About polling

Network polling determines whether a network device is up or down, whether it has exceeded key performance parameters, and identifies inter-device link faults. If a poll fails, Network Manager generates a device alert, which operators can view in the Event Viewer.

Network Manager polling policies poll network devices at regular intervals, and if something does not match the polling criteria, an event is generated. For example, a polling policy might retrieve the CPU utilization of a device at a periodic interval. If the CPU utilization exceeds a predefined threshold, then an event is generated.
