From last fewdays , i was tying to configure a Linux system to monitor my Lab Network and services. There is not any much information available on net. There are few networking tools avalable, so I thought to give them a try and here are tehe details fo them.
I tried these three tools:
The Multi Router Traffic Grapher, or just simply MRTG is free s/w for monitoring and measuring the traffic load on networklinks. It allows the user to see traffic load on a network over time in graphical form.MRTG uses the Simple Network Management Protocol (SNMP) to send requests with two object identifiers (OIDs) to a device. The device, which must be SNMP-enabled, will have a management information base (MIB) to look up the OIDs specified.
Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. Munin presents output in graphs through a web interface.
Nagios is an open source computer system monitoring, network monitoring and infrastructure monitoring software application. Nagios offers monitoring and alerting services for servers, switches, applications, and services. It alerts the users when things go wrong and alerts them a second time when the problem has been resolved.
I installed this on Ubuntu 12.04. Installation and Configuration steps are in my others posts.
