NAME         top

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

C SYNOPSIS         top

       #include <pcp/pmapi.h>

DESCRIPTION         top

       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         top

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