Dear Nick and others

Thank's for answer me so quickly. I do some test to check  out your code.

You're right in using cf-promises command to get back this variables.

I do a bundle to test it, and have some good results:

bundle agent network
{

   vars:
       "sys_interfaces" slist => getindices("sys.interfaces");

       "sys_interfaces_data_keys" slist => getindices( 
"sys.interfaces_data" );

       "sys_ipv4" slist => getindices("sys.ipv4");

   reports:

     any::
       "Value of sys_interfaces $(sys_interfaces)";

       "Value of sys_interfaces_data $(sys_interfaces_data_keys)";

       "value of sys_ipv4: $(sys_ipv4)";

}

That get me this report:


R: Value of sys_interfaces_data lo
R: Value of sys_interfaces_data enp1s0
R: Value of sys_interfaces_data enp7s0
R: Value of sys_interfaces_data enp8s0
R: Value of sys_interfaces_data virbr0
R: value of sys_ipv4: enp8s0
R: value of sys_ipv4: lo
R: value of sys_ipv4: enp7s0
R: value of sys_ipv4: virbr0
R: value of sys_ipv4: enp1s0

So, "sys.interfaces_data" is the good variable. But i've got an issue 
that i could no explain: Why could i no get the list of the 
sys.interfaces name? With the variable "sys_interfaces", I've get 
anything, as show before.

But if i wirte directly in report as this:

   reports:

     any::
       "Value of sys_interfaces $(sys.interfaces)";

I get back this report:

R: Value of sys_interfaces enp1s0
R: Value of sys_interfaces enp7s0
R: Value of sys_interfaces enp8s0
R: Value of sys_interfaces virbr0

I could not understand why the variable definition of sys_interfaces get 
back a null list...

Hope that someone could help me.

Regards
