 30 min
