ModStat

SAT Telecommunications Ltd

Developed by Sergi Joseph, ModStat is a web-based application used by Network Administrators and Field Technicians to monitor nodes and cable modems on the Digicel HFC Network.

The front-end of ModStat was built mainly using PHP, HTML, CSS and JavaScript; while the back-end was built by incorporating a Linux cron job to run a C++ script, which retrieved modem data from a CMTS and stored this data in a MySQL database. The data was displayed on the web interface in tables, graphs and charts to allow a holistic view of the network status. This tool was essential for network operators to monitor network statistics and identify outages in real time.
