pmdaStore - store a value into a metric for a PMDA
#include <pcp/pmapi.h> #include <pcp/pmda.h> int pmdaStore(pmResult *result, pmdaExt *pmda); cc ... -lpcp_pmda -lpcp
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.
pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics may be modified.
The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in the call to pmdaDSO(3) or pmdaDaemon(3).
