You could enable DEBUG logging for org.apache.cassandra.transport.Message and 
TRACE logging for org.apache.cassandra.cql3.QueryProcessor in the 
log4j-server.properties file:

log4j.logger.org.apache.cassandra.transport.Message=DEBUG
log4j.logger.org.apache.cassandra.cql3.QueryProcessor=TRACE

Afterwards you get the following output from all PreparedStatements in the 
system.log file:

DEBUG [Native-Transport-Requests:167] 2015-06-01 15:56:15,186 Message.java 
(line 302) Received: PREPARE INSERT INTO dba_test.cust_view (leid, vid,

We want to track active queries on cassandra cluster. Is there any tool or way 
to find all active queries on cassandra ?

You can get a count of them with :
