How to monitor db2 executing trigger activity ?

Hi ,
Anyone know how to monitor db2 trigger activity ?

We suffer some trigger issue today and we try to monitor trigger's
behavior use event monitor and db2audit, but both tools can not get
trigger's sql statment and cost, have other tools can get trigger's
executing sql statment and cost ?

our test case as follow:
Env:
WIN XP
DB2 V8 + FP13

1. create sample table
create table DB2.NEWS ( ID INT, NAME CHAR(10),T_TIME timestamp ) IN
TBS16K @

create table DB2.NEWSQ1 ( ID INT, NAME CHAR(10),T_TIME timestamp with
default current timestamp) IN TBS16K @

2. create sample trigger
create trigger DB2.NEWSTRG
after insert on DB2.NEWS
referencing
new as nw_row
for each row
mode db2sql
BEGIN ATOMIC
insert into DB2.NEWSQ1 (ID, NAME)
values ( (nw_row.ID+1000),
nw_row.NAME) ;
END @

3. create event and activate event
create event monitor failtrigger for
tables,
statements,
transactions
write to file 'd:\event' ;
set event monitor failtrigger state 1 ;

4. insert data to DB2.NEWS
db2 "insert into DB2.NEWS values (1,'aa',current timestamp)"

5. check data
db2 "select * from db2.news"
db2 "select * from db2.newsq1"

6.format event
db2evmon -path d:\event

part of event output:
only can get insert sql statement and Internal rows inserted count
but without trigger sql statment.

we also try db2audit, still can not get executing trigger sql
statment.

do anyone know how to monitor db2 trigger executing activity ?
Thanks
