DCI filter script - how to ignore some filesystems when using {instance} ?
-
if (rindex($1,":")>0) // this is for your case.
{
// if(length($1)>3) return false; // in some cases, you can link a disc drive to directory. uncomment this line if you don't want to see them.
if (rindex($1,"A:")>0) return false; // in my case, i have virtual pcs, and some of them have floppy disk drives, i don't want to see them.
value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
return (value != null) && (value > 0);
//return %(true, $1);
}
return false; -

The issue I see with this is when a CD disk does not report its value as ERROR and starts reporting the value as "0". An example of this would be when a CD/DVD is put into the drive and the reported value changes from ERROR to 0 (zero) space available and the threshold alert will be sent.
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; -
Hi,
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,

Most likely next week, or week after in worst case.

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 1,000GB 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.

if ($1 =~ "[:/]") { value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")") return (value > 5*1024*1024*1024 && value < 1*1024*1024*1024*1024); } return false;@sharpspro said in DCI filter script - how to ignore some filesystems when using {instance} ?:

I tried your suggestion and it did not work for me. Currently I'm using a filter script to ignore CD/DVD drives that report as errors when there is no disk inserted as well as system partitions with no drive letter. I got the script from this post please review below.
CURRENT SCRIPTif (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;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.

This script:
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;Best regards,

Some reason that script is not working. I included screen shots maybe I have something wrong.
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;

To filter CD/DVD and Volume in the "Instance Detection" section, I use this script:
type=AgentReadParameter($node, "FileSystem.Type(" . $1 . ")");
if ((type == null) || (type == "") || (type == "CDFS") || (type == "UDF"))
{
return false;
}if (
type != null && (
type == "aufs" ||
type == "autofs" ||
type == "cgroup" ||
type == "configfs" ||
type == "debugfs" ||
type == "devpts" ||
type == "devtmpfs" ||
type == "fusectl" ||
type == "fuse.gvfsd-fuse" ||
type == "fuse.lxcfs" ||
type == "hugetlbfs" ||
type == "iso9660" ||
type == "mqueue" ||
type == "nfsd" ||
type == "overlay" ||
type == "proc" ||
type == "pstore" ||
type == "rpc_pipefs" ||
type == "securityfs" ||
type == "selinuxfs" ||
type == "squashfs" ||
type == "sysfs" ||
type == "tmpfs"
)) {
return false;
}if (($1 == "/proc") ||
($1 like "/proc/*") ||
($1 == "/sys") ||
($1 like "/sys/*") ||
($1 == "/run") ||
($1 like "/run/*") ||
($1 == "/dev") ||
($1 like "*Volume*") ||
($1 like "/dev/*"))
return false;
return true;
