settings
Settings are conditions of a manageable object help to determine what happens
when a certain value is detected in a component. For example, a user can set the
upper critical threshold of a temperature probe to 75 degrees Celsius. If the probe
reaches that temperature, the setting results in an alert being sent to the
management system so that user intervention can be taken. Some settings,
when reached, can trigger a system shutdown or other response that can prevent
damage to the system.
