Enabling Core Monitoring
In the Core Monitoring menu, you are presented with all the monitoring and reporting options available to identify most
of the network, application, and VLAN reports that are provided by RMON and SMON MIBs. To configure the NAM to
collect and monitor any of these options for a given data source, first select the data source from the pull-down menu
and then simply check the box to the left of the desired monitoring option. Core Monitoring options include:
Application statistics: This option enables monitoring and reporting by application protocol. This is useful for
identifying which protocols are consuming the most bandwidth and enables proactive planning based on application
usage patterns.
Host statistics (network and application layers): This option enables host monitoring and reporting by network
address. This information is useful for identifying which stations, servers, and end users are generating the most traffic
by network and application protocol.
Host statistics (MAC layer): This option enables host monitoring at the MAC layer, Layer 2. Not available for NM-NAM
and NDE data sources.
Conversation statistics (network and application layer): This option provides monitoring by network layer host pairs.
This is very useful to identify utilization patterns between clients and servers and can also be used to identify
configuration errors for network devices and identify broadcast and multicast traffic by network address.
Conversation statistics (MAC layer): This option provides monitoring by MAC layer host pairs. This can often be
useful in identifying configuration errors for networked devices, and it identifies broadcast and multicast traffic by MAC
address. Not available for NM-NAM and NDE data sources.
VLAN traffic statistics: This option enables monitoring and reporting distribution by VLANs. This is useful for
identifying resource usage patterns by VLANs. Available only for ALLSPAN and DATAPORT aggregation data sources.
Not available for NM-NAM and NDE data sources.
VLAN priority: This option enables monitoring VLANs by the values set in the 802.1p priority fields. This can be used
to validate class-of-service (CoS) configuration. Not available for NM-NAM and NDE data sources.
Network-to-MAC address correlation: This option enables monitoring MAC-layer statistics that populate the host
detail views. This also provides network address-to-MAC address correlation. If you turn this off, the NAM will not
associate MAC address with network layer host information. Not available for NM-NAM and NDE data sources.
