onstat -g ntt - in sysmaster

Hi I want to write a query in sysmaster to get the following information:- netscb thread name sid open read write address 2605cdc0 sqlexec 3109 17:59:55 18:00:22 18:00:22 the above is taken from onstat -g ntt I am interested in open, read and write time which I believe pertains to connection open time, last read operation time of connection and last write operation time of connection. I need it to 'prove' to our developers that there is a connection leak in their code which causes useless connection to sit idle doing nothing for hours, while new connections are acquired all the time. This is eventually leading to informix crash. oh yeah,it is a battle between DBA and developers :-) thanks in advance.
