Unique Identifier Settings
Unique Identifier Settings define how ServiceOps determines whether a discovered device is new or already exists in the CMDB. When a discovery scan runs, the system compares the device's identifier values against existing asset records. If a match is found, the existing asset is updated. If no match is found, a new asset is created. Configuring the right identifiers per protocol prevents duplicate asset records and keeps your CMDB accurate.
Prerequisites
- Admin access to the ServiceOps portal.
Configuration Steps
To configure unique identifier settings, navigate to Admin > Discovery & Agents > Unique Identifier Settings.
Configuration Parameters
The page has the following fields:
| Field | Description |
|---|---|
| Unique Identifier for SSH | Select the identifiers based on which assets are added to ServiceOps. This prevents duplicate assets from being added. If an asset with the same identifiers already exists, its details are updated. For the MAC Address identifier, the system checks multiple Hardware Asset Network Adapter MAC Addresses and either updates the existing asset or creates a new one. Applicable to Linux and macOS machines. |
| Unique Identifier for WMI | Select the identifiers based on which assets are added to ServiceOps. This prevents duplicate assets from being added. If an asset with the same identifiers already exists, its details are updated. Applicable to Windows machines only. |
| Unique Identifier for SNMP | Select the identifiers from the dropdown for the SNMP protocol. |
Once done, click Update to save the settings or Cancel to close without saving.
Example
Your organization uses SSH-based discovery for Linux servers. You configure Computer UUID as the unique identifier for SSH. When the same server is rediscovered after a hostname change, ServiceOps matches it by UUID and updates the existing asset record instead of creating a duplicate.
