Collecting Performance Data Chapter 3
• Trigger
Defines how the event starts and ends (e.g., a bit in the control
system goes high to signal the start of the event and it goes low
at the end of the event).
For more information, see "Set the Event Trigger Parameters"
in the Configuration Console online help.
• Additional data
Optionally, an additional data point can be collected at the
start or end of the event, or a counter can be monitored
through the duration of an event. The additional data
collected may be the event reason code entered by the
operator, explaining why the event occurred.
For more information, see "Collect Additional Event
Information" in the Configuration Console online help.
• Event fault metrics
Not all events are relevant in the calculation of fault metrics.
Specify how the event should be used when calculating fault
metrics (Mean Time Between Failure, Mean Time To Repair).
Mean Time Between Failure and Mean Time to Repair are
derived fields that contain aggregate functions and, as such,
they can only be used in summary report objects, and you
cannot apply additional aggregate functions to them.
For more information, see "Set the Event Fault Metric And
Machine State Options" in the Configuration Console online
help.
• Event reporting properties
The reporting value property determines the type of value that
is reported for the event. The severity level property
determines the severity that is associated with the event. This
is useful for reporting and sorting events.
For more information, see "Set the Event Reporting
Properties" in the Configuration Console online help.
