One way to access these properties, expand , right-click Alarms and double-click Poll Scheduler in the Nav tree.
| Property | Value | Description |
|---|---|---|
| Poll Enabled | true (default) or false |
Determines user control over polling.
|
| Fast Rate | hh-mm-ss, 1ms ... +inf Defaults to 00–00–01 |
Sets the target polling interval for devices that can be polled (they are pollable) and assigned to the Fast Rate group.
|
| Normal Rate | hh-mm-ss, 1ms ... +inf Defaults to 00–00–05 |
Sets the target polling interval for devices that can be polled (they are pollable) and assigned to the Normal Rate group.
|
| Slow Rate | hh-mm-ss, 1ms ... +inf Defaults to 00–00–30 |
Sets the target polling interval for devices that can be polled (they are pollable) and assigned to the Slow Rate group
|
| 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 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.
