CONTENTS NAME SYNOPSIS DESCRIPTION REQUIREMENTS INSTALL EXAMPLE OUTPUT FAQ LICENSE FEEDBACK AUTHOR EOF NAME dfeta -- Disk Freespace ETA Estimation SYNOPSIS dfeta sample dfeta -d /usr/bin/df dfeta dfeta -h DESCRIPTION dfeta samples disk freespace information on regular periods. then it can show (rough) estimate time when disk/device will be full. to sample current status (free space) on all local filesystems: dfeta sample to get estimates for the sampled filesystems: dfeta eta or just: dfeta 'dfeta sample' is supposed to be run on regular basis (for example from the crontab). to attach it to every hour in the crontab you need to enter this line: 0 * * * * /usr/local/bin/dfeta sample dfeta holds current statistics in: $HOME/.dfeta/data each 'sample' command will backup previous data file. REQUIREMENTS dfeta needs Perl. it is pure perl implementation and uses the following perl modules: Data::Dumper Storable Math::BigFloat all of them should be standard and packed inside the Perl package you have installed. INSTALL install is simple. just put dfeta file in your visible executables path. for example one of: /usr/local/bin /usr/bin ~/bin EXAMPLE OUTPUT Device | Mount point | Estimate full at | Full in | /dev/sda2 | / | [never] | [n/a] | /dev/sdb2 | /third | Fri Sep 3 2010 | in 2 months | /dev/sde2 | /home/cade/back | Mon Apr 14 2011 | in 9 months | FAQ Q: what estimation algorithm is used? A: currently only linear regression is used. more algorithms will be added in the future. no additional sampling will be needed for other algorithms. just keeps your sampling regular!
