One way OIT Networking & Monitoring Services monitors the campus data nework is by collecting statistics. Many of the statistics measure traffic volume flowing through the network infrastructure. In some cases, we collect other relevant data; for example, CPU usage of key infrastructural components. We also collect some statistics provided by a few hosts attached to the network.

Campus Core and Border Switches Traffic Statistics
These switches comprise the core (and Internet/Internet2 border) of the campus network. Some of these switches are the Layer 2 presences of switch/routers whose Layer 3 presences appear in the router document below.

Router Traffic Statistics
Traffic volume passing through OIT's core and Internet/Internet2 border routers. Also selected statistics for some departmental routers. Some of these routers are the Layer 3 presences of the switch/routers whose Layer 2 presences appear above.

Campus Aggregation Switch Traffic Statistics
Traffic volume passing through building aggregation switches and building point of entry switches.

Remote Access Traffic Statistics
These include selected Remote Access connections to the campus network, including OIT's VPN service and some DSL-attached sites.

Multiplexor Traffic Statistics
These include switches and chassis-based media converters associated with multiplexors.

Server Traffic Statistics
Ethernet switch ports located in the OIT Data Centers and OIT Network Core. This excludes ports attached to network infrastructure, firewalls, load balancers. This document primarily includes "servers."

Wireless Statistics
Includes selected statistics for the campus network's wireless infrastructure.

DHCP Dynamic Lease Statistics
Shows the number of DHCP leases assigned for dynamically-assigned IP addresses provided by OIT Mobile IP Service, Temporary Visitor Wireless Network Access (TVWNA), Temporary Unregistered Dormnet (TUD) IP Service, and Visitor IP (VIP) Service.

This tool will soon be retired .
