GLORIAD Utilization Monitoring System (GMON)

The new GMON system ( http://www.gloriad.org/gloriad/monitor/), launched January 8, 2001, represents a complete re-write of the original system, adding many additional analyses, a new "graphic" method of exploring network usage, faster creation of charts and tables, and incorporating a much improved code base.

The following explains the improvements - primarily from a user's point of view - but with some additional technical information.

GRAPHIC INTERFACE

The system now generates CGI imagemaps for almost all charts and graphs produced - allowing the user to click on a "bar" of interest and resulting in a more detailed/refined analysis of the network usage data represented by that graph object. Thus, a user looking at a graph of monthly traffic from Russia to Asia can click on one of the "month" bars and will be taken to a more detailed analysis - showing a day-by-day usage summary, a further breakdown by network protocol, and a summary table showing the top institutional "partnerships" represented during that month. The new graphs are themselves "live" allowing the user to dig further into the data. Ultimately, the user can see a detailed summary of traffic between specific host machines for specific protocols of traffic.

Each new analysis provides a detailed listing of the query parameters used in generating the new chart or table.

NETWORK DOMAIN ANALYSIS

• To help the user explore network usage by network domain (i.e., kiae.ru, nasa.gov, etc.), the system can now track domains at three-levels (instead of the former two-level capability). In the case of NASA, for example, the system now differentiates usage at the Goddard Space Flight Center from that at the Jet Propulsion Lab.

• On the domains report (and for all other analyses), the system provides an additional optional search parameter of network protocol. Thus, for example, one can now look at FTP usage vs. Web usage vs. UDP-Other usage, etc. The parameter is provided on all search screens.

• The domains report screen (and almost all other analysis screens) now provides source country and destination country as optional query parameters. Thus, one can look at heaviest institutional network users between, for example, Russia and the US or Russia and Japan, etc.

COUNTRY ANALYSIS

1. A month-to-month total chart

2. A pie chart showing breakdown of traffic by protocol;

3. A pie chart showing breakdown by top institutional domains in Russia receiving traffic from US domains;

4. A month-to-month bar chart of top institutional domains in Russia receiving traffic from US domains;

5. A similar bar chart to (4) but showing how percentage of traffic to domains in Russia has changed on a monthly basis;

6. A month-to-month bar chart of top US domains *providing* data to Russia;

7. A similar chart to (6) but showing percentage changes per month

8. A month-to-month bar chart showing total traffic per protocol

9. A similar chart to (8) but showing percentage changes per month.

   All of the bar charts are "live" - allowing the user to go deeper into the analysis for a day-to-day look at traffic, more detailed information on network domains (and who they are sending or receiving data to/from), etc.
