Hello all,

I can see the alarm in alarm-history. However, no actions are triggered.
Could you please help me out here ?

Here is the alarm-show :

In your load balancer yaml, i.e lb_server.yaml Add the following:

Under 'parameters' add network id

parameters:
private_net_id:
    type: string
    default: XXXX


And under resources:

member:
    type: OS::Neutron::PoolMember
    properties:
      pool_id: {get_param: pool_id}
      address: {get_attr: [server, first_address]}
      protocol_port: 80
  server_port:
    type: OS::Neutron::Port
    properties:
      network_id: { get_param: private_net_id } => add the network id.
      fixed_ips:
        - subnet_id: { get_param: subnet_id }

This should help you specify the network in which you want to plug in your VMs.

Deepthi
