C SYNOPSIS

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 pro­
       file  describes  the  instances  that pmcd requires in the
       pmResult structure returned by the next  fetch.   pmdaPro­
       file simply stores the new profile.


CAVEAT

       The PMDA must be using PMDA_PROTOCOL_2 or later, as speci­
       fied in the call to pmdaDSO(3) or pmdaDaemon(3).
