Glossary Of Terms

Terms and definitions used by REM.

Sender

A software module that converts Events into messages formatted for external systems, such as SMS, Email or NMS systems.See also: Listener, SMTP, Zone

Sensor (Device)

Usually an electrical or electronic device which measures a quantity, and generates an output value that can be related to the quantity measured. Some sensors may in fact be ‘virtual’, where a reading is calculated from other sensor readings (for example many dew point or air flow sensors).See also: Device, Gross Type, Sensor Node

Sensor Node

A chargeable element of the REM Enterprise Server licence agreement. Each sensor node is a device capable of communicating to REM via IP networking. For example, an AxxessID iBox, APC Netbotz 500 and Sinetica Hawk-i2 are all sensor nodes.See also: Interface (Device), Sensor (Device)

Severity

REM ES allows events of different kinds, such as temperature Alarms or a sensor ceasing to report, to be assigned a severity. They range between 0 (Clear) and 5 (Critical). Alarm Point Profiles assign the severities for a sensor reading which exceeds the configured thresholds. Others are fixed within REM ES. They determine the colour of an event on the Event View and are passed on in any messages emitted by REM ES to an NMS or other recipient.See also: Alarm Point Profile, Event View

SMTP

Simple Mail Transport Protocol, or “How E-mail is sent”.See also: Sender

SNMP

Simple Network Management Protocol. A standard networking Protocol, which passes data, alarms and configuration between systems.
