Glossary

Client

A PC connected to a device on the network.

Community String

The SNMP Community String is similar to a password, offering a limited amount of protection for the SNMP data.

HP Insight Management Agents

Software that can query a manageable device and provide information that responds to SNMP requests for data.

Corrected Memory Log

A log that contains a list of corrected memory errors.

Desktop Management

A feature of Insight Manager that allows you to monitor ProLiant PCs being used as clients.

In-band

Refers to a system's capacity to deliver information through existing network hardware. Synonymous with "on the network."

Logical Drive

In a Drive Array, multiple physical drives connected to the same controller are combined to create logical drives. All available physical drive capacity is used by the logical drive as if it were a larger drive subsystem. By combining several physical drives, special fault tolerance and performance features can be used.

Managed Device

A device managed by a management console. Devices include servers, workstations, routers, switches, and hubs. Servers and workstations cannot be managed devices unless HP Insight Management Agents are installed.

Management Information Base (MIB)

The document or file that defines all manageable traps known to the management agent and management application.

Management Console

The PC, workstation, or server running Insight Manager.

Monitored Item

The item Insight Manager manages or monitors, or the information that Insight Manager collects.

Network Interface Controller (NIC)

An adapter card installed in a PC, workstation, or server that allows the PC, workstation, or server to communicate with other devices connected to the same network. NIC usually implies a local area network (LAN) adapter card is installed.

Out-of-band

Refers to a system's capacity to deliver information through a modem. Synonymous with "off the network."

Physical Drive

In a Array Controller, multiple physical drives connected to the same controller are combined to create logical drives. The logical drive uses all available physical drive capacity as if it were a larger drive subsystem. By combining several physical drives, you can use special fault tolerance and performance features.

Point-to-Point protocol (PPP)

A standard defined by the Internet Engineering Task Force. PPP provides a standard method for transporting multiple protocols over a point-to-point link.

Simple Network Management Protocol (SNMP)

SNMP defines a set of commands that a management application uses to retrieve or change the values of items made available by a management agent.

Threshold

A limit you can set to produce an alarm if it is reached or exceeded.
