DCE alarm configuration

  Use the options in the Alarm Configuration persective to configure how the server reports alarms and threshold violations and manages alarm actions for monitored SNMP and Modbus devices.   By default, four views appear in the Alarm Configuration perspective. These views, and the Manage Alarm Actions menu option, allow you to perform threshold and device alarm configuration and notification functions for monitored SNMP and Modbus devices.   Navigation view: contains the navigation tree, listing device groups and the monitored devices associated with them. This view allows you to do the following: Select a device group or device in the navigation tree to view the list of thresholds or device alarms that can be configured or added to a notification policy. Select a device group or device in the navigation tree and create thresholds for that selection. Edit thresholds. View device sensors and current sensor data for the selected device. Enter and exit maintenance mode to prevent and re-enable alarm notifications for the device groups or devices selected. Add and remove thresholds from a notification policy. Select a device group or device in the navigation tree and edit the configuration for all the device alarms for the selection. Select a device group or device in the navigation tree and change the notification policy associated with that device group or device. Note A device can be associated with only one notification policy at a time. Modify the default labels in the navigation tree.   Notification Policies view: displays the default notification policy, user-created notification policies, and the notification policy details. This view allows you to do the following: Create, modify, and delete notification policies. Double-click a notification policy to view the actions, thresholds, and devices associated with it. Note: The Default notification policy can be edited and renamed, but it cannot be deleted. At device discovery, alarms for SNMP and Modbus devices monitored by the Data Center Expert server are added to the Default notification policy. You can change the notification policy associated with a device from Change Device Alarm Notification Policy, a right-click option in the Navigation view.   Threshold Alarm Configuration view: displays the list of thresholds that can be configured or added to a notification policy. By default, a communication link status threshold is displayed for every device monitored by the Data Center Expert server. This view allows you to do the following: Modify and delete thresholds. Note: You cannot delete communication link status thresholds. Add and remove thresholds from notification policies. Display the notification policies associated with the selected thresholds. Find the device associated with the selected threshold in the Navigation view.   Device Alarm Configuration view: displays the list of device alarms that can be configured or added to a notification policy. This view allows you to do the following: Enable or disable an alarm, modify the severity and recommended action, and add a custom description. Find the device associated with the selected alarm in the Navigation view. Expand the list when there is more than one device alarm in the selection.  

Set thresholds for numeric sensors that monitor values not covered by the nine threshold-specific numeric options. The following lists identify some common examples of numeric sensors you can configure using the Other Numeric Sensors option. The actual sensors will depend on the device types managed by the Data Center Expert server. Note: You can configure multiple sensors discovered for the Other Numeric Sensors option, when the sensors you select can all use the same threshold settings. For example, battery and UPS age sensors, can be configured to use the same thresholds, as can utility, input, and output voltage sensors. UPS Battery Sensors: Battery Age Battery Runtime Remaining Battery Capacity Remaining Time Running on Battery Other UPS Sensors: UPS Age Input Frequency Output Frequency Output Load Output Power Percent VA Other Sensors: Max Number of Output Relays Max Number of Input Contacts Runhours of Fan Air Flowrate of Fan (in cfm) Total Air Flow (in cfm) RPM Speed of Fan

    Numeric alert thresholds Numeric alert thresholds are thresholds defined for sensors that report numeric values. There are nine specific types of numeric thresholds that can be set on numeric sensors. Numerical threshold options All alert threshold options, except Power (VA) and Power (Watts), can be used to set threshold settings at a NetBotz Appliance for itself, its sensor and camera pods, and other devices it manages. The Other Numerical Sensors and Other State Settings options, and for some third-party devices, Voltage, can be used to set threshold settings at a NetBotz device for the full SNMP support devices it monitors. Value<n> ft/minRelative number (0 - 100)Amps (0.0 - 100.0)°F (-40.0 - 122.0)/°C (4.5 - 50.0)% (0 - 95)VariedVAW°F (-40.0 - 122.0)/°C (4.5 - 50.0)V Threshold Description Air Flow Settings for sensors that measure air movement as feet per minute. Note Sensors that use a different measurement, such as cubic feet per minute (CFM) will be displayed under the Other Numeric Sensors option. Audio Settings for sensors that measure the volume of sound. Current (Amps) Settings for sensors that measure current as total amperage (amps). Dew Point Settings for sensors that measure dew point as degrees Fahrenheit (°F) or Celsius (°C). Humidity Settings for sensors that measure relative humidity as a percentage (%). Other Numeric Settings Settings for sensors that measure numeric settings not reported for other Alert Thresholds options. Power (VA) Settings for sensors that measure power as total Volt-amperes (VA). Note Sensors that measure power as a percentage of VA will be displayed under the Other Numeric Sensors option. Power (Watts) Settings for sensors that measure power as total watts (W). Temperature Settings for sensors that measure temperature as degrees Fahrenheit (°F) or Celsius (°C). Voltage Settings for sensors that measure either AC or DC voltage as total volts (V). Numerical threshold types Setting Description Minimum Value Threshold An alarm occurs when the sensor's value is below the Minimum setting. Maximum Value Threshold An alarm occurs when the sensor's value is above the Maximum setting. Range Threshold An alarm occurs when the sensor's value is outside the range defined by the Minimum and Maximum settings. Below Value for Time Threshold An alarm occurs if the sensor's value is below the Minimum setting for longer than the Time Allowed Below Minimum setting's delay. Above Value for Time Threshold An alarm occurs if the sensor's value is above the Maximum setting for longer than the Time Allowed Above Maximum setting's delay. Rate of Increase Threshold An alarm occurs if the sensor value increases by more than the Maximum Increase setting since the last time the sensor's value was sampled. For example, at a sensor that measures amps, 1 would result in an alarm when the amps measured by the sensor increases by one amp. Rate of Decrease Threshold An alarm occurs if the sensor value decreases by more than the Maximum Decrease setting since the last time the sensor's value was sampled. For example, at a sensor that measures total watts (W), 100 would result in an alarm when the watts measured by that sensor goes down 100 watts.  

    Managing a remote user Use the "User Configuration" display to edit the user role assigned to a remote user. Note To add a remote user, use the Authentication Servers tab; to delete a remote user, select that user in the Users and User Group Details section of the Users tab and click Delete. In the Users and User Group Details section of the Users tab, select a listed remote user and click Edit, to access the "User Configuration" display. Note For a remote user, only the User Roles selections in the User Information tab are available. In the User Roles section, select a role for the user, if any, and click Apply. Note The Data Center Expert Administrator role provides full access to all server, monitoring, and surveillance functions.  

    Creating alarm notifications Use the Alarm Configuration perspective to define the alarm notifications you want available to the server for monitored SNMP and Modbus devices. You must do the following before the Data Center Expert server can generate alarm notifications: Create at least one alarm action. Add at least one alarm action to the Default notification policy. You can do the following to specify how the Data Center Expert server generates additional alarm notifications: Create thresholds for sensor types supported by each device. Create new notification policies. Add at least one alarm action to each notification policy you created. Add thresholds, devices, and additional alarm actions, to the Default notification policy, or notification policies you created. Add SNMP and Modbus devices to notification policies you created. Modify thresholds or device alarm configurations, if necessary. You can create and configure thresholds, alarm actions, and notification policies, or modify device alarm configurations, at any time, in any order. For example, you can create alarm actions first, create thresholds, then add selected actions, thresholds, and devices, as needed, to the Default notification policy. Alternatively, you can create new notification policies first, then create actions or thresholds, and add them to any notification policy.  

    "Search" field Use the Search field to filter the list based on text you type. You can broaden or narrow your search using the Boolean operators AND, OR and NOT. For example, you can search for UPS AND On Battery; PDU NOT Phase 1; Humidity OR Temperature; Humidity OR Temperature NOT UPS. Only items that contain the text you specify in the Search field are displayed. When the results of a search are displayed, the background of the search field is shaded. When you clear the search field, the background shading is removed and all items are displayed. Note Search fields support the Boolean operators AND, OR, and NOT only.
