PMADDPROFILE(3) 					     Library Functions Manual						   PMADDPROFILE(3)

NAME

       pmAddProfile - add instance(s) to the current PMAPI instance profile

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmAddProfile(pmInDom indom, int numinst, int *instlist);

       cc ... -lpcp

DESCRIPTION

       The  set  of  instances	for  performance  metrics returned from a pmFetch(3) call may be filtered or restricted using an instance profile.
       There is one instance profile for each context the application  creates	at  the  Performance  Metrics  Application  Programming  Interface
       (PMAPI(3)), and each instance profile may include instances from one or more instance domains (see pmLookupDesc(3)).

       pmAddProfile may be used to add new instance specifications to the instance profile of the current PMAPI context.

       In  the simplest variant, the list of instances identified by the instlist argument for the indom instance domain are added to the instance
       profile.  The list of instance identifiers contains numinst values.

       The indom value would normally be extracted from a call to pmLookupDesc(3) for a  particular  performance  metric,  and	the  instances	in
       instlist would typically be determined by calls to pmGetInDom(3) or pmLookupInDom(3).

       To select all instances in all instance domains, use

	  pmAddProfile(PM_INDOM_NULL, 0, (int *)0)

       This  is the only case where indom may be equal to PM_INDOM_NULL.  If numinst is zero, or instlist is NULL, then all instances in indom are
       selected.

DIAGNOSTICS

       PM_ERR_PROFILESPEC
	      indom was PM_INDOM_NULL and instlist was not empty

CAVEAT

       It  is  possible to add non-existent instance domains and non-existent instances to an instance profile.  None of the routines that use the
       instance profile will ever issue an error if you do this.  The cost of checking, when checking is possible, outweighs any benefits.
