knxnetIp-KnxPollScheduler

The network Poll Scheduler maintains a group of four rate buckets to service pollables, three of which correspond to configured poll rates (slow, normal and fast) and one (dibs stack) which is allocated for pollables that transition to a subscribed state.

To access these properties, expand Config > Drivers in the station Nav tree, right-click the KnxNetwork node, click Views > AX Property Sheet, and expand Poll Scheduler properties.

Property Value Description
Poll Enabled true (default) or false Enables and disables the Poll Scheduler.
Fast Rate hh-mm-ss, 1ms ... +inf Defaults to 00–00–01 Configures the interval that defines this polling rate. The interval applies to devices, which the driver can poll.
Normal Rate hh-mm-ss, 1ms ... +inf Defaults to 00–00–05 Configures the interval that defines this polling rate. The interval applies to devices, which the driver can poll.
Slow Rate hh-mm-ss, 1ms ... +inf Defaults to 00–00–30 Configures the interval that defines this polling rate. The interval applies to devices, which the driver can poll.
Statistics Start read-only date time Reports either the last manual reset of poll statistics or, if statistics have not been reset, the first steady state time immediately following the last station restart.
Average Poll read-only time Reports the average time spent during each poll event. This does not relate to the total time required to complete a poll cycle for any of the three rates. It is the time spent polling a given group of objects before pausing and switching to another group either using the same or a different poll rate.
Busy Time read-only time Displays a percentage of time spent by the poll thread actually polling points using all poll rates. Includes (in parentheses) the ratio of time spent polling/total time since statistics were restarted.

Given a small amount of time is spent transitioning among poll rates, and with the thread sleeping to evenly space out polling messages, it is unlikely to ever see Busy Time reach exactly 100%. However, any percentage above 95% indicates that the poll thread is basically spending all of its time actually polling.

 
NOTE: In the case of the Poll Service for a BACnet network port, because two threads are used for polling, it is possible to see a Busy Time approaching 200%. In this case, divide Busy Time in half to get an average busy time for each thread.
 
Total Polls read-only Numeric over time Reports the total number of polls conducted and the time spent waiting for polls to execute. This time is the same time indicated in the ratio of the Busy Time property. Typically, the total poll count indicates the number of times the PollService polled any object. It is not a running total of the actual poll cycles.
Dibs Polls read-only Numeric % (Numeric/Numeric) Reports the percentage and ratio of the number of DIBS polls versus total polls.
Fast Polls read-only Numeric % (Numeric/Numeric) Reports the number of polls made processing the fast queue.
Normal Polls read-only Numeric % (Numeric/Numeric) Reports the number of polls made processing the normal queue.
Slow Polls read-only Numeric % (Numeric/Numeric) Reports the number of polls made processing the slow queue.
Dibs Count read-only current=numeric average=numeric Reports the current and average number of components in the DIBS stack. (DIBS stands for Distributed Internet Backup System).
Fast Count read-only current=numeric average=numeric Reports the current and average number of components in the fast queue.
Normal Count read-only current=numeric average=numeric Reports the current and average number of components in the normal queue.
Slow Count read-only current=numeric average=numeric Reports the current and average number of components in the slow queue.
Fast Cycle Time read-only average = time Reports the average cycle time for the fast queue.
Normal Cycle Time read-only average = time Reports the average cycle time for the normal queue.
Slow Cycle Time read-only average = time Reports the average cycle time for the slow queue.
