Fire an event every time there is a set

Hi frank, I have an agent generated by agenpro. Is there a way to fire an event when a set to the mib is detected?

Sure, you can use the the MOLookupListener interface and add your implementation to DefaultMOServer by DefaultMOServer (SNMP4J-Agent 3.6.0)
With the MOServerLookupEvent.getIntendedUse (MOServerLookupEvent (SNMP4J-Agent 3.6.0)) method you can find out if a write operation (i.e., SET request) has triggered the lookup.

Hi frank, I’m kinda of a newbie with this matter, is there any example on how to do that?

Sure see:

Hi Frank, after reading the documentation I still don’t quite get it, can you show me a quick exemple where I send a snmpset to a table and the event fired is just a simple print of the value and the OID? I already get the fact that you need to use MOServerLookupEvent.getIntendedUse in the lookupEvent method of the listener, but how can I get the OID of the table looked up ?
Thanks in advance for the help and atention.

You can print the variable binding from the Request:

public void lookupEvent(MOServerLookupEvent event) {
    if (event.getQuery() instanceof MOQueryWithSource) {

Okay, that makes sense, I’m going to try it. Just one more question, I still don’t know what I need to pass in the second argument of the addLookupListener , the ManagedObject<?>, can you help?

That ManagedObject is the MOScalar or DefaultMOTable for which you are interested. Thus you will be called back if this ManagedObject is being looked up for processing a SNMP request.
But for GETNEXT and GETBULK, this not necessarily means that this ManagedObject will actually process the request, for example if the table is empty.

Hi again Frank, is there a way of checking if the request sent is a get or a set?
I’m asking because I need to fire different methods depending on the type.
Thanks a lot for the help.

Sure, you can evaluate MOServerLookupEvent.getIntendedUse:
