NAME

       pmdaProfile - update instance profile for PMDA in preparation for
       the next fetch from PMCD

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/pmda.h>

       int pmdaProfile(pmProfile *prof, pmdaExt *pmda);

       cc ... -lpcp_pmda -lpcp

DESCRIPTION

       As part of the Performance Metrics Domain Agent (PMDA) API (see
       PMDA(3)), pmdaProfile is the default callback which handles the
       receipt of a pmProfile from pmcd(1).  A profile describes the
       instances that pmcd requires in the pmResult structure returned
       by the next fetch.  pmdaProfile simply stores the new profile.

CAVEAT

       The PMDA must be using PMDA_INTERFACE_2 or later, as specified in
       the call to pmdaDSO(3) or pmdaDaemon(3).

SEE ALSO

       PMAPI(3), PMDA(3), pmdaDaemon(3), pmdaDSO(3) and pmdaFetch(3).
