Thanks in advance guys!

When I change the scrpit to the one I used prior and it locates all the drives. That script is below.

if (rindex($1,":")>0)
{
// if(length($1)>3) return false;
if (rindex($1,"A:")>0) return false;
value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
return (value != null) && (value > 0);
//return %(true, $1);
}
return false;

if ($1 =~ "[:/]") {
  value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")")
  return (value > 5*1024*1024*1024 && value < 1*1024*1024*1024*1024);
}
return false;

has few typos - match operation is ~= and semicolon is missing in line 2. It should be

if ($1 ~= "[:/]") {
  value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
  return (value > 5*1024*1024*1024 && value < 1*1024*1024*1024*1024);
}
return false;

SO for the DCI I created I removed the current script I use and I tried your suggestion and it located all drives and didn't filter anything.

NEW SCRIPT

if ($1 =~ "[:/]") {
  value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")")
  return (value > 5*1024*1024*1024 && value < 1*1024*1024*1024*1024);
}
return false;

For the values you suggested (5*1024*1024*1024) is for 5GB I asume and (1*1024*1024*1024*1024) is for 1TB. If I understand this right, if I wanted to filter drives that are 500GB to 1000GB I would use (value > 512*1024*1024*1024 && value < 1*1024*1024*1024*1024) Not sure on this and hope its not a stupid question.

@sharpspro said in DCI filter script - how to ignore some filesystems when using {instance} ?:

Guys,

I'm looking to create a script that will only show drives within a certain size range. For example only show drives that are between 500Gb and 1,000GB or 1,000TB and 1,500GB.

The reason being is that i want to setup thresholds differently on drives. Smaller drives i would like to have a higher percentage free than huge drives. The bigger the drive gets the lower i want the percentage free to alert on the threshold.

Thanks for the reply! When will that version 2.0-M3 be available?

Thanks!

in version 2.0-M3 I've added new parameter FileSystem.Type, so with agent version 2.0-M3 you can filter out CDs as following:

if (rindex($1,":")>0)
{
   type = AgentReadParameter($node, "FileSystem.Type(" . $1 . ")");
   // exclude CDs:
   return (value != null) && (value != "CDFS");
   // if only NTFS systems are of interest (usual situation):
   // return value == "NTFS";
}
return false;

Best regards,
Victor

My question is, is there a way to exclude CD/DVD drives completely with this filter? Or is there another work around to get this accomplished?

Below is how I have the scrpit currently:
if (rindex($1,":")>0)
{
// if(length($1)>3) return false;
if (rindex($1,"A:")>0) return false;
value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
return (value != null) && (value > 0);
//return %(true, $1);
}
return false;

I would like for the drives that do not have drive letters to NOT show up e.g. "Percentage of free space on file system \\?\Volume{xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx}\" ----instead I only want it to show valid drives e.g. "Percentage of free space on file system C:\"

I will continue to search on this but any help is appreciated.

You can create filtering script for instance discovery which will attempt to get total space for file system and only return true if data was read successfully and size is non-zero. It could be something like this:

value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
return (value != null) && (value > 0);

Victor
