Do you have a significant amount of work coming into your Db2 for z/OS subsystems through the Distributed Data Facility?
Statistics event monitors are an extremely useful way to get periodic monitoring of basic metrics on your system. They're just well-disguised behind a somewhat misleading name.
You can create profiles to selectively control groups of distributed (DBAT) threads and connections, set thresholds for query acceleration (not covered in this article) or provide override properties to model your test subsystem to reflect the computing power of your production environment.
I have a question about the total_extended_latch_wait_time monitor element. We recently saw high values of total_extended_latch_wait_time and we'd like to understand how to interpret this.
For those of you who use or like db2top, the new dsmtop tool is worth trying out!
