db2 pm - report on ts
Hi,
I would like to create a report of reads/writes per tablespace - like this:

BPOOL DATABASE TYPE SYNCH I/O AVG SYN I/O AVG DELAY
SPACENAM GBP ASYNC I/O AVG SYN I/O MAX DELAY
PART ASY I/O PGS AVG
----- -------- ---- --------------- -----------------
BP1 DBTPCCB TSP 8.55 55.00
TITEM000 N 0.02 8961.00
1 1.00
BP1 DBTPCCB IDX 7.02 51.00
XITEM000 N 0.00 5636.00
...

I started statistics trace:
-STA TRACE(STAT) CLASS(1,3,8)

Using DB2 Performance Monitor I issue this command:
STATISTICS
REPORT
DSETSTAT
LAYOUT(LONG)

I get a long report as expected, but no ts statistics.
Do I need to start more traces ? Which ones ?
Thanks in advance,
Daniel
