Credentials
To use Capacity Advisor, to collect data, and to run reports, you must have credentials (a valid
user name and password) and appropriate toolbox authorization on systems where you plan to
use Capacity Advisor. For specifics about setting up user authorizations, see the “User

Dependencies
Data collection requires that credentials for each managed server be configured in HP Systems
Insight Manager.
• WBEM/WMI credentials must be configured for all Windows servers, and HP-UX servers. For
agentless data collection on Windows systems, the WBEM/WMI credentials must be set to
Administrator level. WBEM certificate authentication is supported for HP-UX servers.
• SSH credentials (user-based, host-based key, or by certificate) must be configured for all Linux
servers. Linux agentless data collection does not require root-level access. Systems Insight
Manager privilege elevation is supported on HP-UX and Linux servers using a single user
account with sudo or powerbroker with no password required.
• The Windows or Linux managed node can be configured for agentless data collection by
running the managed system setup wizard. Administrator or root level permission on the CMS
is required to configure agentless collection on the CMS.
• Insight Control virtual machine management is required to collect data from ProLiant/x86-based
hypervisors and their VMs and for Hyper-V VMs.

When upgrading or reinstalling software used with Capacity Advisor, there are different
considerations and procedures to follow specific to the operating systems underlying the CMS or

guides can be downloaded from http://www.hp.com/go/insightdynamics/docs.
