DCE alarm thresholds

    Creating numeric and state thresholds All numeric and state thresholds use the same basic procedure and displays to create threshold settings. Note The same displays are used to create thresholds when you select the Create Thresholds option in any of the following: The Alarm Configuration menu. The right-click menu in the navigation tree in the Navigation view of the Alarm Configuration perspective. The right-click menu in the Device Groups, Device View, or Map View of the Monitoring perspective. Threshold settings for all monitored devices are available when you use the Alarm Configuration menu options. Threshold settings for only the device group or device selected are available when you use the right-click menu in the Navigation view, Device Groups, Device View, or Map View. Select the sensor type on which you want to add a threshold from the Create Thresholds option in the Alarm Configuration menu. Alternatively, select a device group or device in the Alarm Configuration or Monitoring perspective views, and right-click to select the Create Thresholds option. In the "Select Threshold Type" display, select the threshold type you want to add, and click Next. In the "Select Sensors" display, select the sensor or sensors for which you want to add thresholds, and click Next. In the "Create Threshold" display, define the settings, and, if desired, configure when the server will generate notifications if the threshold becomes active using the Threshold Scheduling button, and click Next. In the "Select Notification Policies" display, select the notification policies to which you want to add the alarm threshold, and click Finish to exit the wizard.  

    Other numeric thresholds The Other Numeric Sensors option allows you to 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 use the same units of measure, and can be configured at the same time, 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  

    Thresholds and supported devices Which thresholds can be used for sensors at the monitored devices depends on the type of device. For a full SNMP support device or Modbus device monitored by the Data Center Expert server, all threshold options except Dew Point can be used to define threshold settings the Data Center Expert server will monitor for that device. These thresholds are created using the Create Thresholds option. Full SNMP support and Modbus devices When you create thresholds for full SNMP support and Modbus devices, the threshold settings you define are set at the Data Center Expert server, and used to monitor the associated sensors at those devices. Note  This can result in two alarms when a threshold you define at the Data Center Expert server is violated: one from the SNMP device, and one for the threshold violation at the Data Center Expert server. You can define thresholds for SNMP and Modbus devices to do the following: Set the threshold settings that the Data Center Expert server will monitor for these devices. Select the notification policies the Data Center Expert server will use for alarm notifications related to these devices. NetBotz Appliances When you create alert thresholds for a NetBotz Appliance, its sensor pods, camera pods, and monitored SNMP devices (using Alert Settings, a NetBotz Appliance Configuration option in the Device menu), the threshold settings are set at the NetBotz Appliance. It is the NetBotz appliance that stores the settings and sends the alerts to the Data Center Expert server. Note Because NetBotz Appliance alert profiles are device-specific, you will not be able to configure the profile for a threshold setting when configuring that setting for multiple appliances. Basic and model ID SNMP support devices For devices without full SNMP support, you can define supplemental OIDs for numeric sensors at those devices using Supplemental OIDs, an SNMP Device Communication Settings option in the Device menu. Once the supplemental OIDs are defined, you can create thresholds on the sensors.  

    Numeric alarm thresholds Numeric alarm 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 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. All threshold options except Dew Point can be used to define threshold settings the Data Center Expert server will use to monitor its full SNMP support devices. Value: <n> ft/min Relative number (0 - 100) Amps (0.0 - 100.0) °F (-40.0 - 122.0)/°C (-40.0 - 50.0) kWh% (0 - 95) VariedVA and kVAW and kW°F (-40.0 - 122.0)/°C (-40.0 - 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). Energy (kWh) Settings for sensors that measure energy consumption as kilowatt hours (kWh). 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 Thresholds options. Power (VA) Settings for sensors that measure power as total Volt-amperes (VA) or kiloVolt-amperes (kVA). 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) or kilowatts (kW). 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 value is below the Minimum setting for longer than the delay in the Time Allowed Below Minimum setting. Above Value for Time Threshold An alarm occurs if the sensor value is above the Maximum setting for longer than the delay in the Time Allowed Above Maximum setting. 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 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 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.  

State thresholds are thresholds defined for sensors that report state values. There are three specific types of state thresholds that can be set for state sensors. State threshold options Value: Open or Closed Unknown, No Fault, or Fault No Motion or Motion Detected Varied Threshold Description Door Settings for sensors that determine whether a door is open or closed. Dry Contact Settings for sensors that determine the fault status of dry contacts. Motion Sensor Settings for sensors that detect motion. Other State Sensors Settings for sensors that measure state settings not reported for other Thresholds options. State threshold types Setting Description State Threshold An alarm occurs when the sensor state matches the Alarm State setting. State Mismatch Threshold An alarm occurs when the sensor state does not match the Normal State setting. Note This threshold setting is useful for sensors that can report more than two states. State for Time Threshold An alarm occurs when the sensor state matches the Alarm State setting for longer than the delay in the Time Allowed in Alarm State setting. State Mismatch for Time Threshold An alarm occurs when the sensor state does not match the Normal State setting for longer than the time defined by the Time Allowed in Alarm State setting. Note This threshold setting is useful for sensors that can report more than two states.

    Create Thresholds option The allows you to create thresholds for any sensor reported by a device. In addition to the alarms available for each device, you can create thresholds for the Data Center Expert server. Two basic types of thresholds are available: those that use numeric settings, and those that use state settings. Note You can create a threshold for a virtual sensor using the Create Threshold option for the selected virtual sensor. You cannot create a virtual sensor for state sensors. See Virtual Sensors view for more information. Numeric thresholds: Air Flow Audio Current (Amps) Dew Point Energy (kWh) Humidity Other Numeric Sensors Power (VA) Power (kVA) Power (Watts) Power (Kilowatts) Temperature Voltage State thresholds: Door Dry Contact Motion Sensor Other State Sensors Both types of thresholds allow you to do the following: Create thresholds at one time for multiple sensors of the same type (for example, all are Humidity sensors, or all are Door sensors). Specify the severity and return-to-normal parameters for any defined threshold. Provide a custom URL and custom description for any defined threshold. Configure Threshold Scheduling to specify when any defined threshold is active. Add any defined threshold to one or more Data Center Expert notification policies. Five menus provide access to create alarm thresholds: Create Thresholds , an option in the Alarm Configuration menu. Right-click menu Create Thresholds in the navigation tree in the Navigation view. Right-click menu Create Thresholds in the Device Groups view in the Monitoring perspective. Right-click menu Create Thresholds in the Device View in the Monitoring perspective. Right-click menu Create Thresholds in the Map View in the Monitoring perspective. Each threshold option allows you to search the sensors monitored by the Data Center Expert server that match the selection. You can add a threshold to one of those sensors, or add thresholds with the same settings to any number of those sensors simultaneously. Using the right-click menus to add thresholds to one or more sensors allows you to focus threshold management to the sensors at a single device, or at a set of devices.

    Other state thresholds The Other State Sensors option allows you to set thresholds for state sensors that monitor operational states not covered by the three threshold-specific, state options. The following lists identify some common examples of state sensors you can configure using the Other State Sensors option. The actual sensors will depend on the device types managed by the Data Center Expert server. These options use the same set of four threshold settings as the other state threshold options. Note You can configure multiple sensors discovered for the Other State Sensors option, when the sensors you select use the same alarm states settings. For example, all sensors that use On and Off states can be configured at the same time, as can all sensors that use Up and Down.
