Change Response/Idle timeout value for application profile of Virtual Servers in NSX-T

Products

• VMware NSX

Issue/Introduction

• Application profiles are associated with virtual servers to enhance load balancing network traffic and simplify traffic-management tasks.
• The Response timeout value for application profile states on how long the load balancer waits for Server HTTP Response before it stops and closes the connection to the pool member and retries the request to another server.
• Idle timeout value for how long client idle connections remain before the load balancer closes them (FIN).

Environment

VMware NSX 

Resolution

The default response timeout value of application profile is 60 seconds

The default idle timeout value of application profile is 1800 seconds

and the below document can be referred to set the same in NSX ui:

Additional Information

The maximum value for response timeout of application profile is 2147483647.

If the response timeout value is increased to bigger value, the connection number might reach the maximum connection limit for each Load Balancer and the new connections will be rejected based on that.
