Informix Auditing for Stored Procedure execution

ello, I am using IDS 11.70.FC4 on Solaris and I am trying to use Informix auditing to capture what stored procedures are being used by client applications/jobs etc. I have created a default mask to capture the event "EXSP". It does a fine job as long as a user executes a stored procedure. What it fails to capture is, when the stored procedure executes a different stored procedure within itself. Am I missing something obvious here? > onaudit -o -yOnaudit -- Audit Subsystem Configuration Utility _default - EXSP > onshowaudit -l ONSHOWAUDIT Secure Audit Utility INFORMIX-SQL Version 11.70.FC4 ONLN|2012-08-08 12:18:36.174|tickdb11|27733|i_hamlet|informix|0|EXSP|tickdb|498|||||||| Please help. regards, Nitin
