7.4.5 Adaptive Polling
VNEs implement adaptive polling ensuring that the element is not overloaded
in addition to defined polling intervals. Checking the device CPU usage, may
defer specific polls in order to avoid an additional load on the managed
element.
When a VNE exceeds the maximum CPU usage threshold value an alarm is
sent and the VNE is automatically transferred to a slow polling interval,
namely, the VNE is polled less regularly.
When the CPU usage threshold values for the VNE fall below the clear
threshold value then an alarm is sent and the VNE returns to normal polling.
The values for any VNE can be customized through the system registry, for
example, the minimum and maximum CPU usage threshold values. When the
defined values are reached an alarm is sent. A clear value can also be defined
so that when the CPU usage threshold value drops below the maximum value
or rises above the minimum value a message is sent clearing the original
alarm. These values are defined in the Registry.
