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']
