Network Monitoring Tools
OIT Network Switching and Routing uses a number of systems to monitor
the campus data network.
-
OMD
-
We monitor the reachability of campus network components with OMD (Open Monitoring Distribution).
Access is restricted to clients on the campus network;
attempting to access it from off-network will result in an error indicating the
host or server is not found, or cannot be reached.
Access is further restricted to selected accounts.

KB0012975: OMD - How to use Open Monitoring Distribution tool (Thruk)
.
-
Traceroute
-
Use this to trace the current path from www.net.princeton.edu
to another Internet host you specify.
-
Hardware Address Last in IP ARP Data (HALIAD)
-
The Hardware Address Last in IP ARP Data (HALIAD) facility
allows you to search recent IP ARP data collected by OIT.
You may search for a hardware address to learn the most-recent
date on which that address appeared.
Other Tools
-
DNS Lookup
-
A tool to lookup a hostname or IP address in the Internet's Domain Name System.
The tool is only available to on-campus clients.
-
Software for Network Administrators
-
A small collection of software developed or modified by
OIT Network Switching and Routing, of possible use to other network administrators.
