Pasos de configuración: Monitor a single SNMP value
On the device, enable SNMP and check that the community or the v3 user may read the object (the SNMP view must grant its branch).
In DumbMonit, enter the device address, then the community or the v3 user.
Fill in the object (OID) with its instance suffix, for example 1.3.6.1.2.1.1.3.0.
Optional: set a minimum and a maximum, or an expected text, to be warned when the value drifts.
Ojo. An object the agent does not know, or that its SNMP view hides, is reported down with the reason not_found.
