Creating Multiple Profile Data Files

Creating Multiple Profile Data Files

When you run a program using pc sampling, raw data is collected and saved in the profile data file mon.out. To collect profile data in several files, or to specify a different name for the profile data file, set the environment variable PROFDIR, using the appropriate method from Table 4-2.

Setting a PROFDIR Environment Variable
C shell and tcsh Bourne shell and Korn shell
setenv PROFDIR dirname PROFDIR=dirname; export PROFDIR

Setting a PROFDIR Environment Variable
C shell and tcsh	Bourne shell and Korn shell
setenv PROFDIR dirname	PROFDIR=dirname; export PROFDIR

Setting the environment variable puts the raw profile data of each invocation of progname in files named dirname/progname.mon.pid. (You must create a directory named dirname before you run the program.) pid is the process ID of the executing program; progname is the name of the program when invoked.
