CollBufferpool :
============
The CollBufferpool collector collects information for the DB2UDB_BUFFERPOOL application class and provides the values for monitoring DB2 buffer pools.
Note:
For the CollBufferpool collector parameters to be online, you need to set the monitor switch, DFT_MON_BUFPOOL to ON. Log on as the instance owner, and execute the following command:
db2 update monitor switches using BUFFERPOOL ON 版本8
db2 update dbm cfg using DFT_MON_BUFPOOL ON 版本9/10
