NAME

Net::SNMP::QueryEngine::AnyEvent - multiplexing SNMP query engine client using AnyEvent

VERSION

Version 0.06

SYNOPSIS

This is an AnyEvent-flavored Perl client for snmp-query-engine, a multiplexing SNMP query engine.

    use Net::SNMP::QueryEngine::AnyEvent;

    my $sqe = Net::SNMP::QueryEngine::AnyEvent->new;

    $sqe->setopt("127.0.0.1", 161, { community => "meow" }, sub {});
	$sqe->when_done("127.0.0.1", 161, sub { print "done with localhost\n" });

    $sqe->gettable("127.0.0.1", 161, "1.3.6.1.2.1.1", sub {
      my ($h, $ok, $r) = @_;
      for my $t (@$r) {
        print "$t->[0] => $t->[1]\n";
      }
    });

    $sqe->get("127.0.0.1", 161,
      ["1.3.6.1.2.1.1.5.0", "1.3.6.1.2.1.25.1.1.0"],
      sub {
        my ($h, $ok, $r) = @_;
        print "Hostname: $r->[0][1]\n";
        print "Uptime  : $r->[1][1]\n";
    });

    $sqe->wait;

when_done

Execute provided callback when there are no unfinished get or gettable queries towards a specified host:port.

wait

Enters event loop until there are no unanswered queries. Can be called multiple times.

setopt

Performs setopt request.

get

Performs get request for arbitrary number of OIDs.
