Can you be a bit more specific on what you are requesting.

 

 

Do you already have a health monitor that you are using and are asking whether you can gracefully take down that node? If so, that's fairly simple with iControl. You can disable new sessions on the node and monitor the current sessions until it reaches zero. When that happens, you simply disable the node. Check out the PoolMember interface for the relevant methods.

 

 

If you are asking about whether an existing monitor will do this for you, I believe that if our built-in monitors report an error, they forcefully down the server to disallow all connections. For questions about how the existing monitors work, you'll need to contact F5 Product Technical Support.
