Ansible Nested lists into jinja template - ansible

Question

I am attempting to past a nested list into jinja to create a configuration file for Telegraf using the SNMP input plug-in.
So far I have been able to parse the following simple list into a suitable configuration file.
List:
- name: CpuUsage
oid: 1.3.6.1.4.1.5951.4.1.1.41.1.0
- name: mgmt_CPU
oid: 1.3.6.1.4.1.5951.4.1.1.41.6.1.2.8.77.103.109.116.32.67.80.85
- name: MemUsage
oid: 1.3.6.1.4.1.5951.4.1.1.41.2.0
- name: TotRxMbits
oid: 1.3.6.1.4.1.5951.4.1.1.43.27.0
- name: TotTxMbits
oid: 1.3.6.1.4.1.5951.4.1.1.43.30.0
- name: httpTotRequestsRate
oid: 1.3.6.1.4.1.5951.4.1.1.48.76.0
- name: tcpCurClientConnEstablished
oid: 1.3.6.1.4.1.5951.4.1.1.46.12.0
- name: tcpCurServerConnEstablished
oid: 1.3.6.1.4.1.5951.4.1.1.46.10.0
- name: tcpCurClientConnClosing
oid: 1.3.6.1.4.1.5951.4.1.1.46.9.0
into the following config:
[[inputs.snmp.field]]
name = "CpuUsage"
oid = "1.3.6.1.4.1.5951.4.1.1.41.1.0"
conversion = "int"
[[inputs.snmp.field]]
name = "mgmt_CPU"
oid = "1.3.6.1.4.1.5951.4.1.1.41.6.1.2.8.77.103.109.116.32.67.80.85"
conversion = "int"
[[inputs.snmp.field]]
name = "MemUsage"
oid = "1.3.6.1.4.1.5951.4.1.1.41.2.0"
conversion = "int"
[[inputs.snmp.field]]
name = "TotRxMbits"
oid = "1.3.6.1.4.1.5951.4.1.1.43.27.0"
conversion = "int"
[[inputs.snmp.field]]
name = "TotTxMbits"
oid = "1.3.6.1.4.1.5951.4.1.1.43.30.0"
conversion = "int"
[[inputs.snmp.field]]
name = "httpTotRequestsRate"
oid = "1.3.6.1.4.1.5951.4.1.1.48.76.0"
conversion = "int"
[[inputs.snmp.field]]
name = "tcpCurClientConnEstablished"
oid = "1.3.6.1.4.1.5951.4.1.1.46.12.0"
conversion = "int"
[[inputs.snmp.field]]
name = "tcpCurServerConnEstablished"
oid = "1.3.6.1.4.1.5951.4.1.1.46.10.0"
conversion = "int"
[[inputs.snmp.field]]
name = "tcpCurClientConnClosing"
oid = "1.3.6.1.4.1.5951.4.1.1.46.9.0"
conversion = "int"
Where I am stuck is with the following list of lists
netscaler_citrix_vserver:
- name: name
oid: NS-ROOT-MIB::vsvrName
is_tag: "true"
- name: fullName
oid: NS-ROOT-MIB::vsvrFullName
is_tag: "true"
- name: requests
oid: NS-ROOT-MIB::vsvrTotalRequests
- name: state
oid: NS-ROOT-MIB::vsvrState
- name: servicesUp
oid: NS-ROOT-MIB::vsvrCurServicesUp
netscaler_citrix_vservice:
- name: vserver
oid: NS-ROOT-MIB::vserverFullName
is_tag: "true"
- name: vservice
oid: NS-ROOT-MIB::vsvrServiceFullName
is_tag: "true"
- name: hits
oid: NS-ROOT-MIB::vsvrServiceHits
I've tried a number of variations, but each proving unsuccessful. I'm trying to get the following output:
[[inputs.snmp.table]]
name = "netscaler_citrix_vserver"
# oid omitted, to allow collection of specific columns only
[[inputs.snmp.table.field]]
name = "name"
oid = "NS-ROOT-MIB::vsvrName"
is_tag = true
[[inputs.snmp.table.field]]
name = "fullName"
oid = "NS-ROOT-MIB::vsvrFullName"
is_tag = true
[[inputs.snmp.table.field]]
name = "requests"
oid = "NS-ROOT-MIB::vsvrTotalRequests"
[[inputs.snmp.table.field]]
name = "state"
oid = "NS-ROOT-MIB::vsvrState"
[[inputs.snmp.table.field]]
name = "servicesUp"
oid = "NS-ROOT-MIB::vsvrCurServicesUp"
[[inputs.snmp.table]]
name = "netscaler_citrix_vservice"
# oid omitted, to allow collection of specific columns only
[[inputs.snmp.table.field]]
name = "vserver"
oid = "NS-ROOT-MIB::vserverFullName"
is_tag = true
[[inputs.snmp.table.field]]
name = "vservice"
oid = "NS-ROOT-MIB::vsvrServiceFullName"
is_tag = true
[[inputs.snmp.table.field]]
name = "hits"
oid = "NS-ROOT-MIB::vsvrServiceHits"
Basically I need to reference the top-level entry and for each top-level entry list the sub-level entries also.
Any help would be appreciated.
the code used to create the first list is pretty straightforward, as follows:
[[inputs.snmp.field]]
name = "{{ item.name }}"
oid = "{{ item.oid }}"
{% endfor %}
for the SNMP table code I've resorted to explicitly declaring the table name as follows:
[[inputs.snmp.table]]
name = "netscaler_citrix_vserver"
{% for item in netscaler_citrix_vserver %}
[[inputs.snmp.table.field]]
name = "{{ item.name }}"
oid = "{{ item.oid }}"
{% if item.is_tag is defined %}
is_tag = {{item.is_tag}}
{% endif %}
{% endfor %}
[[inputs.snmp.table]]
name = "netscaler_citrix_vservice"
{% for item in netscaler_citrix_vservice %}
[[inputs.snmp.table.field]]
name = "{{ item.name }}"
oid = "{{ item.oid }}"
{% if item.is_tag is defined %}
is_tag = {{item.is_tag}}
{% endif %}
{% endfor %}

Answer 1

Of course as soon as I posted the answer from another question in related questions popped up. Resolved with the following code
{% for input_snmp_table in input_snmp_tables recursive %}
[[inputs.snmp.table]]
name = {{ input_snmp_table.table_name }}
{% for input_snmp_table_fields in input_snmp_table.input_snmp_table_fields %}
[[inputs.snmp.table.field]]
name = "{{ input_snmp_table_fields.name }}"
oid = "{{ input_snmp_table_fields.oid}}"
{% if input_snmp_table_fields.is_tag is defined %}
is_tag = {{input_snmp_table_fields.is_tag}}
{% endif %}
{% endfor %}
{% endfor %}```
