pmLookupInDomArchive - translate an instance name into an
instance identifier
Синопсис C (C Synopsis)
#include <pcp/pmapi.h>
int pmLookupInDomArchive(pmInDom indom, const char *name);
cc ... -lpcp
Описание (Description)
Provided the current Performance Metrics Application Programming
Interface (PMAPI) context is associated with a set of archive
logs, pmLookupInDomArchive will scan the union of all the
instance domain metadata for the instance domain indom, locate
the first instance with the external identification given by
name, and return the internal instance identifier.
This routine is a specialized version of the more general PMAPI
routine pmLookupInDom.
Only the leading non-space characters of name will be used to
identify the instance.
The value for the instance domain indom is typically extracted
from a pmDesc structure, following a call to pmLookupDesc(3) for
a particular performance metric.
pmLookupInDomArchive will return a positive instance identifier
on success.
