Starting hardware instrumentation services (HIS)

For IBM System z10 or later machines, use the START hisproc command to:

Start the hardware instrumentation services (HIS) address space
Create a new instrumentation started task, hisproc

Hardware instrumentation services (HIS) is a function that collects hardware event data for processors in SMF records type 113, as well as a z/OS UNIX System Services output files. You can only use HIS for IBM System z10 or later machines.

You must start the HIS address space on each system where you want to collect data. Then you must configure and activate the HIS Profiler (hardware event counters and sampling facilities) for each system by issuing the MODIFY hisproc, BEGIN command. See the following references:

Setting up hardware event data collection for more information about setting up hardware event data collection services.
Starting, configuring, and stopping hardware event data collection for information about the MODIFY hisproc command.

Note that it is important to assign a sufficiently high dispatch priority to the instrumentation started task hisproc. This will allow the HIS Profiler to write the sampling data to the .SMP output files in a timely manner.

 
S hisproc

The parameters are:

hisproc: The name of the HIS catalogued startup procedure. You can use the HIS member in PROCLIB as your hisproc procedure.

Example:

To start the HIS address space, enter:

S hisproc

After the initialization is complete, the system returns the following message:

HIS002I hisproc INITIALIZATION COMPLETE
