DESCRIPTION

17       As  part  of  the  Performance  Metrics  Domain  Agent  (PMDA) API (see
18       PMDA(3)), pmdaStore is the generic callback for storing a value into  a
19       metric.  pmdaStore is usually a no-op as, by default, no metrics can be
20       altered.  Also, the implementation of a store callback which does  per‐
21       mit metrics to be altered by pmstore(1) is very application dependent.
22

CAVEAT

24       The  PMDA  must  be using PMDA_PROTOCOL_2 or later, as specified in the
25       call to pmdaDSO(3) or pmdaDaemon(3).
26

DIAGNOSTICS

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