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
24 pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics may be
25 modified.
26
28 The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in the
29 call to pmdaDSO(3) or pmdaDaemon(3).
