And what about cpu/network/disk utilization ? And load factors per bolt
from storm UI ?

Hi,
Daily we are downloaded 28 Million of messages and Monthly it goes up to
800+ million.
We want to process this amount of data through our kafka and storm cluster
and would like to store in HBase cluster.
We are targeting to process one month of data in one day. Is it possible?
We have setup our cluster thinking that we can process million of messages
in one sec as mentioned on web. Unfortunately, we have ended-up with
processing only 1200-1700 message per second. if we continue with this
speed than it will take min 10 days to process 30 days of data, which is
the relevant solution in our case.
I suspect that we have to change some configuration to achieve this goal.
Looking for help from experts to support me in achieving this task.
*Kafka Cluster:*
Kafka is running on two dedicated machines with 48 GB of RAM and 2TB of
storage. We have total 11 nodes kafka cluster spread across these two
servers.

*Storm Cluster:*
Storm is running with 5 supervisor and 1 nimbus on IBM servers with 48 GB
of RAM and 8TB of storage. These servers are shared with hbase cluster.
*Kafka spout configuration*
kafkaConfig.bufferSizeBytes = 1024*1024*8;
kafkaConfig.fetchSizeBytes = 1024*1024*4;
kafkaConfig.forceFromStart = true;
*Topology: StormTopology*

Please let me know if more information needed..
Thanks in advance.
