[BackupPC-devel] [patch] [4.0.0alpha2] Pool graphs

[Alexander Moisseev]

This patch adds the pool size graphs on the server status page for privileged users.
RRDtool required to store pool size statistics and show graphs.
If RRDtool not installed, status page looks as usual without graphs.
The graphs updates during the 'backuppc nightly' run.

Main difference from V3:
V3 draws pool+cpool as one area (http://sourceforge.net/mailarchive/message.php?msg_id=30758627);
V4 draws nonempty pools (poolv3, cpoolv3, poolv4, cpoolv4) as stack of areas (see attached BackupPC_Pool_Size.png).

Attachedpatch-4.0.0alpha2-rrd.tar.gz contains patches against bin/BackupPC and lib/BackupPC/CGI/GeneralInfo.pm

Note that RRD data sources (DS) renamed and 3 new DS added.
If you have existing RRD created by BackupPC V3, execute conversion script rrd_2_v4.pl in directory where the pool.rrd resides, usually $LogDir (/var/log/BackupPC). You will need RRD::Simple to run rrd_2_v4.pl.

Alexander,

Thanks for the patch. I've included this in 4.0.0, and it will be in the
next alpha3 version, which hopefully I will release next weekend.

I implemented it slightly differently, including moving all the rrd code to
a new utility that BackupPC executes daily (after BackupPC_nightly) in the
background (to avoid blocking by doing a system()), but it is largely based
on your code. It also generates and saves the graphs, rather than creating
them on-the-fly.

I also changed the existing status reporting to use GiB (2^30) and MiB
(2^20) to match the numbers in the graphs.
