Lost events
Because the controller is a fixed capacity resource, under extreme conditions, it is
possible for event data to be lost. Event data can be lost when:
- A step is run and then the step is run again so soon after the first run that the step’s event buffers are overwritten.
- The event log within the controller overwrites event data that has not yet been published. This can happen because the <SEQMGR> Event Client Service is not subscribed for too great a time, or the sustained number of events generated exceeds the rate events can be published.
In both cases a
Lost Event
record is written to the .EVT file and the event
database (if configured) to signal that at least one event has become lost. Provide Feedback
