Which of the following is a historizable attribute for an engine?

A historizable attribute is one that can be tracked over time, allowing for the collection and analysis of historical data. In the context of an engine within the AVEVA Application Server, the attributes mentioned all serve different purposes and can provide valuable insights when historized.

The first attribute, which involves historizing issues internal gets count, allows for monitoring the frequency of internal requests or messages that the engine processes. By tracking this, users can identify patterns in engine performance or potential issues related to internal handling.

The second attribute pertains to historizing the received external gets count. This counts the external requests directed towards the engine, providing a clear view of how often the engine interacts with external components or systems. Historizing this data can help assess demand, response times, and the load the engine experiences from external interfaces.

The third attribute, the historize alarms throttled flag, tracks whether alarms are being limited or managed due to predefined criteria. This can reveal patterns of system behavior when alarms are generated, enabling users to manage system alerts more effectively.

Since all three attributes contribute to comprehensive insights regarding engine behavior, performance, and system management, they are all valid candidates for historization. Therefore, the selection of all the options as historizable attributes is accurate, as
