NetXMS Support Forum

Hi Viktor and co

Have a NetXMS 2.0.1 system in Server/Remote Agent w/Sites configuration

Have a simple data transformation question.
I'm trying to monitor temperature of some Mikrotik routerboards with SNMP via .1.3.6.1.4.1.14988.1.1.3.10.0

I need to transform the value that the Mikrotik reports by dividing the value by 10.
I've entered the following values in the Transformation option.

Simple Delta

sub main()
{
   return $1 / 10;
}



Test returns the correct results however values received by in the Last Values tab or DCI History return results of 0


Anything I'm missing here ?


Thanks

Hi!


return $1/10;

Is enough actually, you dont need to declare an explicit main() method/function.
See this: https://wiki.netxms.org/wiki/UM:NetXMS_Scripting_Language_(NXSL)#Script_entry_point

As for why you are seeing 0 in last values, you have "Simple delta" as delta calculation enabled.
Set delta calculation to None, and it will work.

$1/10

will work as well (note missing ";" in the end, that's on purpose)

Yikes I feel embarrassed now   
Setting the delta calculation to zero sorted it right out.
I'll have to re-read the wiki again to make sure I'm understanding it right.


Thanks tomaskir and Alex for the quick help.
