in reply to Error handling in AnyEvent::SNMP

can you try replacing the $cv->begin, $cv->end with a single $cv->send where the $cv->end is?

Additionally, can you check the return of get_table(), if I read the following right:

When a Net::SNMP object is created having non-blocking behavior, the invocation of a method associated with the object returns immediately, allowing the flow of the code to continue. When a method is invoked that would initiate a SNMP protocol exchange requiring a response, either a true value (i.e. 0x1) is returned immediately or the undefined value is returned if there was a failure. The error() method can be used to determine the cause of the failure.

    Thanks, but that doesn't work, it only makes the snmp request on the first OID in the loop
    if I force an error, not using an event loop (just snmp non-blocking mode) for example, 
    $session->get_table(
                        -baseoid => $snmp_table,
                        -maxrepetitions => 1,
                        -callback       =>  sub{ 
                                                    #print "get_sub\n"
+;
                                                    $hosts{$host}{oid_
+results_table}->{$snmp_table}= &snmp_collect(@_); 
                                                    #$cv->end;
                                                
                                            } 
                                            
                            )

    The error The max-repetitions argument is not applicable when using SNMPv1 is returned
    When implemented in the AnyEvent loop the script hangs. Any ideas?

      where is the $cv->send ?
