Is it possible to set the "Node Name" in AS3 Pool_Member

[zongzw]

Hi

I'm implementing an external monitor in which I do a HTTP request to the member to check if the member is available.

In this case, I need to check the hostname instread of "AddressDiscovery"-ed auto<IP>, because http get IP may get 404. For example: http://www.example.org -> 200, http://93.184.216.34 -> 404.

So I need to know the hostname instead of resolved IP that bigip gives to me in monitor checking.

A way to get the hostname is the node name:

'NODE_NAME': '/Common/www.example.org' instead of 'NODE_NAME': '/Common/_auto_93.184.216.34'

In general AS3 declaration, it always resolve the passed hostname to _auto<IP>:

                "web_pool-1637673434": {
                    "class": "Pool",
                    "members": [
                        {
                            "servicePort": 80,
                            "hostname": "www.example.org",
                            "addressDiscovery": "fqdn",
                            "autoPopulate": true
                        }
                    ]
                }

How can I set node_name?

More information about context of running external monitors FYI:

external monitor arguments:

['/config/ex_monitors/my_monitor_executable', '::ffff:93.184.216.34', '80', '/']

This is related to #161. For now I am not considering this a duplicate since this issue focuses on FQDN, while #161 focuses on static nodes.
