NORDstat features
This package has the following main features:
- The amount of work to maintain the setup is attempted to kept at
a minimum. This means "no per-port configuration work" apart
from setting up the port on the router.
- The package uses "logical port names", so that when a connection
moves from one router to another at the same PoP it can keep its
logical name.
- Information about line speeds and logical port names is pulled
from the routers, thus you need routines to keep this
information up to date.
- There are three main entry points to the statistics, a
clickable graphical map showing the circuit loading with
colour codes,
zoomable plots for the individual ports, and an entry point to tabular
reports covering various time periods. (The references here
lead to "live" examples of these features.)
- Implemented using freely available tools; uses TCL, Scotty, perl
(version 5), gnuplot (beta version), GD library etc. See
the list of tools for a complete list
and pointers to the tools used to implement this package.
- CGI script results written to be cacheable, and in most cases
sensible HTTP Expires headers are emitted to control cache
expiration of documents returned.
- Most scripts emit sensible ALT= tags so that it is possible to
use lynx to look at the statistics.
