Post subject:  Partition free space as percentage
To me a listing of partitions with x MB free space is less meaning than a percentage of the partition free. A partition with less than 10% free will suffer somewhat if it is a system partition. I made a few changes to the code to allow this to happen, let me know if this is a good idea. Another thought I had but haven't implemented is to switch between MB and % in the config, or even include both.

index.php
[code]
DisplaySection('f4',__("Partition free space less than ").$partition_free_space.__(" MB"),'PartitionUsage','Partitions');
[/code]
change to
[code]
DisplaySection('f4',__("Partition free space less than ").$partition_free_space.__(" %"),'PartitionUsage','Partitions');
[/code]

admin_config.php
[code]
echo "<div class=\"npb_config_col\">".__("MB").":<input type='text' name='partition_free_space_post' size='4' value='$partition_free_space'></div><br >";
[/code]
change to
[code]
echo "<div class=\"npb_config_col\">".__("%").":<input type='text' name='partition_free_space_post' size='3' value='$partition_free_space'></div><br >";
[/code]

index_data.php
[code]
function GetPartitionUsageData($id)
{
global $db, $partition_free_space;
$tr_class='npb_highlight_row';

$sql = "SELECT sys.system_name, sys.net_ip_address, par.partition_uuid, par.partition_volume_name, par.partition_caption, par.partition_free_space, par.partition_size, par.partition_timestamp ";
$sql .= "FROM system sys, partition par ";
$sql .= "WHERE par.partition_free_space < '$partition_free_space' AND sys.system_uuid = par.partition_uuid AND par.partition_timestamp = sys.system_timestamp ";
$sql .= "ORDER BY sys.system_name, par.partition_caption";
[/code]
change to
[code]
function GetPartitionUsageData($id)
{
global $db, $partition_free_space;
$tr_class='npb_highlight_row';
$partition_percent = $partition_free_space *.01;

$sql = "SELECT sys.system_name, sys.net_ip_address, par.partition_uuid, par.partition_volume_name, par.partition_caption, par.partition_free_space, par.partition_size, par.partition_timestamp ";
$sql .= "FROM system sys, partition par ";
$sql .= "WHERE (par.partition_free_space / par.partition_size) < '$partition_percent' AND sys.system_uuid = par.partition_uuid AND par.partition_timestamp = sys.system_timestamp ";
$sql .= "ORDER BY sys.system_name, par.partition_caption";
[/code]

I don't know how much performance impact it will have to do the math 'on the fly' in the SQL but with my 350 systems it didn't do much of any difference.
