Selecting Statistics to Collect
You can enable or disable individual core data collections on each available data source. The following core
collections are available on the ALL SPAN, DATA PORTS, and VLAN data sources:
• Application Statistics--Enables the monitoring of application protocols observed on the data source.
• Host Statistics (Network and Application layers)--Enables the monitoring of network-layer host activity.
• Host Statistics (MAC layer)--Enables the monitoring of MAC-layer hosts activity. Also enables
monitoring of broadcast and multicast counts for host detail screens.
• Conversation Statistics (Network and Application layers)--Enables the monitoring of pairs of network-
layer hosts that are exchanging packets.
• Conversation Statistics (MAC layer)--Enables the monitoring of pairs of MAC-layer hosts that are
exchanging packets.
• VLAN Traffic Statistics--Enables the monitoring of traffic distribution on different VLANs for the data
source.
• VLAN Priority (CoS (Class of Service)) Statistics--Enables the monitoring of traffic distribution using
different values of the 802.1p priority field.
• Network-to-MAC Address Correlation--Enables the monitoring of MAC-level statistics, which are
shown in host detail windows. Without this collection, a MAC station cannot be associated with a
particular network host.
