[SNMP4J] catch GETBULK for dynamic table

[Alexander Fooks]

Hi, Frank,

Thanks for your answer.

I did exactly as in Snmp4jLogMib.java and I want to fill the table each
time when received GETBULK request:

Object updateSource = null;
public void lookupEvent(MOServerLookupEvent event) {

      if (event.getLookupResult() == this.alCustomEntry && 
          (!DefaultMOQuery.isSameSource(event.getQuery(),
updateSource))) {
    	  updateSource = event.getSource();
        //   
        fillTableFromDB();
      }
      

}


But it entered at endless loop on each GETBULK request.
Would you advise how to define "if" for this permanent case if it's
possible.
and where I may wipe the data in table when response has been sent?

Thank you.

Hi Alexander,

The get method is not accessed when a GETBULK SNMP request
is being processed. Instead you would have to overwrite
the next(..) method. But this only works, if you have a
stable first and last row in your table which is seldom
the case.

I would recommend using the MOServerLookupEvent described
on page 17 and 18 of the instrumentation how-to instead.

Best regards,
Frank
