Reducing StatisticalInterface
The StatisticalInterface table stores data collected by the Interface Utilization performance
monitor when enabled on a device.
There are several options to reduce the size of this table, listed in order of least impact to the
monitoring system.
1 Enable monitoring only for the important interfaces in your network.
By default, WhatsUp Gold monitors all the active interfaces on every device that
supports SNMP and has interfaces. An active interface is defined as an interface which is
both enabled and has a link. This can include Windows workstations, connected but
unused ports on switches, and other devices. You should collect interface utilization
information from only those interfaces for which bandwidth availability is a concern.
You can set WhatsUp Gold to poll only the specific interfaces you identify by configuring
the Interface Utilization performance monitor on the device to only poll Specific
interfaces. You can do this from the Device Properties - Performance Monitors (on page
121) dialog. Also, consider only monitoring interface utilization for one side of a
connection. For example, if Port1 on SwitchA is connected to Port2 on SwitchB,
monitoring interface utilization on both ports displays the same information, just in
opposite directions. Monitoring interface utilization on both ports is redundant.
You should also consider disabling data collection on workstations and servers whose
interface speeds are greater than the switches to which they are connected. For
example, a desktop workstation with a Gigabit interface that is connected to a 100Mbps
switch will never reach capacity at the workstation side of the connection. Instead,
monitor for interface utilization on the switch. For more information, see the Configure
Interface Data Collection (on page 822) dialog help.
2 Increase the polling interval for the Interface Utilization performance monitor on noncritical
devices.
By changing how often WhatsUp Gold collects data from devices, you can decrease the
amount of storage needed in the database for the monitor's records. This can be done
on a per-device basis from within the Device Properties - Performance Monitors (on page
121) dialog or for all devices using the Bulk Field Change feature. We recommend
setting each device manually as this allows for separate intervals and will not change the
collection type for the monitor on the device. For more information, see Configuring the
Interface Utilization Monitor collection settings (on page 256) and the Bulk Field Change -
Performance Monitor (on page 820) dialog help.
