It is important to set up credentials for network devices before discovering new devices with . The Credentials system stores the applicable login, community string, or connection string information for network devices such as routers, switches, servers, virtual hosts, and other devices. Use the device credential library to add the following devices and application credential types to :

  • Windows (WMI Active Monitors, WMI Performance Monitors, and the Web Task Manager)
  • SNMP v1, 2, and 3 devices in the database
  • ADO database
  • VMware
  • Telnet
  • SSH

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 Credentials Bulk Field Change 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 database monitors require ADO connection information.

VMware vCenter, and ESXi devices require VMware credentials to access system performance counters.

plug-in requires either an SSH or Telnet connection to gather configuration data and to perform various task scripts. For more information, see Credentials Library.
