• Even if the object for which a MIB variable is monitored is not
running a VPO intelligent agent, the threshold monitor can still
reduce the network load. In this case, it is recommended to use an
intelligent agent running on a machine located close to the
monitored object. Additional network load caused by MIB variable
polling is, therefore, restricted to a small part of the network. This
reduces the overall network load and the workload of the
management server. If the VPO management server is connected
to the managed objects over a WAN, this situation can be
especially beneficial in terms of network load.
