Plotting traffic graphs is one of the most popular UNIX admin tasks.
MRTG is a great tool and it is widely used for plotting traffic graphs.
It can be easily set up to plot statistics for any SNMP-enabled device
(including Linux servers running snmpd). But sometimes we can not setup
snmp daemon in Linux server because of small amount of memory or because
of some another reasons. How we can plot our favourite graphs in such cases?
When I have installed my home server to connect my home network to
Internet, there was too small amount of RAM and spending free memory to
run snmpd was not possible. As a solution I have created small Perl
script, that can get information from /proc/net/dev and pass it to mrtg
script.
