JKFlow provides the processing of netflow data into numerous RRDs which allows great breadth in the detail of the netflow data. This project focuses on developing an interactive and easy to use web based front ends to such data.
A current prototype of the netflow visualisation can be viewed at http://iepmbw.bnl.org/netflow/index.html.
To develop, test and document a flexible web based frontend for the netflow data. This will involve expanding and developing new code to improve the API and performance of the existing perl/cgi server side scripts and the client end javascripts.
The server side code is primarily a means to dynamically gather and present base components of the frontend; for example to display the statistics of from the BNL site to say SLAC. Much work needs to be conducted to expand the presentation consistency and to iron the bugs in the implementation.
Using the above prototype as a framework, learn and use AJAX technologies and methodologies to improve the user experience of the netflow visualisation and offer suggestions of how to better represent the netflow data.
Specific additions to the netflow visualisation include:
Provide a mechanism for Authenication, Authorisation and Auditing of the visitors and users on the webpage.
Current backend scripts are written in perl/cgi. They should be understood and suggestions given in terms of code refactorisation and redesigned to provide a more uniform api for the frontend to access the information.
It is suggested that the perl Template library be used to separate the presentation of the dynamic webpages from the code. In particular, emphasis should be put on unit testing of individual components.
Provide a tabular interface on the main page in order to provide ajax based pages for:
Furthermore, the web site should be made consistent and professional looking, with facilities to allow easy customization.
Such as using CPAN.
The code should be kept upto date on the SLAC SVN. The project applicant should apply for a computer account at SLAC here and contribute towards the wiki page (such as Terapaths Monitoring Front End Developers Manual).
