The Credentials system stores login, community string, and connection string information for Windows (WMI Active Monitors, WMI Performance Monitors, and the Web Task Manager), SNMP v1, 2, and 3 devices in the WhatsUp Gold database, and ADO database connection string information.
Credentials are configured in the Credentials Library (found on the web interface menu in the WhatsUp section of the GO menu at Configure > Credentials Library) and used in several places throughout the application. They can be associated to devices in Device Properties > Credentials, or through the Credentials Bulk Field Change option.
A device needs SNMP credentials applied to it before SNMP-based Active Monitors will work. Similarly, NT Service Checks must have Windows credentials applied, and WhatsUp Gold database monitors require ADO connection information.
