SrvReport is a simple and featurefull server monitoring and reporting
system. It will send every day a mail with the latest
state of the server including traffic (via /proc/net/dev and/or iptables), cpu, mail, http, ftp reports
and other logs.
mrtg-eth is a perl script which provides a probe for the Multi Router Traffic Grapher to print statistics for network devices which do not support the SNMP protocol. It reads if-stats from /proc/net/dev and generates an output suitable for MRTG.
