Hi Pavan, 1) you cannot read the current number of messages for a topic, but you can read the number of bytes for a topic in Kafka metrics.
2) you cannot read the current number of subscribers directly. However you can read from ZK and parse the results to get the subscriber counts. 3) / 4) I am not sure what you mean by "active" messages and subscription. 5) / 6) You can find this in the Kafka metrics. You can take a look at the list of metrics here: http://kafka.apache.org/documentation.html#monitoring Guozhang On Fri, Jun 5, 2015 at 11:02 AM, Pavan Chenduluru <chendul...@gmail.com> wrote: > Hi, > > I am new to kafka and I have a doubt. > > How to read specified topic statistics from kafka server? > > I want to read below parameters about existing topic from kafka. > > 1) How many activeMessages > 2) How many activeSubscriptions > 3) How many totalMessages > 4) How many totalSubscriptions > 5) How mnay deliveryFaults > 6) How many pendingDelivery > > Pls do the needful. > > Thanks & Regards, > Pavan > -- -- Guozhang
