load Balancer session timeout

VMware NSX version: 6.3.5.7119875

NSX Edges version: 6.3.5

There is one NSX server and two High Available Edge servers used for load balancing only. L7 load balancing is enabled.

vCenter server appliance version: 6.0.0 7037393

ESXi servers version: ESXi 6.0.0 6921384

The problem appeared in customer’s application where the end users were disconnected because of session timeout. when checked, found that the persistence expiration which was 5 minutes (the default). So changed it to 7200 seconds.

But when checked the edge server CLI command “show service load-balancer session l7” the output is different

- the “exp=” is maximum 5 minutes for any session.

Question:

Is the above setting for persistence expiration applied or not? And how can we verify it?

HI RAmSThakur

Please check if your LB Edges in HA are not in split brain.

Please use API to change values for persistence.

value 5 minutes indicated that there is no updated info on Edges from NSX UI.

Verify what UI shows in sessions

verify with API what sessions is actually

Compare them . 

using API can avoid UI issues and Split brain scenarios.

easy to do just query LB config , change the value of persistence and put t back
