DCE alarm views

Provides information about the alarms that are active for all devices in a selected device group, or for any device or set of devices selected in the Device View or Map View.   Alarm acknowledgement display   Specify how you want to acknowledge selected active alarms at SNMP and Modbus devices.   Set as Hidden: Check to hide the alarm in the Active Alarms view of any Data Center Expert client logged in to the Data Center Expert server.   You can click the Show Hidden Alarms icon to view acknowledged alarms set as hidden. The information for affected alarms is italicized. You can then select any italicized alarms and uncheck the Set as Hidden option to display them in the view.   Suppress Future Data Center Expert Notifications: Check to prevent notifications from being sent for the alarm, when the alarm actions specified in the notification policy are set to repeat.   When the alarm is resolved, Return to Normal events are sent using the alarm actions specified in the notification policy.   Add comment: Enter additional information about acknowledging the alarm.

The Alarm History view provides information about the alarms that have occurred during a defined date range for the selected device groups or device(s). The alarms displayed can be active or resolved.   The title of the view identifies the selected devices or group. For example, Alarm History for All Devices, when the All Devices group in the Device Groups view was selected for the Alarm History view, or Alarm History for Selected Devices, when multiple devices in the Device View or Map View were selected for the Alarm History view.   You can access the Alarm History view in several ways: Alarm History, an Alarms option in the Window menu: lists alarms for the selected devices, whether that is all devices in the group selected in the Device Groups view, or the device or devices selected in the Device View or Map View. This Alarm History option performs this function only when the Alarm History view is not currently open. Once that view is open, this option has no affect on that view. Show Alarm History, a right-click Device Groups view option: lists the alarms for all devices in the group selected in the Device Groups view. Show Alarm History, a right-click Device View and Map View option: lists the alarms for the device or set of devices selected in the view.   Once the alarms for a device, set of devices, or device group are listed in the Alarm History view, they will remain listed in that view until you select a different device, set of devices, or device group and click the associated Show Alarm History option.   The Alarm History view includes a Search text field that allows you to list only those alarms that include text you type, a From Date and to date calendar control that allows you to define a new date range for the alarms, and a Search button you click to search for alarms associated with the new date range.   You can click the Configure columns icon to select the columns you want to see in the view. In DCE 8.2.0 and newer, a Comments column is available that displays the number of comments on each alarm.    The Alarm History view also includes information about the historical alarms for the selected devices. When you open this view, the date range is set for the last 24 hours by default.   A maximum of 500 alarm entries can be reported by a page, with additional pages provided for every additional 500 entries.

View Alarm Details and Comments is a right-click option in the Active Alarms view and Alarm History view. You can see Details for any active or historical alarm, and Comments, Clip and Graph data for that alarm, when available. The Clip option is available only for alarms that include a camera icon in the Clip column of an alarm list. The Graph option is available only for some of the alarms that list a sensor in the Sensor column of an alarms list, and unavailable for alarms that have no sensor identified in the Sensors column. Clip option Comments option Graph option Details option

In the "View Alarm Details" display, manually resolve alarms associated with sensor alert thresholds that have Return-to-Normal Requires User Input selected in the Advanced tab. Alarms that are not associated with a sensor threshold that has Return-to-Normal Requires User Input selected cannot be manually resolved. For more information about the Advanced tab, and other threshold settings, see Create Thresholds under Alarm Configuration. You can add Optional Comment text before you click OK to resolve the alarm.

View a graph for an alarm associated with a sensor. This is available only for some of the alarms that list a sensor in the Sensor column of an alarms list. It is unavailable for alarms that have no sensor identified in the Sensors column. Each graph has its value measurements labeled up the left side of the graph, and date and time values labeled across the bottom.

View information about a selected alarm. Three elements (Resolved by, Resolved Comment, and Resolve Alarm) are available only for an alarm that must be manually resolved because it is associated with a sensor alert threshold that has Return-to-Normal Requires User Input selected in its Advanced tab. Custom URL and Custom Description are from the Advanced tab for the alert threshold setting associated with the alarming sensor, when it is defined. For more information, see Alert Thresholds under Alert Settings (Device menu). The Recommended action contains information on how to clear the alarm, or use the Resolve Alarm display to manually resolve an alarm.

View, add, or remove comments about the selected alarm. You can add up to 25 comments for the selected alarm. The date and time the alarm occurred, and the username, date and time for each comment are displayed. You can click the X icon next to each comment to permanently remove it from the list. Events generated by the Data Center Expert server are italicized in blue. The date and time the alarm occurred, and the name of the user that acknowledged the alarm, if applicable, are displayed. System events cannot be removed from the list. Data Center Expert Server Administrator users can add and remove comments for any alarm. Device Administrator users can add comments for alarms at devices in the device groups to which they have access, and can remove only their own comments. Device Viewer users can view comments for alarms at devices in the device groups to which they have access. Note: For a non-Data Center Expert Administrator user, including a user for which no role is selected, access privileges are determined by Device Group Access settings in the Users tab for that user, and for the user groups to which the user is assigned.

View clips that were included with a selected alarm. A tab identifies each camera that has a clip attached to the alarm. The clip is displayed in the upper portion of the tab, while icons used to view each frame, and to export the clip, and information about the clip are provided in the lower portion. Element Description View Pane Shows the content of the clip.

Status area Displays the loading status of the selected clip: Loading or Loading Complete. Clip information Displays the following information about the current clip: Total Frame Count Duration Resolution

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.
