Netconf plugin commands without a key

[nitzan-tz]

Hi,

I am playing with jts_telegraf netconf plugin outside of openjts and with Prometheus plugin but I think that the following issue is a general one
For subscriptions without a key like for the command "show task memory" there are no results if I am not specifying a key (Just add [0] as a key)

For example,
the subscription below doesn't work

  [[inputs.netconf_junos.subscription]]
    name = "junos_task_mem"
    junos_rpc = "<get-task-memory-information></get-task-memory-information>"
    fields = [
             "/task-memory-information/task-memory-in-use-size:int",
             "/task-memory-information/task-memory-in-use-avail:int",
             "/task-memory-information/task-memory-max-size:int",                          
             "/task-memory-information/task-memory-max-avail:int",
             "/task-memory-information/task-memory-free-size:int",
             ]
    sample_interval = "60s"

This one works (See the extra [0])

  [[inputs.netconf_junos.subscription]]
    name = "junos_task_mem"
    junos_rpc = "<get-task-memory-information></get-task-memory-information>"
    fields = [
             "/task-memory-information[0]/task-memory-in-use-size:int",
             "/task-memory-information[0]/task-memory-in-use-avail:int",
             "/task-memory-information[0]/task-memory-max-size:int",                          
             "/task-memory-information[0]/task-memory-max-avail:int",
             "/task-memory-information[0]/task-memory-free-size:int",
             ]
    sample_interval = "60s"

And this is the output on the device

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/23.2R2.21-EVO/junos">
    <task-memory-information junos:style="brief">
        <task-memory-in-use-size>270656</task-memory-in-use-size>
        <task-memory-in-use-avail>1</task-memory-in-use-avail>
        <task-memory-max-size>393680</task-memory-max-size>
        <task-memory-max-avail>2</task-memory-max-avail>
        <task-memory-max-when>24/12/04 00:04:39</task-memory-max-when>
        <task-memory-free-size>15911548</task-memory-free-size>
    </task-memory-information>
    <cli>
        <banner></banner>
    </cli>
</rpc-reply>

Thanks
