Backend website

The backend opens in hidden link and ask for Login, after successful the landing page in the Dashboard. It shows all the current Complaints and AV Requests. It also shows the new updates and features added to the suite.

From the top bar we can change password, navigate and search. On the sidebar are Event calendar, Noticeboard and many other features, most of which are visible only to administrators and not for other users.

In Complaints and requests page there are two parts: current pending and already done or resolved. Any issue marked done by any user carries the information forward with the time at which it was done. These pages are searchable throughout, with every information from date to name searchable. All the visible data (even the searched data) is downloadable as CSV.

Admins can delete complaints, edit to change the group of a complaint to assign it to the desired users. Admins only can also edit any request to change the date and time of any event — in the Registration form on the frontend it is only possible to register an event 24 hrs before, so this place allows admins to change the date for any exceptions.

Admin features

Manage users and groups feature is only for admins. In Manage users the admin can create or edit new users, give them hierarchy priorities, assign work (by selecting the group that user belongs to), define designation as to be shown on the frontend website in Infocell Team, and also can make a user inactive so they are unable to login but still have all the complaints and requests completed by them in the database.

NMS (Network Management System)

The Dashboard sidebar has a “Live Map” which is in fact the Network Monitoring System. The Map is made by VIZ.js and uses various technologies to build the map. All the visible devices are shown with UP/DOWN status by pinging each device every 5 seconds. The Line UP/DOWN status at the top uses SNMP Trap to show when a line goes down. The left side UTM statistics are taken using SNMP as well as ghost browser login in PhantomJS.
