Compilation of MIB files allows to display additional, non‑standard SNMP object branches (e.g., from less common hardware vendors) in the SNMP browser . Objects in the SNMP tree are stored in specific branches identified by OIDs.
Which information is available and in which branch depends on the manufacturer of the specific device and should be included in the device’s user manual.
In nVision, you can monitor values from the SNMP tree that are available as integers. Other available values, such as strings (string, octet string), will also be visible in the SNMP browser.
To configure SNMP monitoring for a selected device in nVision:
Enable and configure SNMP in the management interface of the device.
Locate its icon in the nVision console, open device information window (double‑click the icon), and go to the SNMP tab.
-
Select "SNMP‑manageable device" checkbox, then click the Configure login data link.
-
In the SNMP Login Data window, enter the credentials configured in step 1. If the credentials are correct, the login test will end with the message: "SNMP community test succeeded".
-
To add performance counters:
-
go to "Performance \ Counters" tab, click the ( + ) icon,
select SNMP counter type,
specify the OID of the counter you want to monitor (or select fields from the SNMP browser table).
-
If the desired branch is not visible in the nVision SNMP browser, it may be necessary to compile the MIB file downloaded from the device manufacturer’s website.
