using DCI attributes within transformation script

[gkaudewitz]

Hello together,

is there a way to use attributes of the current DCI within a transformationscript?

For example getting the name-attribute and building out of this an oid with an value that was requested in an other DCI.

Best regards

Georg

$1 - current value (last polled)
if you want use another dci in curent dci see this http://wiki.netxms.org/wiki/NXSL_Function_Reference#Data_Collection

Sorry but I hove to clarify the question. I want to do the following with the Transformatinscript of the DCI

I have an DCI with parameter:
.1.3.6.1.2.1.31.1.1.1.10.10201
from that parameter/name I want to build the parameter
.1.3.6.1.2.1.2.2.1.5.10201
to find the corresponding DCI by GetDCIValueByName that has requested the interface speed.
With this information I want to calculate the percentage value for the usage of the interface within the transformormationscript.

mmm?

sub main()
{
  if ($node->isSNMP)
  {
   transport = CreateSNMPTransport($node);
    if (transport == null)
    {
    return -1;
    }

    ifspeed = SNMPGetValue(transport, ".1.3.6.1.2.1.2.2.1.5.10201"); // get if speed

    if (ifspeed != null)
    {
        //you can use "case/switch" if have y have many params
        if (ifspeed == "blablabla") //change blabla bla string. see mib, i don't know how it on cisco
        {
           return (($1*8)/(1 << 20)); //transform bytes to megabites
        }
        else
        {
           return $1; //return default value
        }
    }
  }
}

Not really what I want to do.
Within transformationscript some pseudocode now
sub main()
{
  pos = rindex(trim($dci->name),".");
  len = length(trim($dci->name)) - pos;
  port = right($dci->name,len);
  snmpoid = ".1.3.6.1.2.1.2.2.1.5.".port;
  speed = GetDCIValueByName($node,snmpoid);
  result = (($1*8)*100)/speed;
  return result;
}

the meaning of $dci in this example would be the same as with $node refering to the current DCI.

$dci object added in 1.2.4 dev version
how get snmp y see in my script.
i'm recomend write script in script library and using functions with "use" operator.

Now we have same understanding of my problem.
Thanks for the information concerning $dci.
This will simplify the tasks concerning calculation of values for me. Because I don't want generating an extra snmprequest each time the octet-value is requested.

Thanks for the help!

if portspeed is constant you can write array with each port information in the script.

Is the $dci object added in final version of 1.2.4?

[victor]

Yes, it is available in 1.2.4.

and in 1.2.4 added multipliers for charts.

and y need only transform bytes to bites
