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.
