DESCRIPTION

18       As  part  of  the  Performance  Metrics  Domain  Agent  (PMDA) API (see
19       PMDA(3)), pmdaPMID is the generic callback for  translating  a  dynamic
20       metric name into a PMID (pmid).
21
22       Because implementing dynamic performance metrics requires specific PMDA
23       support, and the facility is an optional  component  of  a  PMDA  (most
24       PMDAs do not support dynamic performance metrics), pmdaPMID is a skele‐
25       ton implementation that returns PM_ERR_NAME.
26
27       A PMDA that supports dynamic performance metrics will provide a private
28       callback  that replaces pmdaPMID (by assignment to version.four.pmid of
29       the pmdaInterface structure) and  implements  the  translation  from  a
30       dynamic performance metric name into the associated pmid.
31

DIAGNOSTICS

33       pmdaPMID returns PM_ERR_NAME if the name is not recognized or cannot be
34       translated, else returns 0.
35

CAVEAT

37       The PMDA must be using PMDA_PROTOCOL_4 or later, as  specified  in  the
38       call to pmdaDSO(3) or pmdaDaemon(3).
