central management server (CMS)

A system in the management domain that executes the HP Systems Insight Manager software. All central operations within HP Systems Insight Manager are initiated from this system.

critical status

A state generated when HP Systems Insight Manager can no longer communicate to a managed system.

Desktop Management Interface (DMI)

An industry standard protocol, primarily used in client management, established by the DMTF. DMI provides an efficient means of reporting client system problems. DMI-compliant computers can send status information to a central management system over a network.

discovery

A feature within a management application that finds and identifies network objects. In HP management applications, discovery finds and identifies all the HP systems within a specified network range.

Domain Name Service (DNS)

A service that translates domain names into IP addresses.

enclosure

A physical container for a set of blades servers. It consists of a backplane that routes power and communication signals and additional hardware for cabling and thermal issues. It also hosts the CPU or server power supplies.

event

Information sent to certain users that something in the managed environment has changed. Events are generated from SNMP traps and are preconfigured in this release. HP Systems Insight Manager receives a trap when an important event occurs. Events are defined as:

  • Informational. Events of this type require no attention and are provided as useful information.

  • Normal. Events of this type indicate that this event is not a problem.

  • Minor. Events of this type indicate a warning condition that can escalate into a more serious problem.

  • Major. Events of this type indicate an impending failure.

  • Critical. Events of this type indicate a failure and signal the need for immediate attention.

hardware status

The operating state of SNMP-based systems. A hardware status is determined by polling SNMP information from the system. Status is defined as:

  • Critical. HP Systems Insight Manager can no longer communicate with the system. The system was previously discovered, but cannot be pinged. The system might be down, powered off, or no longer accessible on the network because of network problems.

  • Major. A problem exists.

  • Minor. The system is functioning but with errors.

  • Normal. The system is functioning correctly.

  • Unknown. HP Systems Insight Manager is not able to obtain management information about the system.

  • Disabled. 

identification

An aspect of the discovery process that identifies the management protocol and type of system.

Internet Protocol (IP)

Specifies the format of datagrams (packets) and the addressing scheme on a network. Most networks combine IP with Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.

Major status

Aggregate status information collected from the system that indicates one or more of the monitored subsystems are not operating properly which is impacting the system. Action should be taken immediately.

Minor status

Aggregate status information collected from the system that indicates one or more of the monitored subsystems are not operating properly which is impacting the system. Action should be taken as soon as possible to prevent further failure.

racks

A set of components cabled together to communicate between themselves. A rack is a container for an enclosure.

Simple Network Management Protocol (SNMP)

One of the management protocols supported by HP Systems Insight Manager. Traditional management protocol used extensively by networking systems and most servers. MIB-2 is the standard information available consistently across all vendors.

system

Nodes on the network that communicate through TCP/IP or IPX. To manage a system, some type of management protocol (for example, SNMP, DMI, or WBEM) must be present on the system. Examples of systems include servers, workstations, desktops, portables, routers, switches, hubs, and gateways.

uncleared event status

Events that have a Critical, Major, Minor, Normal, or Informational severity.

  • Critical. A failure has occurred, and immediate attention is required.

  • Major. A failure is impending.

  • Minor. A warning condition exists that can escalate into a more serious problem.

  • Normal. These events are not a problem.

  • Informational. No attention require. This status is provided as useful information

unknown status

HP Systems Insight Manager is not able to obtain management information about the system using SNMP or DMI. Although no management instrumentation information is available, the system can be pinged. It might have an invalid community string or security setting.

user

A network user with a valid login on the CMS that has been added to HP Systems Insight Manager.

Version Control Agent (VCA)

An agent that is installed on a server to enable you to see the HP software installed on that server. The Version Control Agent can be configured to point to a Version Control Repository Manager agent, enabling easy version comparison and software update from the repository.
