CAUTION:
Have no more than 20,000 targets on a single monitor. Your system may not keep up with polling if you
exceed the recommended target limit. Best practice is to poll important devices in shorter intervals and
less important devices over longer intervals.
NOTE:
You can elect to monitor the same attribute in multiple, different monitors. This has a performance
impact. Best practice is to monitor an attribute only once.
