Load
Memory Usage
Reported for hubs and RMON2 probe protocols
Description hub: load of a hub
probe: load of a protocol on a LAN link
Units percentage of CPU load
Default
thresholds
■ hub: minimum 20%–maximum 60%
All the devices connected to the hub are affected during high loads, which
damage the network.
■ probe: Thresholds will be set only if the interface’s line flow rate has been
correctly captured or entered.
■ LAN interfaces: minimum 30%–maximum 40%
Points to check hub: none
probe: Use the Compare function to identify the type of protocol that saturates the
network or makes the greatest use of the network.
Reported for Cisco, BayNetworks Access Node, Motorola, ACC, and Fore Systems devices
Description memory usage of the currently monitored device
Units percentage of memory used
Default
thresholds
minimum 20%–maximum 40%
Points to check raise upper limit to avoid a reduction of the traffic flow
