List/Dictionary - Combine elements based on item value

[Adam McGill]

Hello,

Basically want to add the items of net_interface into aggregate_info or create new list/dictionary based on key value of node_name.  Looking for assistance on how i can achieve this please and thank you.

Outcome of what want it listed below.

list called: aggregate_info

{

  "name": "agg_Data1_Cluster01",

   "node_name": "TEST_NA_CLUSTER_01-01",

   "percent_used_capacity": "46",

   "size_available": 8141263818752,

   "size_avaliable_80%": 5122753242726,

   "size_total": 15092552880128,

   "size_total_80%": 12074042304102,

   "size_used": 6951289061376

},

{

   "name": "agg_Data1_Cluster02",

   "node_name": "TEST_NA_CLUSTER_01-02",

   "percent_used_capacity": "34",

   "size_available": 5116275568640,

   "size_avaliable_80%": 3561215869747,

   "size_total": 7775298494464,

   "size_total_80%": 6220238795571,

   "size_used": 2659022925824

}

list called: net_interface

{

    "address": "XX.XXX.X.XXX",

    "address4oct": "224",

    "data_protcol": "none",

    "failover_group": "Management",

    "node_name": "TEST_NA_CLUSTER_01-01",

    "role": "node_mgmt",

    "vserver": "TEST_NA_CLUSTER_01"

},

{

    "address": "XX.XXX.X.XXX",

    "address4oct": "226",

    "data_protcol": "none",

    "failover_group": "Management",

    "node_name": "IQ-REG_NA_CLUSTER_01-02",

    "role": "node_mgmt",

    "vserver": "TEST_NA_CLUSTER_01"

}

Out Come want:

Dictionary called: aggregate_info (original) or new name

{

  "name": "agg_Data1_Cluster01",

   "node_name": "TEST_NA_CLUSTER_01-01",

   "percent_used_capacity": "46",

   "size_available": 8141263818752,

   "size_avaliable_80%": 5122753242726,

   "size_total": 15092552880128,

   "size_total_80%": 12074042304102,

   "size_used": 6951289061376

   "address": "XX.XXX.X.XXX",

   "address4oct": "224",

   "data_protcol": "none",

   "failover_group": "Management",

   "role": "node_mgmt",

   "vserver": "TEST_NA_CLUSTER_01"

},

{

   "name": "agg_Data1_Cluster02",

   "node_name": "TEST_NA_CLUSTER_01-02",

   "percent_used_capacity": "34",

   "size_available": 5116275568640,

   "size_avaliable_80%": 3561215869747,

   "size_total": 7775298494464,

   "size_total_80%": 6220238795571,

   "size_used": 2659022925824

   "address": "XX.XXX.X.XXX",

   "address4oct": "226",

   "data_protcol": "none",

   "failover_group": "Management",

   "role": "node_mgmt",

   "vserver": "TEST_NA_CLUSTER_01"

}

Adding further to above, i know i can get the value i want by doing this.

- debug:

        msg: "{% for address in net_interface if address.node_name == 'IQ-REG_NA_CLUSTER_01-01' %}{{ address.address }}{% endfor %}"

Anyway to add that logic when creating the aggregate_info list. for example, but when trying to do this i get a template error.  Don't know if its possible to do or i am missing something with my syntax.

- name: Get_Aggregate_Info

      #no_log: True

      set_fact:

        aggregate_info: "{{ aggregate_info | 

          d([]) + [ {

          'name': item.value.aggregate_name, 

          'size_available': item.value.aggr_space_attributes.size_available | int,

          'size_avaliable_80%': (((item.value.aggr_space_attributes.size_total | int) * 0.8) - (item.value.aggr_space_attributes.size_used | int)) | round | int,

          'size_total': item.value.aggr_space_attributes.size_total | int,

          'size_total_80%': ((item.value.aggr_space_attributes.size_total | int) * 0.8 ) | round | int,

          'size_used': item.value.aggr_space_attributes.size_used | int,

          'node_name': item.value.nodes.node_name,

          'percent_used_capacity': item.value.aggr_space_attributes.percent_used_capacity

          'test': {% for address in net_interface if address.node_name == item.value.nodes.node_name %}{{ address.address }}{% endfor %}

          } ] }}" 

      with_items: "{{ netapp_info.ontap_info.aggregate_info | dict2items }}"

      when:

        - ('agg_' in item.value.aggregate_name)

Figured out how to merge the lists based on values in each list.  

- name: merge lists

      set_fact:

        merged_list: "{{ merged_list|default([]) + [{ 

          'name': item[0].name, 

          'size_available': item[0].size_available,

          'size_avaliable_80': item[0].size_avaliable_80,

          'size_total': item[0].size_total,

          'size_total_80': item[0].size_total_80,

          'size_used': item[0].size_used,

          'node_name': item[0].node_name,

          'percent_used_capacity': item[0].percent_used_capacity,

          'current_node': item[1].current_node,

          'address': item[1].address,

          'address4oct': item[1].address4oct,

          'failover_group': item[1].failover_group,

          'data_protcol': item[1].data_protcol| default(''),

          'role': item[1].role,

          'vserver': item[1].vserver

          }] }}"

      when: "item[0].node_name == item[1].current_node"

      loop: "{{ query('nested', aggregate_info, net_interface) }}"
