how can get the signal strenght from a wireless mikrotik device?. For exemple, for puting it in the device appearance at label like a Device variable. It's possible? Any idea?
Yes, this is possible chikito.
I achieve this using OID, you have to select it in the item.
This is an example of what it looks like in one of my devices.
Result is something like:
cpu: 10% disk: 40%
There are probably some other ways, but thats how i've achieved it.
