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_PROTOCOL_2 or later, as specified in the call to pmdaDSO(3) or
       pmdaDaemon(3).
