NAME

       pmdaStore - store a value into a metric for a PMDA

C SYNOPSIS

       #include <pcp/pmapi.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 metric.  pmdaStore is usually a no-op  as,  by
       default,  no  metrics  can be altered.  Also, the implementation of a store callback which
       does permit metrics to be altered by pmstore(1) is very application dependent.

CAVEAT

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

DIAGNOSTICS

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