SNMP value (single OID)
Reads one SNMP object and checks its value against a range or a text.
Product descriptions are in English, as in the product. The page labels follow your language.
What DumbMonit watches
Typical use. One SNMP object: sensor, UPS status, version string, with bounds or expected text
Examples
- A temperature or humidity sensor
- A UPS status or battery level
- A version string or a firmware flag
- A counter exposed by a Net-SNMP extend script
How it connects
What you need
- SNMP v1 / v2c (community)The simplest form: one shared word, sent unencrypted.
- SNMP v3 (user, authentication, privacy)Authenticated and encrypted. Needs a USM user on the device.
Default port: 161
Setup steps: 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.
Heads-up. An object the agent does not know, or that its SNMP view hides, is reported down with the reason not_found.
