Overview

OIT monitors traffic volume on OIT Ethernet switch ports in the OIT Network Core at 87 Prospect Avenue, and the OIT data centers at New South and the HPCRC.

This document includes the switch ports in those locations, excluding those ports attached to devices which are part of the network infrastructure. We also exclude ports attached to devices which are firewalls, load balancers with multiple logical or physical interfaces, OIT Remote Access Servers, and part of the OIT Wireless infrastructure. The switch ports attached to devices are included on other documents; see OIT Network Systems: Statistics.

We normally collect traffic data from the network infrastructure (e.g. an Ethernet switch) to which the device is attached, as opposed to collecting traffic data directly from a host. As a result, the traffic graphed as "incoming" (in GREEN) represents traffic entering the network port from the host, while the traffic graphed as "outgoing" (in BLUE) represents traffic leaving the network port to to the host.

For each monitored target, you may view graphs showing the traffic volume in and out of the corresponding network interface over several recent time periods (the past 31 hours, 8 days, 31 days, and 365 days). In most cases, volume is measured by bit rate and packet rate.

The monitoring is performed with mrtg, rrdtool, and mrtg-rrd.

Except where noted otherwise, links listed below are attached to VLAN 128 (princeton-net).

In a few cases, we also monitor other statistics provided by the server (in addition to, or instead of, information provided by the Ethernet switch port).

The display you see will be refreshed automatically by your Web browser every five minutes.

As many of the devices below are OIT devices or are managed by OIT, they have been grouped roughly by the service they provide. Non-OIT devices are usually grouped by the department associated with the device. The remainder appear in a Miscellaneous and Uncategorized Services group at the end.

If you adminster a device that is missing from this page, and the device is attached to an OIT Ethernet switch port in OIT Network Core at 87 Prospect Avenue, or the OIT data centers at New South and the HPCRC. please contact OIT Network Systems (by placing a ticket in the OPM NET-INCOMING queue), to have the device added to this page. (Turnaround time for such updates is typically over a month.) Before doing so, first be sure that the device is accurately registered in the Host Database; incorrectly registered hardware addresses are often the reason devices do not appear in this page.

If you administer one of the devices below and believe it is listed in the wrong group, or that the name is no longer correct (we use canonical Host Database names based upon the device's hardware address), contact OIT Network Systems (by placing a ticket in the OPM NET-INCOMING queue). This page is manually maintained, so adds, moves, deletions, and changes to devices may not be reflected here until you advise us. (Turnaround time for such change requests is typically over a month.) Be advised that we rely on each device's hardware address to determine the name that appears below and on the graphs; it is important that the hardware address be accurately registered in the Host Datbase to avoid mis-labelled information below.

The OIT ESS Systems group also collects performance data from all UNIX servers they maintain; see OIT System Performance (access is restricted).
