<![CDATA[Template DCI & Instance name in transformation script]]>Is there a way to insert the {instance-name} into a transformation script?  I have a Dummy DCI, "Total traffic on {instance-name} (bits/sec)" that sums 2 other DCIs and returns sum.  I'd like to apply this DCI via templates.

Template DCI transformation script:

In = GetDCIValue($node, FindDCIByDescription($node, "Inbound traffic on " . {instance-name} . " (bits/sec)"));
Out = GetDCIValue($node, FindDCIByDescription($node, "Outbound traffic on " . {instance-name} . " (bits/sec)"));
if ( In == null && Out == null )
	return 0;
if ( In == null && Out != null )
	return Out;
if ( In != null && Out == null )
	return In;
return In + Out;

Template DCI Instance Discovery:
SNMP Walk - OIDs
Base SNMP OID:  .1.3.6.1.2.1.31.1.1.1.1
Filter script:return %(true, $1, $2);

I've tried replacing {instance-name} with $2 but no luck.  Any help is appreciated.

You can find class description here: https://wiki.netxms.org/wiki/NXSL:DCI. Instance is it's attribute.

Transformation scripts in templates never executed - it is just a template for real DCIs.

It is not possible to disable DCI from script.

snmp = CreateSNMPTransport($node);
if (snmp == null)
	$dci->status = 1;
oid = ".1.3.6.1.2.1.2.2.1.8." . $1;
ifOper = SNMPGetValue(snmp, oid);
if ( ifOper != 1 )
	$dci->status = 1; }
return %(true, $1, $2);

This is supposed to check ifOper status and disable the DCI of the status is not UP.

Again, thanks for your help!!

try to use $dci->instance like this:

In = GetDCIValue($node, FindDCIByDescription($node, "Inbound traffic on " . $dci->instance . " (bits/sec)"));
[code]

Best regards,
Victor

In your case, you need additional some string operations.
