This document outlines a project to develop a web-based network monitoring system using SNMP. It discusses motivations like the popularity of SNMP and the need for affordable, easy-to-use monitoring tools. The system will allow real-time visualization of network status via a web GUI. Existing open-source monitoring tools are reviewed along with their limitations regarding graphing, alerting, and real-time monitoring capabilities. The proposed system's scope, timeline, and conclusions are presented, along with references.

Motivation
SNMP has become the most popular network management
protocol for its simplicity and scalability.[3]
A well-monitored network gives oragnizational managers the
proactive infrastructure and reduces the work of Network
Administrator[6]
Tools like Cacti and OP Manager use SNMP for quering
devices
Lot of GPL and Commercial NMS’s are available
Open Source tools do not fulfill the Administrator
requirements
NMS should be affordable and Easy to install and use [6].

Problem Definition
Designing a web based GUI to monitor network supporting
ubiquitous access and real-time visualization of network using
SNMP protocol. So as to give the Network admin, a freedom
to monitor the whole organization’s network at his own desk
Which has
net-SNMP quering[1]
real-time uplink and downlink network status
has graphical representation of results
alarming system

Network Monitoring System
NMS is a combination system of hardware and software
functioning as monitoring and administering tools for
heterogeneous networks[7].
Simple Network Management Protocol (SNMP) is commonly
used within NMS[8]
In a round-robin database (RRD) usually time-series data like
network bandwidth, temperatures, CPU load etc. is stored.

SNMPv1 :Simple Network Management Protocol
(RFC1213)has MIB2
SNMPv2c: (RFC1907) includes security, confidentiality
SNMPv3 :(RFC2275)addition of cryptographic security
ensures confidentiality,integrity and authentication[7]
It is Internet-standard protocol for managing devices on IP

Overview of SNMP Architecture
An SNMP-managed network includes management stations
and network devices[4]
Agent software which runs on managed devices
Network management system (NMS) software which runs on
the manager
MIB (Management Information Base), can monitor the state
of hardware and software, and the running state of the
system[3].)

Net-SNMP is a suite of applications used to implement
SNMPv1, SNMPv2c and SNMPv3 using both IPv4 and
IPv6[8]
A library for developing new SNMP applications, with both C
and perl APIs
Network management system (NMS) software which runs on
the manager
Information from snmp enabled device is collected by
commands like[8]
snmpget

IPRs existing NMS
CACTI
Open Source and Create graphs using RRD tool
MySQL database as backend and the frontend is PHP driven

clients and NSClient++ is used to monitor Windows Clients
Monitoring via remotely run scripts made in
C++,perl,Ruby,Python

Conclusion
Considering the features of SNMP like flexibility and simplicity
and less load, A SNMP based Network monitoring system is
designed which can support for ubiquotous access, by quering
the network devices from time to time Real-time visualization
of network status will be achieved with graphs ploting the disk
usage,memeory usage,logged in users and ping utility.
