Ipswitch WhatsUp Gold User Guide
By adding an up dependency on each host so that the polling of the hosts is dependent on
the Ping monitor on Switch N being up, denoted Up Dependency: Switch N (Ping Monitor),
you create the condition where WhatsUp Gold discontinues polling the hosts when Switch N
is powered down or otherwise unavailable to the Ping(Switch N) monitor. This reduces the
overhead required to monitor the dependent host devices, while providing information
about their accessibility based on the accessibility of Switch N.
Down Dependencies
A down dependency establishes a rule so that a device is polled only if the selected active
monitors on a second device are in the down state. The device can be thought of as
something is “in front of” the device to which it has a dependency. The dependant devices in
front will not be polled unless the device further down the line is down.
