Collector Command
Establishes the collection of vector processor instruction counts
at specified program locations.
Format
SET VCOUNTERS [nodespec [,nodepsec...]]
1 – Parameters
nodespec
Specifies a set of restricted program locations that gatehr
vector processor instruction counts within the specified range.
2 – Description
The SET VCOUNTERS Collector command enables the counting of
vector processor instructions. The collected data can help you
determine to what extent the vector processor is being used. You
must specify at least one node specification on the command line
to indicate the domain of the data to be collected.
The following node specifications are used when collecting vector
instruction counts:
o PROGRAM ADDRESS by VINSTRUCTION
o MODULE module-name by VINSTRUCTION
o ROUTINE routine-name by VINSTRUCTION
3 – Qualifiers
3.1 /STACK_PCS
Specifies that stack PC values for counter data are to be
collected. If you use /STACK_PCS, further SET VCOUNTERS requests
assume a default of /STACK_PCS.
3.2 /NOSTACK_PCS
Specifies that no stack PC values for counter data are to be
collected. This is the default setting upon entry into the
Collector.
