PMDASTORE(3)						     Library Functions Manual						      PMDASTORE(3)

NAME

       pmdaStore - store a value into a metric for a PMDA

C SYNOPSIS

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

       int pmdaStore(pmResult *result, pmdaExt *pmda);

       cc ... -lpcp_pmda -lpcp

DESCRIPTION

       As part of the Performance Metrics Domain Agent (PMDA) API (see PMDA(3)), pmdaStore is the generic callback for storing a value into a met-
       ric.  pmdaStore is usually a no-op as, by default, no metrics can be altered.  Also, the implementation of a store callback which does per-
       mit metrics to be altered by pmstore(1) is very application dependent.

DIAGNOSTICS

       pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics may be modified.

CAVEAT

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

NAME

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

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/impl.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_PROTOCOL_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).
