The Credentials system stores the applicable login, community string, or connection string information for the following devices and applications:
Credentials are configured in the Credentials Library (located on the Admin tab under Credentials Library) and used in several places throughout the application. They can be associated with devices in the Device Properties dialog (right-click a device, select Properties > Credentials), or through the Credentials Bulk Field Change option, accessed by right-clicking a group of devices in a device list or map.
A device needs SNMP credentials applied to it in order for SNMP-based active monitors to work. Similarly, NT Service Checks must have Windows credentials applied, and WhatsUp Gold database monitors require ADO connection information.
VMware vCenter, and ESXi devices require VMware credentials to access system performance counters.
WhatsConfigured plug-in requires either an SSH or Telnet connection to gather configuration data and to perform various task scripts.
