In WhatsUp Gold, credentials are used like passwords to limit access to a devices SNMP data. The credentials system supports SNMP v1, 2, and 3.
Credentials are configured and stored in Credentials Library (found on the web interface menu at Go > Configure > Credentials Library) and used in several places throughout the application. They can be assigned to devices in Device Properties > Credentials, or through the Credentials Bulk Field Change option.
Devices need SNMP credentials assigned to them before SNMP-based Active Monitors will work.
