API doc for iControl?

I found what I'm looking for: https://devcentral.f5.com/wiki/iControl.LocalLB__Pool__get_member_session_status.ashx

 

 

However struggling with the above - using version 11.0 for an ltm os.

 

 

https://devcentral.f5.com/wiki/iControl.LocalLB__Pool__get_member_session_status.ashx for example - what kind of input is it expecting, and in what format (for ruby).

 

 

I tried

 

pools = "/Common/my_pool_name"

 

pool_member_addresses = bigip['LocalLB.Pool'].get_member_session_status(pools, { 'address' => "10.0.20.151", 'port' => "8080"})

 

 

but that didn't seem to do the trick.

 

 

Can anyone provide a ruby example of how to disable a node from a pool given a pool name and an ip address?

I haven't checked the code to disable the member from the pool, but do have a snippet where i disable the node itself (after I add it).

 

 

This is using 11.2 F5 iControl GEM.

 

 

 Create node if it doesn't already exist.
unless bigip['LocalLB.NodeAddressV2'].get_list.include? '/Common/' + node_name
  bigip['LocalLB.NodeAddressV2'].create([ node_name ], [ node_address ], [0])
  puts '   Created node "' + node_name + '" with IP Address "' + node_address + '"...'
   After we add a member... let's disable the node state
  bigip['LocalLB.NodeAddressV2'].set_session_enabled_state([ node_name ], [ "STATE_DISABLED" ])
  puts '   Node "' + node_name + '"set to disabled..."'
else
   puts '   Node "' + node_name + '" already exists! Not Added.'
end

 

 

Hope it helps.

 

 

Darrell,

 

That's useful. Thanks. I was looking more to figure out syntax. I think if I get enough examples I can work with I can figure out what I need to do.

 

 

One thing that I was struggling with is pool_member_addresses = bigip['LocalLB.Pool'].get_member_v2([pools])

 

 

That returns an array of objects, and if I inspect that array, I get the addresses and ports and soap mapping objects, but I don't know how to actually just get the value of addresses.

 

 

Disclaimer - I'm very new to ruby - so it might be something easy that I'm just overlooking. Any ideas there?

Here's a snippet of my updated f5-node-initiator (this was the one good example of pool/node manipulation using the Ruby iControl).

 

 

collect list of existing pool member definitions

 

pool_members = bigip['LocalLB.Pool'].get_member_v2([ pool_name ])[0].collect do |pool_member|

 

pool_member['address'] + ':' + pool_member['port'].to_s

 

end

 

 

don't attempt to add member if it already exists

 

unless pool_members.include?('/Common/' + node_name + ':' + node_port.to_s)

 

bigip['LocalLB.Pool'].add_member_v2([ pool_name ], [[{ 'address' => node_name, 'port' => node_port.to_i }]])

 

puts ' Node "' + node_name + ':' + node_port + '" added to "' + pool_name + '" pool...'

 

else

 

puts ' Node "' + node_name + ':' + node_port + '" already exists in "' + pool_name + '". Not added.'

 

end

Hope it helps.
