Описание (Description)
As part of the Performance Metrics Domain Agent (PMDA) API (see
PMDA(3)), pmdaName is the generic callback for translating a pmid
into one or more dynamic metric names (nameset).
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), pmdaName is a skeleton implementation that returns
PM_ERR_NAME.
A PMDA that supports dynamic performance metrics will provide a
private callback that replaces pmdaName (by assignment to
version.four.name of the pmdaInterface structure) and implements
the translation from a pmid to a set of dynamic performance
metric names returned via nameset. The behaviour, return values
and memory allocation rules for nameset are the same as for
pmNameAll(3).
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)
pmdaName returns PM_ERR_PMID if the name is not recognized or
cannot be translated, otherwise the number of metric names found
(most commonly 1).
