<![CDATA[Integer overflow after a transformation?]]>I have a DCI which collects a snmp value. The node presents this value via snmp in kilobytes as an Integer.

I want to see this value in NetXMS in bytes. So I apply a transformation:
return ($1 * 1024);

The problem is that the value then gets reported by NetXMS as -145752064

I have a feeling the Integer is overflowing after the transformation.

Is there any way to get around this?

Thanks!

Try to set the data type of the DCI to "Integer 64 bit" and use this transformation script:

return (int64($1) * 1024);

That did the trick, thanks!
