check if conx to Net::RabbitMQ is still alive

perl_help26 has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I have a rabbitmq server running on an external server node. My problem is that if I don't communicate with the rabbitmq server for a certain amount of time, the server will kill the connexion which will kill my perl script. Is there a method to know if the timeout has been reached (when requesting something from the rabbitmq) or a flag like 'is_connected'? That way I could reconnect everytime this happens.

Also, if i set a param value for heartbeat for example heartbeat=>60, will this ping the server every 30 seconds and will my problem be solved? Thanks

 my $res = $rabbit_mq->publish(1, "my_exchange.lookup", $bin, {exchang
+e=>'my_exchange'}, {reply_to => $rabbit_mq->{replyQ},});
#####in here if timeout has been reached reconnect
#####or if the cnx is dead reconnect
$res = $rabbit_mq->recv();

It looks to me like the heartbeat parameter will determine how often you need to send a heartbeat frame; it's up to you to make sure that happens. I don't see that there is a way to get the server to tell you it's about to disconnect. You need to store somewhere in your program the last time you interacted with the server.

So I need to say somewhere in my code : if X amount of time has passed $rabbitmq->heartbeat() ? is this what you mean ? Or setting the param will do this by itself?	[reply]

Yes. It will not automatically send the heartbeat. The RabbitMQ documentation indicates that heartbeating is intended to allow for quicker detection of a lost connection. Any activity on the connection counts as a heartbeat; you only need to send an explicit beat if nothing else is happening.
