<div dir="ltr"><div class="gmail_quote"><br><div dir="ltr">Hi<br>I have a the same question!<br>and for the answer of "<i>why do you want the producer to know if there is a consumer around?</i>" I should say: I have about 50 producer and 10 consumer. each producer producing about 500,000 message per day:) In a day it become about 25,000,000 message! I don't want my rabbitMQ server fail because of absence of message consumer. I want to notify my producers to wait and save message in db until consumers are up. so because there are many producers I can't use a passive declare like discussed in <a href="http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2012-June/020553.html">here</a>.<br>
Did I could <span style="text-indent:0px;letter-spacing:normal;font-variant:normal;text-align:-webkit-auto;font-style:normal;display:inline!important;font-weight:normal;float:none;line-height:normal;text-transform:none;font-size:13px;white-space:nowrap;font-family:arial,sans-serif;word-spacing:0px">clarify</span> my problem? <br>
Is here any controller like <a href="http://activemq.apache.org/producer-flow-control.html">Producer Flow Control</a> available? <br>

To answer your question literally: yes, use the mgmt HTTP API.<br>
<br>
To answer your question slightly less literally, the point of a<br>
messaging system is to let producers and consumers become decoupled -<br>
why do you want the producer to know if there is a consumer around?<br>
<br>
