<![CDATA[GetDCI]]>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:

return 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

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

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)?

Then i tried your script:

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

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

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

if (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 🙂

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.

Victor
