You are right. It is count of messages in all topics that have been received by the broker since the broker process started. It is just counter value that get incremented each time a new message is received by broker. The value is reset to 0 when broker is restarted. Also the message count will not be decremented if any message is deleted from broker.
As the name "AllTopics*MessagesIn*PerSec" indicates, It is count of message requests coming into broker not stored into broker.

You are right,it gives the count of mesages stored in all topics from the time the Broker service(Kafka) is started and thats why its actually no of msg request coming to each broker.So whenever a broker service is restarted,message count is set to zero. Also this is the reason,msg count doesn't get decrease when msg is deleted from Broker.
Thanks for clearing my big doubt. On Wed, Nov 20, 2013 at 11:29 PM, Hanish Bansal < [EMAIL PROTECTED]> wrote: *Moniii*
Yes,in jconsole the Mbean "kafka.server":type="BrokerTopicMetrics",contains all the details for all the topics of each machine/broker.
To sum up the number of message for a topic,you will have to go on jconsole of each broker of your cluster and get the count of MessageIn from each Mbean "kafka.server":type="BrokerTopicMetrics",name="*topicName*" and add all the count value.

Also, correct me if I am wrong, but I believe that these count values are the total number of messages seen for a topic (or all topics) since the Broker was started, not the total number of messages stored.

Hi, The count in the Mbean "kafka.server":type="BrokerTopicMetrics",name="AllTopicsMessagesInPerSec" gives the total no of messages for all the topics on the broker. On Tue, Nov 19, 2013 at 8:13 PM, Andrew Otto <[EMAIL PROTECTED]> wrote:
Are you sure? I think it gives the count of messages in all topics that have been received by the broker since the broker process started. If I restart the broker process, the counts all reset to 0 and then start incrementing again. On Nov 19, 2013, at 12:56 PM, Monika Garg <[EMAIL PROTECTED]> wrote:
