How do I access the cpu %usage in this example? I'm getting an error no matter what I try.

[Marcos Georgopoulos]

Hi, 

I am using the Napalm module with Ansible and using its get_facts module to obtain some basic information from the device. The relevant output is below, 

"ansible_facts": {
     "napalm_environment": {
                "cpu": {
                    "0": {
                        "%usage": 0.0
                         }
                       },

Using the debug module for troubleshooting, the following

 

- name: print data
      debug:
        msg: "{{ result.ansible_facts.napalm_environment.cpu }} "

outputs the following:

 "msg": {
        "0": {
            "%usage": 0.0
        }
    }

The question is how do I access the value for the key "%usage".

 

- name: print data
      debug:
        msg: "{{ result.ansible_facts.napalm_environment.cpu.0}} "

 

- name: print data
      debug:
        msg: "{{ result.ansible_facts.napalm_environment.cpu.'0'. }} "

 

 The error was: dict object has no element 0

Many thanks

You can access the first element using result.ansible_facts.napalm_environment.cpu[0].%usage or so.

This should work

result.ansible_facts.napalm_environment.cpu['0']['%usage']
