Nagios Graph converting figures to binary bytes rather than decimal

You will have to manually add an entry into the 'map' file to tell
nagiosgraph to use different values.

My system (df -h) shows:
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg0-root   20G  5.4G   14G  29% /

Nagiosgraph shows:
total: 20.32G
used: 5.45G

You can use the following map entry:

# Service Type: check_disk
# Nagiosgraph regex by Claudio Kuenzler
# Check: /usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /
# Output: DISK OK - free space: / 235120 MB (66% inode=95%):
# Perfdata: /=119211MB;298635;335964;0;373294
/perfdata:(.*)=(\d+)MB;(\d+);(\d+);(\d+);(\d+).*/
#/perfdata:(\W)=(\d+)MB;(\d+);(\d+);(\d+);(\d+).*/ # only / partition
and push @s, [diskusage,
        ['used', GAUGE, $2*1000**2 ],
        ['total', GAUGE, $6*1000**2 ] ];
