Описание (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.
Предостережение (Caveat)
The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in
the call to pmdaDSO(3) or pmdaDaemon(3).
Диагностика (Diagnostic)
pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics
may be modified.
