UIM : snmpcollector : Unable to import device by Query Discovery Server

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

SNMP discovery (via UMP) is done for the following devices, but the "Query Discovery Server" in the SNMP collector probe does not create 2 profiles for both devices.

IP Address	Name
XXX.1YX.0.1DS	cisco1
XXX.1YX.0.1DS	cisco1

Environment

snmpcollector probe any version.

Cause

The discovery name (in this scenario, Sysname) is duplicated for those devices.
If DNS resolution for the device is not available, the SNMP collector will use Sysname for the profile name.
In the SNMP collector probe, the profile name must be unique.
Since the snmpcollector probe can't create 2 profiles with the same name, it does not import both.

Resolution

Add unique entry for these devices using local hosts file (Windows : Windows\System32\drivers\etc\hosts, Linux : /etc/hosts)
on the box where discovery_agent probe (for SNMP device discovery) is running.
For example, add the following entry to local hosts.

XXX.1YX.0.1DS     device_primary
XXX.1YX.0.1D1     device_secondary

Run SNMP discovery for those devices one more time, then device name in UMP will be reflected accordingly.
Once device name in UMP become unique, run Query Discovery Server in snmpcollector again.
