One way OIT Network Switching and Routing 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.

Access is restricted to Web clients on Princeton University campus networks (excluding "visitor/external-like" networks), or Web clients which provide a valid Princeton University netid and password.

Campus Core and Internet Border Switches and Routers Traffic Statistics

These switches and routers comprise the cores and Internet borders of the campus network.

Campus Aggregation Switches and Routers Traffic Statistics

Traffic volume passing through Legacy Network building aggregation switches and building point of entry switches; and selected interfaces of Next Generation Network routers acting as primary routers in a multi-location complex.

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 Cores. This excludes ports attached to network core switches, as those appear instead in Campus Core and Internet Border Switches and Routers Traffic Statistics above.
