Thresholds

By default, BPM Express for Hardware automatically sets alert thresholds on the parameters of monitored elements. Depending on the computer it is running on - BPM Express for Hardware sets different thresholds for the different parameters (temperature, voltage etc.).

How thresholds are set by BPM Express for Hardware

BPM Express for Hardware dynamically sets the thresholds on all of its parameters, depending on the platform it runs on. It receives the threshold values from the underlying instrumentation layer of the element. This is why a summary table of alert thresholds cannot be provided - they differ from system to system.

The alerts, i.e. the warnings and alarms are configured to be automatically raised via the Status parameter of each class. For example, a voltage instance has two parameters: Status and Voltage. When thresholds on the Voltage parameter are breached - by default the alert is displayed by the Status parameter icon, and not the Voltage parameter icon.

When default thresholds are modified, the alerts are displayed by the icon of the parameter whose thresholds have been modified. See Modifying Parameter Thresholds

Parameters configured to trigger alerts

It is only Status, the text parameter that shows the overall status of each monitored element and displays the alert conditions of warnings and alarms. For example, let's take the case of a network interface, which has the following instances under it:

●Link Status: Indicates whether or not the card is plugged
Values: Plugged = OK; Unplugged (if previously plugged in) = Alarm

●Error Percent: Displays the percentage of errors detected
Unit: %10-30 = Warning; 30-100 = Alarm

●Status: Displays the overall status of the instance
Values: OK; Unplugged = Warning; Critical/Missing = Alarm

If the network interface is unplugged, this information will be displayed by Link Status parameter icon in the History icon with all the details. However, only the Status icon will go into Warning. Similarly, if the Error Percent parameter thresholds breach alarm levels, it is the Status icon that will trigger and display the alarm and not the Error Percent icon.
