May be it helps...

i tried the way you mention above but not working properly.
Still i am facing the same problem in getting the port name or interface name in DCI description.

percy

I tried to solve this with macro but not sure if instance parameter can be passed to the script...

For that reason every other part of the DCI is normal:

DCI:

Description: ifDescr: %{script:ReturnIfDescr}
Parameter: .1.3.6.1.2.1.2.2.1.10.{instance} // <= value InOctets for ports, taken from the .10 branch
Origin: SNMP
Datatype: Integer
Instance discovery metod: SNMP Walk - OIDs
Base SNMP OID: .1.3.6.1.2.1.2.2.1.10

Script Library:
ReturnIfDescr:

transport = CreateSNMPTransport($node);
if (transport == null) return "n/a";
return SNMPGetValue(transport, ".1.3.6.1.2.1.2.2.1.2.1"); // <= ifDescription of 1st port, taken from the .2 branch

But this script returns only description of the first port to the macro.

There should be something like this, but it does not work this way ofcourse ..

return SNMPGetValue(transport, ".1.3.6.1.2.1.2.2.1.2.".$instance);

p.s. this solution will not reflect any changes in the ifDescription though as the macro is run only when the DCI is created

M.Sperl

And the Datatype in the DCI template configuration should be Integer, not String (not sure if it is the main problem though).

M.Sperl

here {instance} is an Index i.e integer value but we are passing string fa0/0

when i change the Parameter Oid IfName to ifIndex than DCI doesnot show the Interface Name...but give the Values for the DCI.
in this case DCI doesnot shows the interface Name

Description                                    Parameter                                  data Type
Traffic In {instance} (Byte/sec)      .1.3.6.1.2.1.2.2.1.1.{instance}    integer
Traffic In 1 (Byte/sec)                  .1.3.6.1.2.1.2.2.1.1.1                integer
Traffic In 2 (Byte/sec)                  .1.3.6.1.2.1.2.2.1.1.2                integer
Traffic In 3 (Byte/sec)                  .1.3.6.1.2.1.2.2.1.1.3                integer

difficult to find the DCI for the Interface Inteface fa0/1 or if there are many Interfaces difficult to find the DCI for the particular inteface.

trafficIn = SNMPGetValue(transport, ".1.3.6.1.2.1.31.1.1.1.6.$1");

I am not shure, but try to change to:

trafficIn = SNMPGetValue(transport, ".1.3.6.1.2.1.31.1.1.1.6." . $1);
