Hi,

I was wondering whether i can achieve this or not:

I have dci's who shows free disk space and dci's who shows total disk space. For one node there are more than one disk.
What i want is, when alarm ir raised from free disk space threshold, i want to pass the total disk value to event too.
I can achieve this with script:

Quotereturn GetDCIValue($node, FindDCIByName($node, "Filesystem.Total(C:)"));

but this is for one dci with disk C.
So is there a way to use this one script or event for more than one disk, or I must create new script and event for each disk?

Regards,
Nikk

Hi!

In the script you have access to DCI's "instance" field (via $event->instance). If you have correct disk name in that field (and it will be populated automatically if DCI in question was created by instance discovery) you can form correct DCI name for FindDCIByName.

Thanks for solution!

So I tried it, stumpled upon instance discovery filter script. I wanted to get only C and D disks.
I tried this script:

Quoteif (substr($1,1,1) = "C") || (substr($1,1,1) = "D")
{
   return true;
}
else
{
   return false;
}

Seems like i don't get something, please guide me to right path

Looks like typo - you use = instead of == for comparison.

Really, thank you for the obvious mistake

Anyway, i'm still getting the other disks (see 1. screen), maybe the script isn't right.

Then i tried your script:

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

And get rid only of Disk A:, but no disk E: (see 2. screen).

Script looks correct. Could it be that disk E: has non-zero total space (could be the case if this is CD drive with disk inserted or any other read-only device)?

It could be, but I don't have no direct access to that server to check it. Thank you!

You can query FileSystem.Total(E:) using nxget to check it.

Sorry for late answer, been busy.

I checked with nxget and it returned non-zero value.
