If enabled, the system will historize the average number of milliseconds between checkpoints for the averaging period. |
None |
|
Historize execution time average |
Scheduler.ExecutionTimeAvg.Historized |
If enabled, the system will historize the average number of milliseconds required to execute all objects per cycle. |
None |
|
Historize housekeeping time average |
Scheduler.HousekeepingTimeAvg.Historized |
If enabled, the system will historize the average number of milliseconds required for this object to do housekeeping tasks per cycle. |
None |
|
Historize time idle average |
Scheduler.TimeIdleAvg.Historized |
If enabled, the system will historize the average number of milliseconds per scan period that the object is idle (for example, receiving data, or sending data). |
None |
|
Historize input message size average |
Scheduler.InputMsgSizeAvg.Historized |
If enabled, the system will historize the average size of an input message, in bytes, for this averaging period. |
None |
|
Historize input messages processed average |
Scheduler.InputMsgsProcessedAvg.Historized |
If enabled, the system will historize the average number of input messages, in total bytes, in the input queue per scan period (including deferred and processed messages). |
None |
|
Historize input messages queued average |
Scheduler.InputMsgsQueuedAvg.Historized |
If enabled, the system will historize the average number of messages queued, including processed and deferred messages, per scan period. The value is calculated for the averaging period. |
None |
|
Historize input queue size average |
Scheduler.InputQueueSizeAvg.Historized |
If enabled, the system will historize the average size, in bytes, of the input queue during the averaging period. |
None |
|
Historize time input average |
Scheduler.TimeInputAvg.Historized |
If enabled, the system will historize the average number of milliseconds required to process input messages per scan period. |
None |
|
Historize time output average |
Scheduler.TimeOutputAvg.Historized |
If enabled, the system will historize the average number of milliseconds required to process output messages per scan period. |
None |
|
Historize scan overrun count |
Scheduler.ScanOverrunsCnt.Historized |
If enabled, the system will historize the number of scan overruns since the last time statistics were reset. |
None |
|
Historize R/W Interrupts time average |
Scheduler.ExecInterruptsTimeAvg.Historized |
If enabled, the system will historize the average number of milliseconds required to perform execution interrupts per engine scan cycle. |
None |
