Network Management Using SNMP

Communication is one the important aspects in human life since thousands of years ago; basically, it is the transfer of information or message between two people, places or machines. Information can also be shared among different computers, routers, switches and between networks. Group of interconnected devices is called Network. Devices include computers, routers, switches, servers etc., thus network allows the sharing of data. In order to have the smooth functionality of network, it has be continuously monitored. So, network monitoring is the major role of network, in which it tries to discern low speed or unsuccessful network devices, such as failing routers, servers, switches and other malfunctioning devices. Network monitoring system cautions the occurrence of a network failure to the Network Administrator (NA). Network monitoring is predominantly put through software tools and applications. The constant and secure supervise of a network includes trace and logs of network parameters. The network parameters include data transmission rate, user-time percentages, downtime of the device, uptime of the device, response time to user and error rates.This paper describes the network monitoring using SNMP (Simple Network Management Protocol), obtaining required system parameters like RAM usage, CPU usage and Disk usage from device which is to be monitored, storing the system values in database and displaying data using Grafana tool
