Threshold values identify the rule component criteria of the polling attributes associated with a resource. These values typically identify the highest or lowest acceptable resource performance-related value for a specific resource. The type of threshold value varies according to the resource type. The OpenEdge Management System resource type threshold values are often characterized by the highest or lowest value definitions. The OpenEdge Management Network resource type threshold values relate to values defined for response times being greater than a specified value, or no response within a defined period of time.
During the monitoring process, when OpenEdge Management finds a value that is outside the defined threshold value, the rule is considered violated. This rule violation causes the alert to be generated and the action to trigger. See How OpenEdge Management alerts relate to rules and actions for more information.
Knowing how threshold values are interpreted can help you to interpret more accurately the context of a specific alert. For an explanation of these resource-specific calculations, see the appropriate resource-specific rule details in the system, network, or file resource rule calculations in OpenEdge Management: Resource Monitoring. For information about database rule details, see OpenEdge Management: Database Management. For details about OpenEdge server-related rules, see OpenEdge Management: Servers, DataServers, Messengers, and Adapters.
