How GPA Works
GPA bases its analysis on system performance data collected by Measure and on the GPA
internal model of a NonStop system multiprocessor node.
As distributed, GPA consists of these files:

GPAGOBJ or GPAHOBJ is the foundation process or wrapper which performs the
initialization, multiple node license check, handling different Measure versions,
creation of the entity files for GPA analysis then programmatically calling the proper
GPA module for processing (e.g. GPAG or GPAH). The GPAGOBJ and GPAG are
specific to systems running the G version of Guardian OS. The GPAHOBJ and
GPAH are specific to systems running the H or J version of Guardian OS.

GPAG & GPAH perform the analysis for ZMS+/Legacy format entity files.

TUNEDATA contains coded text statements for the “GPA Analysis Statements”
section of the GPA Standard Report.

OBEYTUNE is the script file (i.e. obey file) used to execute the GPA analysis run
and contains all the runtime parameter options. The user should review the setup of
OBEYTUNE prior to each GPA run to ensure the parameters are aligned with the
analysis objectives.

EXCLUDE contains directives which define which CPUs and processes will be
ex
cluded in GPA‟s performance recommendations.

GLOBAL contains various processor performance attribute variables which are
loaded at runtime. (Note: This file may require updates from time to time as new
processors (i.e. CPU Type/Subtype) are released.)

MAKELIC is a script that creates properly-formatted license file templates (i.e. empty
LICPFILE and LICSFILE files).
