What is the best way to monitor the total incoming / outcoming

monitor the network interfaces and to send SNMP packets to remote
server. But is it possible?

Absolutely. Check out Cacti http://cacti.net/

There are lots of alternatives to Cacti too (MRTG, even doing graphing in your system monitoring tool like Nagios.) You might also find it easier to monitor the switch instead of the servers if that's possible with your gear. This way, you configure the switch once and can monitor all the servers on it instead of having to configure each server individually to allow snmp access.

OpenNMS is good too, if you have enough devices to be worth the extra complexity. Http://www.opennms.org.
