Setting LocalLB.NodeAddress states

Cindy,

 

 

Although the mentioned methods sound similar, there are some subtle differences in how they're used.

 

 

LocalLB.NodeAddress.set_session_enabled_state

 

LocalLB.NodeAddress.get_session_enabled_state

 

 

The "set" method is used to enable/disable new sessions to be established for the specified node addresses. The "get" method is used to retrieve the value of the configured state that you set with the "set" method.

 

 

LocalLB.NodeAddress.get_session_status

 

 

This method is used to get the actual, reflected status of the sessions for the specified node addresses. For node addresses, the returned status will likely be either enabled (0), disabled (1), or forced disabled (2). But when you call LocalLB.PoolMember.get_session_status, the returned status also takes into consideration the status of the parent object, (for pool members, the parent objects are the node addresses), hence any of the 4 values is possibly returned.

 

 

Now, if you really want to explicitly set the status of the node addresses, or pool members yourself (i.e. bringing them UP or down rather than letting the health monitoring system do it for you), you can override it by calling either

 

 

LocalLB.NodeAddress.set_monitor_state or

 

LocalLB.PoolMember.set_monitor_state

 

 

You can then call the "get_monitor_status" in either NodeAddress or PoolMember interface to get the actual, reflected monitor status of the respective objects.

 

 

Hope this helps.
