Alarms displayed in the alarm views

The alarms listed in the alarm views (Active Alarms view or Alarm History view) depend on whether a device or set of devices are selected in the Device View or Map View, and, for some devices, whether a threshold related to an alarm has been defined at the server.

• When a device or set of devices is selected in the Device View or Map View, only the alarms associated with that device or set of devices are listed in an alarms view.
• When an alarm threshold has been defined at the Data Center Expert server for a sensor at a monitored device, two alarms may be listed in an alarms view for the same sensor event:
  • An alarm sent to the Data Center Expert server by a monitored device.

  • An alarm generated by the Data Center Expert server when the data it monitors for that device sensor violates the alarm threshold setting defined at the server for that sensor.

Not all SNMP devices can send alarms to the Data Center Expert server. Also, the thresholds at SNMP devices are independent from the alarm threshold settings at the Data Center Expert server.
