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_INTERFACE_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.
