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 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).
