1. Description of monitoring system
1.1 Introduction
R-SeeNet is the monitoring system, which allows you to monitor all types of B&B routers.
This system consists of two separate program parts. First one ensures reading out statistics
from routers. This program runs as a service and uses SNMP protocol (for reading out statis-
tics). This data is stored in a MySQL database. The database of monitoring system consists of
two main tables. Devices table contains the data about individual routers. Stats table contains
one statistic for each router. This table is updated whenever the routers are reading. Reading
period can be chosen during installation and must be chosen with regard to the number of
routers. The second part is a web browser that is used to display statistical data.
To manage the monitoring system and display results of monitoring routers is used web
interface. Users of this web interface are distinguished based on user permissions. By default
there are a user with administrative privileges (administrator) and a normal user (user). Only
the administrator has the right to add a new user and assign administrative privileges (also to
existing users). There is also a user account known as superadmin, which is used for man-
aging multiple companies. In this case, R-SeeNet is operated by one of the companies and
other companies perceive it as a cloud. Individual companies cannot be entwined. The R-
SeeNet databases management within the all companies will be allowed only for superadmin.
Other users (administrator and user) have access to tables and statistics within the company
to which they belong.
1.2 Hardware requirements
Hardware requirements for the computer on which the R-SeeNet is running depend on the
number of monitored routers. For common number of routers (to one thousand) is sufficient
office PC with 2 to 4 GB of memory and processor Intel Core i5. For larger numbers of moni-
tored routers is recommended a server computer with at least 2 processors, 10 GB of memory
and large fast disks due to frequent access to the database.
1.3 Data traffic
When monitoring system is reading the router through SNMP protocol, router sends 452 B
and receives 495 B. This means that one router sends 2.69 MB per month, when the R-SeeNet
reads out the router every 15 minutes.
