Описание (Description)

As part of the Performance Metrics Domain Agent (PMDA) API (see
       PMDA(3)), pmdaPMID is the generic callback for translating a
       dynamic metric name into a PMID (pmid).

       Because implementing dynamic performance metrics requires
       specific PMDA support, and the facility is an optional component
       of a PMDA (most PMDAs do not support dynamic performance
       metrics), pmdaPMID is a skeleton implementation that returns
       PM_ERR_NAME.

       A PMDA that supports dynamic performance metrics will provide a
       private callback that replaces pmdaPMID (by assignment to
       version.four.pmid of the pmdaInterface structure) and implements
       the translation from a dynamic performance metric name into the
       associated pmid.

Предостережение (Caveat)

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

---

Диагностика (Diagnostic)

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