AW: check active queries on cluster
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, geoarea, ver) VALUES (?, ?, ?, ?);, v=2 TRACE [Native-Transport-Requests:167] 2015-06-01 15:56:15,187 QueryProcessor.java (line 283) Stored prepared statement 61956319a6d7c84c25414c96edf6e38c with 4 bind markers DEBUG [Native-Transport-Requests:167] 2015-06-01 15:56:15,187 Tracing.java (line 159) request complete DEBUG [Native-Transport-Requests:167] 2015-06-01 15:56:15,187 Message.java (line 309) Responding: RESULT PREPARED 61956319a6d7c84c25414c96edf6e38c [leid(dba_test, cust_view), org.apache.cassandra.db.marshal.UTF8Type][vid(dba_test, cust_view), org.apache.cassandra.db.marshal.UTF8Type][geoarea(dba_test, cust_view), org.apache.cassandra.db.marshal.UTF8Type][ver(dba_test, cust_view), org.apache.cassandra.db.marshal.LongType] (resultMetadata=[0 columns]), v=2 Von: Robert Coli [mailto:rc...@eventbrite.com] Gesendet: Freitag, 17.

Re: check active queries on cluster
A warning on enabling debug and trace logging on the write path. You will be writing information about every query to disk. If you have any significant volume of requests going through the nodes things will get slow pretty quickly. At least with C* 2.1 and using the default logging config.
