IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB
totals for hours/days and months. It is intended to be simple, fast
(support thousands of interfaces) and integrate well with MRTG (not required). Data for
each host is updated hourly and HTML graphs are created. It uses a
data consolidation algorithm which allows for a small, non-growing
database file for each host. Perl is required, no external graphing libs or
binaries are needed.
Please send results, bugs or comments to iog@dynw.com.
Especially report performance results if you are using IOG with a large number of ports.
