snmpOID is no longer returning the OID starting with dot

[lhpaladin]

Hi,

$node.snmpOID

is no longer returning the OID starting with dot (.) , many scripts will need adjustments in version 5.0.
Is it a bug or implementation change?

[Filipp Sudanov]

This is intended change. We keep list of breaking changes in the documentation, it's worth checking prior to upgrade:

Thanks for the answer. It's better

Does this mean, that using OIDs in SNMP-requests as functionparameter also have to be done without leading "."?

What is the behavior if result of a SNMP-request is an OID itsself? Is this value returned without leading "."?

[Filipp Sudanov]

NXSL functions accept OIDs both with and without the leading dot. Returned values are without the dot. So both of below lines will print "System description: 1.3.6.1.4.1.14988.1"

println("System description: " .. $node.createSNMPTransport()?.getValue(".1.3.6.1.2.1.1.2.0") );
println("System description: " .. $node.createSNMPTransport()?.getValue("1.3.6.1.2.1.1.2.0") );

?. is safe dereference which appeared in 5.0 - should createSNMPTransport() return null, this will not produce script error.
