Auto-scaling for RPM (fan data)

[djack]

For collect fan data and display RPM (not KRPM) on zabbix screens, you should change in module func.inc.php function: convert_units(). It was tested in Zabbix 1.8.2 and 1.8.3.
You should add lines in bold:

function convert_units($value, $units, $convert=ITEM_CONVERT_WITH_UNITS){
............
............
switch($units){
case 'RPM':
$step=1;
$convert = $convert?$convert:ITEM_CONVERT_NO_UNITS;
break;
case 'Bps':
case 'B':
$step=1024;
$convert = $convert?$convert:ITEM_CONVERT_NO_UNITS;
break;
case 'b':
case 'bps':
$convert = $convert?$convert:ITEM_CONVERT_NO_UNITS;
default:
$step = 1000;
}
............
............
if ($units=='RPM') $desc='';
return sprintf($format, $valUnit['value'], $desc, $units);
}

for the record, 1.8.3 blacklists uppercase & lowercase rpm for multiplier prefixes already
