NAME iograph -- create HTML graphs showing network traffic SYNOPSIS iograph [-i interface] [-o outdir] [-d datafile] DESCRIPTION The iograph program collects network statistics for an interface of the lo- cal host and stores the number of sent and received bytes in a small binary database. It then creates HTML pages printing the statistics for one day (hourly dis- play), one month (daily display) or for the past twelve month. The HTML pages print the number of bytes sent / received together with a bar graph. Options -i interface The network interface for which statistics are to be collected. -o outdir Directory where to place the resulting HTML pages. Do not add a trailing slash! -d datafile Name of the database file. Usage iograph is intended to be run as a cron job. Add the following line to your system crontab(8): 0 * * * * root /usr/local/bin/iograph -i ath0 -o /usr/local/www/iograph -d /var/db/iograph.dat AUTHORS Markus Dolze <bsdfan@nurfuerspam.de> BUGS The intended interval is one hour. If it is called more than once an hour, the data point for the past hour is overwritten with the traffic since the last run. On i386 systems, FreeBSD's network counters are 32 bit long, therefore wrapping at 4 GB. iograph will produce wrong results if more than 4 GB are transfered within one hour, because it can only detect one counter wrap.
