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, but no external graphing libraries or binaries are needed.
Release Notes: A bug has been fixed which caused router/switch reboots to potentially cause large negative values for that particular hour. A PHP index script has been added.
Release Notes: This release has a newer SNMP module that fixes compatibility with some switches. A HOWTO is included.
Release Notes: This release fixes a syntax error which caused IOG to not run on some versions of Perl.
Release Notes: A fix for a bug that causes hyperlinks to be created on the previous month's page.
Release Notes: A bug that caused the last day of the month to not be displayed or calculated in the monthly total usage has been fixed.
